Litmus paper red:
changes colour from red to blue when conditions change from
acidic to alkaline.
Recommended application:
General test for acidic or alkaline reaction: It serves in neutralisation reactions to check whether the change from acid to alkaline or vice versa has taken place. Litmus paper is the bestknown indicator paper.
Chemistry: Litmus is not a single, chemically defined substance but a natural product containing a mixture of substances. It is extracted from lichen and probably represents the
oldest known indicator dye.

Test papers
These products are produced by total impregnation of the paper with a pH indicator or a mixture of several indicator dyes.
MACHEREY-NAGEL universal indicator paper covers the pH
renges 1 – 11 and 1 – 14; gradation of the colour scale is in
steps of 1.0 pH units or 1.0/2.0 units, respectively.
MACHEREY-NAGEL special indicator papers (narrow range
papers) usually cover a range of about 2 – 5 pH units in gradations of 0.2/0.3 or 0.5 units. Please note that indicator papers measure the pH of unbuffered or only weakly buffered
solutions less accurately than do indicator solutions. When
dealing with buffered solutions, however, indicator papers
work with the same degree of accuracy.
For pH measurements in weakly buffered or unbuffered solutions we recommend pH-Fix indicator sticks. The following
procedure is recommended when you attempt to measure the
pH value of unbuffered or weakly buffered solutions with universal or special indicator papers: a strip of indicator paper is
placed against the wall of a test tube which is then filled to the
brim with the solution to be tested. The indicator paper is left
in the test tube and its colour, viewed through the glass, is
compared with the colour scale after about 1 minute.

DUOTEST double-zone indicator papers
TRITEST triple-zone indicator papers
Test papers
TRITEST paper is an indicator paper combining highes accuracy with greatest ease of reading. Three complementary indicator zones on a single strip guarantee clear colour
differentiation and the possibility to estimate in-between values. The gradation is 1.0 pH unit. TRITEST is available for the
range pH 1–11, but in two types:
DUOTEST papers are indicator papers with greater accuracy
and increased ease of reading. Two complementary indicator
zones on one strip – separated by a white centre band – guarantee clear colour differentiation and a more accurate estimate of intermediate values. The white centre band is
hydrophobic and prevents that colours of the two indicator
zones run into one another, thus increasing accuracy. In addition the white band forms a good contrast to the coloured
test zones and furthermore adds mechanical strength to the
wet strip, because it repels water.
a) TRITEST in reel form (without hydrophobic zone)
paper strip of 10 mm width to which three adjoining indicator zones (1 main indicator and 2 auxiliary indicators)
have been applied
b) TRITEST L in reel form (with 2 hydrophobic zones)
paper strip of 6 m length and 14 mm width to which three
indicator zones (1 main indicator and 2 auxiliary indicators) have been applied. The indicator zones are separated by hydrophobic barriers. This guarantees a sharp
separation of the indicator zones which is of particular
advantage in pH determinations in the highly alkaline
range.

pH indicator papers
PEHANON® indicator papers
for pH measurement in coloured solutions
The indicator zone (unprinted field of about 6 mm width) is in
the middle of the strip, the comparison fields (4 mm wide) are
arranged above and below. The strip is submerged in the solution for about three seconds so that all colour zones are
wetted. The indicator zone (unprinted centre field) changes
colour according to the pH value of the solution and is then
compared against the colour fields on the strip. The pH value
is read from the closest matching field. An invisible hydropho-
Test papers
PEHANON® is a series of pH indicator papers where the indicator and colour scale are combined on a single strip. They
permit a fast, convenient and accurate determination of the
pH value since they eliminate the necessity to compare the
colour field against a separate scale. pH values are imprinted
on the strips. This presentation also permits the pH measurement of coloured solutions and suspensions, since the colour
of the test solution acts on the colour scale in the same manner as on the indicator field, resulting in a comparison of
mixed colours. The individual colour zones are separated by
hydrophobic barriers.
bic silicone barrier just above the top colour field prevents
capillary action of the test solution beyond that point and allows safe and clean handling with corrosive, toxic or otherwise noxious liquids.
The PEHANON® series covers the entire pH range from
0 to 14 with one universal paper and thirteen narrow ranges
which overlap to permit utmost selectivity for the range suited
to each particular need. The pH gradations within each strip
have been established to offer maximum colour differentiation from one comparison field to the next depending on the
individual indicator.
PEHANON® papers guarantee highest accuracy even when
testing coloured solutions! Again – as with universal and special indicator papers – best results are obtained for buffered
solutions and suspensions (see page 7).

pH indicator papers
pH-Fix indicator sticks – non-bleeding –
Recommended for pH measurement in weakly buffered or strongly alkaline solutions
Test papers
pH-Fix indicator sticks are for the rapid measurement of the
pH of a water sample.
In contrast to standard test papers, the pH-Fix indicator is
chemically bound to the cellulose fibres, avoiding bleeding
even in strongly alkaline samples. Furthermore there are the
following advantages:
Measurement of pH values is possible even in unbuffered solutions, since the sticks can be left in the solution
until the final reaction colour is obtanined.
Test samples are not contaminated by the indicator
dyes. Thus solutions can be used for further investigations.
Colours of the individual colour fields cannot run into
each other. This allows a more precise comparison the
the colour scale.
Specially developed indicator dyes guarantee a sharp
differentiation between the individual pH values and a
clear and easy comparison with the colour scale.
Length and stability of the plastic strips protect fingers
from contact with the test solution.

Liquid indicators
UNISOL indicator solutions for pH measurement in liquids
For pH measurement in pure water, in surface waters, in
very diluted acids or bases – i. e. in weakly buffered solutions – indicator papers find their limit of applicability
(acid-base error). For these applicaitons indicator solutions
are used, which are added to the analyte fluid. The resulting
colour is directly compared with the colour scale (UNISOL,
VISOCOLOR® ).
UNISOL indicator solutions are available for measurements
in different pH ranges.
UNISOL 113 covers the pH range from 1 to 13 and shows
several colour changes within this range. Starting on the acid
side the colour changes from red via yellow and green to
blue-violet, when the pH of the solution is increased successively. The gradation of the printed colour scale is in 1.0 pH
units.
UNISOL 410 covers the more narrow range pH 4 – 10 with a
gradation of 0.5 units on the colour scale.
Fields of application:
pure water and waste water
water for aquariums
unbuffered solutions
surfaces of paper and similar products
UNISOL indicator solutions offer simple and convenient handling.
With UNISOL 113 one drop of the indicator solution, with
UNISOL 410 two drops are added to 5 ml of the colourless
Test papers
aqueous solution to be tested. The resulting colour is compared with the corresponding colour scale. One has to pay
attention, however, to the fact that the colour intensity depends on the indicator concentration and the thickness of the
coloured layer of the test solution. Spot plates or ordinary test
tubes may be used, but we recommend to use square measuring cells since the thickness of the layer is always constant
and permits accurate readings. Measuring cuvettes made
from glass or quartz are very expensive and, due to the danger of breakage, too valuable for rapid pH measurements outside the laboratory.
Precise pH results can be obtained by using the included
plastic cuvette MN 13/72, because it was used to balance colours for printing the colour scales.

colorimetric determination
photometric determination
Colorimetric pH measurement is based on colour comparison
in a comparator. The transparent coloured solution allows an
unambiguous assignment of the pH value even for inexperienced eyes. These products are especially recommended for
the pH measurement in unbuffered solutions, e. g. of surface
waters (see page 50).
The efficient NANOCOLOR® photometers, too, allow pH
measurements independent of the human eye (see page 73,
86).

Plumbtesmo®
Cat. No. 907 27
Cat. No. 907 53
Potassium iodate starch paper is a filter paper impregnated
with potassium iodate (KIO3) and starch, which is used for the
detection of sulphurous acid (H2SO3) and alkali sulphites.
The stoichiometry of the reaction is as follows:
2 IO3– + 5 SO32– + 2 H+ → 5 SO42– + I2 + H2O
The sulphurous acid reduces potassium iodate to form elemental iodine which reacts with the starch to a blue-violet
complex. Thus the white potassium iodate starch paper turns
blue-violet in the presence of H2SO3.
Limit of sensitivity: 5 mg/l SO2
Recommended application: detection of sulphur dioxide
(SO2) in the chemical laboratory, testing of meat products
suspected of containing added sulphite.

Udder test paper
Cat. No. 907 48
The udder test paper is a specially adapted indicator paper for
the rapid determination of streptococcal mastitis. Milk of cows
infected with this disease cannot be sold, if it is obviously
changed. Most cases of mastitis cause the pH value of the
milk to depart from the normal value, and the udder test paper
detects such changes. Occasionally, only one teat of an udder shows symptoms of the infection. Consequently, all four
teats require testing. The udder test paper contains four indicator areas, one for a sample from each teat.
Colour reaction: The milk of healthy cows changes the indicator colour to yellowish-green (pH 6.4 – 6.6). Milk from moderately afflicted animals causes the colour to turn green (pH
about 7) while milk from severe cases of mastitis gives rise to
different shades of blue (pH 7 – 8 or higher). If the indicator
remains yellow, the milk shows a pronounced acidic pH value
(pH 6.3 or less) indicating other types of diseases.
Presentation: 20 udder test papers 90 x 140 mm in PE bags,
with four indicator spots and imprinted cow and udder symbol.
Additionally the papers provide space for individual remarks.

Wator

Indicator paper for the determination of water in butter
according to DIN 10 311
The storage life of butter is closely linked to the size of the water and buttermilk particles it contains. For this reason it is important to check the water distribution during the manufacturing process and before storing larger quantities. The WATOR
indicator paper allows an exact means for controlling the water distribution. Evaluation charts according to the 5-point
evaluation system are available on request.
On contact with water WATOR develops dark-blue spots, the
size and number of which is correlated to the distribution of
the water in the butter.
Watesmo
Cat. No. 906 09
WATESMO is a test paper for the detection of water in the liquid as well as the vapour phase
a) in the liquid phase
in aliphatic and aromatic hydrocarbons (gasoline, oil), in
isopropanol and higher alcohols, in waxes, for determination of absorptive moisture in salts,
in solid fats as well as aqueous emulsions of ointment
bases
Depending on the type of sample, a water content of more
than 10 – 15% can be indicated with WATESMO paper.
b) in the vapour phase (indirect determination)
the test strip is dipped into absolutely anhydrous Isopropanol and, while still moist, is placed into the medium to
be tested, such as a current of air. The isopropanol acts
as a solvent aid between the water vapour and
WATESMO. After evaporation of the alcohol in the driest possible atmosphere, a blue colour will appear, the
intensity of which depends on the amount of water vapour present.
WATESMO changes colour from light blue to deep blue. Do
not touch the test paper, except with absolutely dry fingers or
forceps. When dry, the paper does not react with atmospheric
moisture.
WATESMO indicates the absence of water, if the test strip remains colourless after evaporation of the solvent. Therefore it
can be used to indicate water seeping into waterproof containers, through impermeable clothing or other watertight
products.
Exceptions and sources of error:
WATESMO cannot be used where methanol, dimethylformamide, dimethylsulphoxide or mixtures containing these
solvents are present. When dipped onto a solvent containing
substantial amounts of water, the test strips turns deep blue
immediately, i. e. even prior to evaporation of the solvent.
Allowing the test paper to dry in a moist atmosphere may also
produce a blue colour. Drying in a desiccator may therefore
be indicated (see above under b).

QUANTOFIX® Cyanide
Test papers
Test sticks for the semi-quantitative determination of chloride
(Cl–) in solutions
Range: 500 – 3000 mg/l Cl–
QUANTOFIX® Chloride uses the same general principle as
the AQUADUR® test sticks (see page 28).
In the pH range 2 to 12 the reaction is independent of the pH
value of the solution to be analysed. Strongly acidic solutions
have to be adjusted to pH 5 – 7 with sodium hydroxide solution, alkaline solutions are adjusted to the same pH range
with nitric acid. Chloride concentrations greater 3000 mg/l
can be determined after defined dilution of the test sample
with distilled water.
The following ions only interfere above the indicated concentrations:

Test sticks for the semi-quantitative determination of ethylenediaminetetraacetic acid (EDTA) in solutions
Range: 100 – 400 mg/l EDTA
Complexing agents such as ethylenediaminetetraacetic acid
(EDTA) are frequently used as additives in washing and
cleansing agents, cosmetics, in the photographic industry or
paper industry. Since the biological degradation of such compounds is very difficult, their dosing should be thorougly monitored. The proper dosage concentration can be checked with
QUANTOFIX® EDTA. The test sticks can also be used to detect the absence of complexing agents.
The following complexing agents can also be determined with
this method: nitrilotriacetic acid (NTA), cyclohexanedinitrilo(1,2)-tetraacetic acid, diethyltrinitrilopentaacetic acid, bis(aminoethyl)glycol ether N,N,N’,N’-tetraacetic acid.

QUANTOFIX® Nitrate/Nitrite
Cat. No. 913 13
Test sticks for the semi-quantitative determination of nitrate
and nitrite in solutions
Range: 10 – 500 mg/l NO3–, 1 – 80 mg/l NO2–
Because nitrite interferes with the determination of nitrate, the
test sticks contain an additional test field for nitrite. If this upper test field turns red indicating the presence of nitrite, the
NO2– has to be destroyed with amidosulphuric acid (Cat. No.
918 973); then the nitrate test is repeated with another test
stick. Following this procedure, 10 mg/l nitrate can be determined even when 1000 mg/l nitrite are present. Store nitrate

the AQUADUR® test sticks (see page 28).
Between pH 4 and 8 the reaction is independent of the pH value of the test solution. Strongly acidic samples have to be adjusted with sodium acetate, alkaline solutions are adjusted
using tartaric acid.
The following ions only interfere above the indicated concentrations:
> 1000 mg/l BrO3–, ClO3–, CrO42–, SO32–, S2O52–, SeO32–,
> 500 mg/l S2O42–, > 100 mg/l CN–, S2–
QUANTOFIX® Sulphite
Cat. No. 913 06
Test sticks for the semi-quantitative determination of sulphite
in solutions
Range: 10 – 1000 mg/l SO32–
Strongly or weakly acidic solutions have to be buffered with
solid sodium acetate prior to testing, since the test paper does
not react with sulphites in acidic media. Sulphide ions interfere since they also produce a red reaction colour of the test
paper in neutral solution. This interference can be eliminated
by the addition of an excess of nickel(II) ions. The NiS formed
can be removed by filtration. Larger amounts of reducing
agents, such as hydroxylammonium chloride or ascorbic acid, interfere, causing low sulphite results.

QUANTOFIX® Multisticks for aquarium owners
Cat. No. 913 26 / 913 27
Test sticks for the semi-quantitative determination of the total
hardness (Ca2+, Mg2+), carbonate hardness (HCO3–, CO32–)
and the pH value of aquarium water
Ranges:
total hardness
5° – 25 °d
carbonate hardness 3° – 20 °d
pH value
6,4 – 8,4
The total hardness of a water is caused by its content of calcium and magnesium salts (Ca2+, Mg2+). When measuring
the total hardness, the sum of these salts is determined.
The carbonate hardness is a part of the total hardness and
is caused by that portion of alkaline earth metals which are
equivalent to the carbonate and hydrogen carbonate ions
(CO32–, HCO3–) present in the water. The carbonate hardness is thus a measure for the buffer properties of the water.
Water with a low carbonate hardness is not sufficiently buffered, therefore the pH value can fluctuate easily.
The pH value indicates whether the water is acidic, alkaline
or neutral. Water with a pH of 7 is called neutral. Towards lower pH values the water becomes increasingly acidic, towards
higher pH values it becomes more alkaline.
The QUANTOFIX® multisticks are a convenient tool for orienting measurement of these three parameters, which are
very important for aquarium waters.

During operation of a fixing bath it is necessary to check the
silver content as well as the pH in regular intervals to insure
proper operation. A decrease in fixing capacity is noted as an
increase in silver concentration or an alteration of the pH value. The convenient Ag-Fix test sticks from MACHEREYNAGEL allow a simultaneous semi-quantitative determination
of silver and the pH value in photographic solutions.
With these sticks two paper zones are sealed onto the lower
end of a plastic strip, one for the determination of the silver
concentration and one for pH measurement. After dipping the
test sticks in the test solution the colours of the test zones are
compared with the colour scale on the container. Ag-Fix
comes in packages of 100 test sticks. The length of the sticks
has been chosen for safe and convenient handling.
The plug of the container is filled with a desiccant resulting in
a shelf life of 2 1/2 years for Ag-Fix sticks.
The determination is very simple: remove only as many sticks
as are required and close the container immediately. Do not
touch the test paper zone. Dip the test stick briefly into the fixing bath and strip of excess liquid. After 30 seconds compare
the test fields with the colour scale and read off results. AgFix test sticks and Ag-Fix paper are not suited for fixing baths
with pH values below 4. Concentrations above 10 g per litre
can be determined after dilution of the fixing bath.
Iron and copper ions interfere and show a falsely positive reaction. These ions can be determined with the test sticks
QUANTOFIX® Iron 100 (Cat. No. 913 08), QUANTOFIX® Iron

Test papers
Test sticks for determination of the water hardness
The hardness of water depends on its content of calcium and
magnesium salts. When measuring the total hardness, the
sum of these salts is determined.
It is expressed in mmol/l or in degrees of hardness, whereby
it is important to differentiate between German, English and
French values:
in Germany:
1 °d = 10 mg/l CaO = 17,8 mg/l CaCO3
in England:
1 °e = 14.3 mg/l CaCO3
in France
1 °f = 10 mg/l CaCO3
Conversion factors: 1 °d = 1.25 °e = 1.78 °f = 0.178 mmol/l
In the USA, the water hardness is simply expressed in terms
of mg/l CaCO3.
Apart from the above values, water is often simply classified
as "soft water", or "hard water" etc. The following values generally apply to these terms:
below 50 mg/l CaCO3 – very soft water
50 – 120 mg/l CaCO3 – soft water
120 – 240 mg/l CaCO3 – medium hard water
240 – 360 mg/l CaCO3 – hard water
above 360 mg/l CaCO3 – very hard water
The hardness of water is often of importance where no laboratory facilities for the analytical determination exist. In these
cases Aquadur® provides a quick method for an indicative
reading. Its sensitivity is adequate for textile establishments
of moderate size, in dyeing, laundries, small water works,
boiler rooms as well as in pisciculture, aquaria and also for
household use.
Sensitivity: Aquadur® allows the determination of the water
hardness from 0 to over 21 °d, i.e. up to about 360 mg/l
CaCO3. Standard gradations are:
0 – 5 – 10 – 15 – 20 – 25 °d or 0 – 4 – 7 – 14 – 21 °d
Other sizes and other gradations are available (bulk package
with 5000 sticks or single-sealed [pack of 1000]).

Gradation 0 – 2 – 5 – 10 – 20 – 50 – 100 mg/l F–
(each kit contains a colour comparison scale)
The reaction is based on the bleaching action of fluoride ions
on an aluminium colour complex.
The fluoride test is especially suited for rapid control of fluoride concentrations. Its purpose is to define concentration
ranges and to detect values which fall short of or exceed given limits. Chlorates and bromates cause white discolourations of the test paper. Addition of sodium dithionite
(Na2S2O4) will circumvent this interference without affecting
the fluoride test.
Large concentrations of sulphate also cause discolorations.
Addition of barium chloride (BaCl2) eliminates this interference. When testing intensely coloured solutions the colour of
the sample must be taken into account for evaluation.
INDIQUAT
Colour reaction: green → red
Method of application: Dip the stick briefly into the water and

Ozone is a colourless toxic gas. It is irritating to eyes and mucous membranes and can cause respiratory complaints. An
ozone content of 180 µg/m3 is considered as critical value
above which sensitive persons should avoid stronger physical exertion. The ozone values published by public media like
press, radio or TV represent the ozone concentrations in the
vicinity of the measuring stations. However, actual ozone values in other locations can considerably deviate from these
published values due to meteorological and chemical influences such as wind, solar radiation, exhaust gases from vehicles etc. For this reason a local measurement of ozone
concentrations is recommended.
Ozone test sticks are a convenient test for orienting determination of the ozone concentration in air. Similar to the
QUANTOFIX® test sticks they consists of plastic strips
10 mm wide, onto which a test paper has been sealed at the
lower end. This allows easy handling of the test.

Interferences: Other oxidising reagents (e. g. chlorine) cause
a similar colour change and simulate higher ozone values.
The measuring ranges are valid for a relative atmospheric humidity of 30 to 60 %. Humidity values below 30 % can cause
low ozone results, humidity above 60 % can result in higher
ozone values.
Saltesmo
Cat. No. 906 08
Test paper for the quantitative determination of halide ions
This test is based on a reaction between the halide ions Cl–,
Br–, I– and a coloured silver salt, which is decolourised by the
reaction. Although the paper will react with all of the above halides, it is most frequently used for the determination of chloride
and thus, indirectly, for the detection of NaCl. It is for this purpose that Saltesmo paper is specially recommended.
Saltesmo is most commonly used in the analysis of foodstuffs1). It is an accepted practice to calculate the total halide
content of a given sample, converted to the equivalent NaCl
value, as the chloride content of the sample. The determination of the chloride content is important for the quality control
and also permits comparison between different brands of the
same product, e. g. tomato products1).
The Saltesmo reaction is a "micro-titration on paper"2). As
such, it is particularly suited for rapid checks on halogen ion
or halide concentrations. Its purpose is to define concentration ranges and to detect values which fall short of or exceed
labelled amounts.
Cyanide and thiocyanate also bleach the brown colour. Fluoride ions do not interfere.
Limit of sensitivity: Saltesmo permits the semi-quantitative
determination of NaCl.
Concentration gradations:
0 – 0,25 – 0,5 – 1 – 2 – 3 – 4 – 5 g NaCl/litre
