Lab Equipment and
Procedures!!!!
Erlenmeyer Flask
• The Erlenmeyer flask is the most
common flask in the chemistry lab. It is
used to contain reactions.
Florence Flask
The rounded bottom of the Florence flask
makes it ideal for boiling liquids. It also makes this flask easy to tip
over when sitting on the lab table.
BeakersBeakers are the
most versatile glassware in the lab and can be used for just about anything.
The volume graduations on
beakers should be used only for
"ballpark" estimates.
Graduated cylinder
Used to make accurate measurements of
liquid volumes. The bumper ring on larger cylinders is to prevent
breakage if tipped over. Keep it near the
top.
Evaporating Dish
This evaporating dish is used to
recover dissolved solids by evaporation.
While it can be heated, it should not be used for "strong"
heating.
Watch Glass
A watch glass can be used like an
evaporating dish for very small amounts of liquid. It can also be
used to cover beakers or evaporating dishes.
Ring Stand and Iron Ring
When attached to the ring stand, this iron ring is used to support glassware
above the lab table.
Crucibles
Crucibles are used as a
container when something
requires "strong" heating.
Tongs
These tongs are used for picking up
crucibles and crucible covers
only.
Mortar and Pestle
Used to grind solids into powers.
Test Tube Holder and Rack
The test tube holder is used when
heating a substance in the test tube
over an open flame.
The test tube rack is used for storing test tubes so that they do
not tip over.
Buret
A buret is used to measure volumes of
solutions during a titration.
Plastic Wash Bottle
A plastic wash bottle is used
to dispense water.
Funnel
A funnel is used for filtrations
where solids are separated from
liquids.
Goggles
Goggles are used to protect you eyes during
lab.
Scoopula and Forcep
A forcep is used to hold or pick upsmall objects.
A scoopula (or spatula) is used to
transfer solid chemicals.
Clay Triangle
A clay triangle is used to support
a crucible.
Double Buret Clamp
The double buret clamp is used for
holding burets during a titration. They can also be used to hold
a eudiometer.
Bunsen Burner
The Bunsen burner is a gas burner
used forheating
substances.
Wire Gauze
Wire gauze is used to spread
the heat of a Bunsen
burner.
Stirring Rod
Big shock…these are used for
stirring…. But please do not use
them to crush things…
They are glass and they will break.
How to…
• Light a Bunsen Burner
• Read a graduated cylinder
• Use a digital balance
