SET A
SET B
SET C
Used to decrease exposure to light.
example, Bilirubin standards
Least expensive but poor resistance Has excellent optical properties.
to high temperature. Only fair
Used for high precision analytic
resistance to chemicals
work, optical reflectors, mirrors
SET D
SET E
SET F
used for high alkali solutions. Alkali
resistant. Poor heat resistant
Can able to resist clouding due to
alkali and scratching.
High resistance to thermal shock
and chemical attack. Heavy walls to
minimize breakage. They are used
for most beakers, flasks and
pipettes.
2. IDENTIFY THE TYPE OF PLASTICWARE
SET A
SET B
SET C
Relatively inert chemically,
Resistant to most acids, alkali’s and
salt. Can be autoclaved. Used for
pipette, test tubes
Relatively inert chemically,
Resistant to most acids except
(Conc. H2s04) alkali and salts. Used
for test tubes , bottles, disposable
transfer pipettes, test tube racks.
Cant be autoclaved
Stronger that polyethylene and
better temperature tolerance, but
not chemical resistant.
SET D
SET E
SET F
Rigid, clear, shouldn’t be
autoclaved. Will crack and slinter.
Used for test tubes graduated
tubes
Soft and flexible but porous.
Frequently used as tubing
Extremely inert. Excellent
temperature tolerance and
chemical resistance. Used for stir
bars, stopcocks and tubing.

Pear shaped, long neck with single
calibration mark.
Used to prepare standards and
reagents. Should not be used to
store solution.
Upright, straight sided tube with
flared base. Used for non critical
measurements most TD.
5. Identify the type of pipette
SET A
SET B
SET C
Transer pipette. Single calibration
mark. Calibrated to accurately
deliver fixed volume of non viscous
sample and standard. Touch off last
drop against wall of receiving
vessel
Transfer Pipette. Similar to
volumetric pipette, bulb closer to
the tip. Etched ring means blowout.
Used for accurate measurement of
viscous fluids example, whole
blood . Not widely used
Graduated measuring pipette.
Graduation marks down to tip.
Etched ring means blowout. An
used for serial dilutions and
measuring reagents. Not accurate
enough for measuring samples and
standards
SET D
