
I can identify and correctly use common lab
equipment used in the chemistry laboratory.

A small glass container used to view
chemical reactions or to heat small
amounts of a substance

Like a dropper, it is used to
transfer and dispense small
amounts of a liquid.



This connects to the gas source
in the lab.
The gas source provides the fuel
for a flame.
The flame is used to heat
substances.

Liquid
volume is
measured
in mL
A wide-mouthed container
used to transport, heat, and
store substances.
Can be used to measure liquid
volume only if measurements
do not need to be precise.
Always read from eye level.
Notice that there are two scales
on the beaker! Use the one that
zero is at the bottom (right) if you
are measuring the liquid.
•Take a beaker from the drying rack
on the center lab table and place 50mL
of water into the beaker.
•Get it approved by your teacher.
•Empty the water and return the
beaker to the drying rack.
•Return to your seat.

Used to measure volume very
precisely.
First, determine what each line
means.
Always read from eye level.
Always read the bottom of the
meniscus (the dip).
•Look at each graduated cylinder and
write down the quantity each line
represents.
#1) 1mL
#3) 1mL
#2) 0.5mL
#4) 0.2 mL

Place water in the graduated cylinder.
Record the water level.
Sink the object into the water.
Record the new water level.
Subtract the two water levels.
The answer is the volume.
Change the mL to cm3.

Water Before: 30mL
Water After: 40mL
40-30 =10
Difference is 10mL
Object’s Volume: 10cm3


Measure the length.
Measure the width.
Measure the height.
Multiply these together: L x W x H


Measures the mass of
objects and substances.
NEVER PUT YOUR HAND ON
THE BALANCE PAN!!!




Remove anything that is on the balance pan.
Turn the balance on to “zero out” (this is also
called “tare”). This means that the reading
should be 0.00 when there is nothing on the
pan. If it is not zero, hit the tare button.
Place the object on the pan.
Record the reading in grams (g).

Remove anything that is on the balance pan.
Place a sheet of paper on the pan.
Turn the balance on to “zero out” or press the
tare button. This means that the reading
should be 0.00 when there is paper on the
pan.
Place the powder on the paper.
Record the reading in grams (g).

Place the empty beaker, flask, or graduated
cylinder on the pan.
Record the reading in grams (g).
Remove the glassware and add the liquid.
Measure the mass of the glassware and the
liquid.
Subtract the mass of the empty glassware from
the mass of the glassware with the liquid to
determine the mass of the liquid.


The mass of an empty beaker is 116g.
The mass of a beaker with 100mL of water in
it is 217g.
You would subtract 116 from 217:
◦ 217g-116g=101g.
◦ The mass of 100mL of water is 101g.
