For exact volume measurements of liquids. Pipet on the left is a Volumetric pipet. It has only one graduation for delivering one exact volume. Pipet on the right is a Mohr pipet. It has graduations for delivering any number of exact volumes.	Pipet	There are several styles of fillers available to draw liquids into a pipet. Use of the standard pipet bulb is described on the lab techniques page. Never draw a liquid into a pipet with your mouth.	Pipet filler
Used in conjunction with a vacuum connection to a water faucet to speed up filtration.	Filter flask	The Erlenmeyer flask is the most common flask in the chemistry lab. It is used to contain reaction solutions.	Erlenmeyer 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.	Florence flask	The volumetric flask is used to make solutions. It has a precise graduation line in the neck of the flask. A solute is placed into the flask, then the solvent is used to bring the total volume up to the graduation.	Volumetric flask
Beakers 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.	Beaker	Used for accurate measurements of liquid volumes. The bumper ring on cylinders is NOT for measuring. It is to prevent breakage if tipped over. Keep it near the top.	Graduated cylinder
This dish is used to recover dissolved solids by evaporation. It is made for heating, but should not be used for "strong" heating.	Evaporating dish	A watch glass can be used like an evaporating dish for very small amounts of liquid. It can also be used to cover beakers.	Watch glass
When attached to the ring stand, this iron ring is used to support glassware above the lab table.	Support ring	When attached to the ring stand, this clamp is used to hold a large test tube or Florance flask above the lab table.	Utility clamp
Crucibles are used as a container when something requires "strong" heating.	Crucible and cover	These tongs are used for picking up crucibles and crucible covers only.	Crucible tongs
Used as a support for beakers and other glassware when placed across a support ring.	Wire gauze	Used to light a lab burner. Not a toy noisemaker during lab.	Striker
Used to grind solids into powers.	Mortar and Pestle	Used to hold test tubes for short periods of "gentle" heating.	Test tube holder
When lined with filter paper, used to filter suspended solids from a liquid. DO NOT use a filter funnel to transfer liquids from one container to another.	Filter funnel	Used for rinsing solids out of a container when filtering - or whenever a small amount of distilled water is needed.	Wash bottle
Used to transfer solids from their original storage container.	Chemical spoon	Used to close hoses by pinching them together.	Hose clamps
Dessicators are used to provide a dry environment for a crucible or substance to cool down. This is critical in quantitative work where moisture can affect mass results. A common dessicant is anhydrous calcium chloride. Colored indicator crystals are often included to tell the user the condition of the dessicant. A gray color in the crystals usually indicates that the dessicant is dry and will absorb moisture. A pink color usually means that the dessicant is "hydrated". When this happens, the water can be removed by heating the dessicant in an oven.			Desiccator
