Beaker

Used to hold and pour liquids

Buret

Used to add small but precisely measured volumes of liquid to a solution; use for titration experiments

Platform Balance (triple beam)

Precise scale operated by moving a set of three weights (100, 10, and 1 g incriments); to find weight, sum readings of rear, middle, and front weights

Crucible Tongs

Used to handel objects that are too hot to touch

Dropper Pipette

Used to add small amounts of liquid to a solution when precision is not needed.

Erlenmeyer Flask

A flask used for heating liquids with a conic shape that allows stirring.

Evaporating Dish

Used to hold liquids for evaporation; wide mouth allows vapor to escape.

Florence Flask

Used to boil liquids with a small neck to prevent excessive evaporation/splashing.

Pipette Bulb

Used to draw liquid into a pipette; made of rubber

Graduated Cylinder

Used for measuring precise amounts of liquid to be poured at once.

Graduated Pipette

Used to transfer small and precise volumes of liquid from one container to annother.

Rubber Policeman

Hard-tipped rubber scraper used to transfer precipitate

Volumetric Pipette

Used to transfer small ammounts of liquid; only good for one particular volume. Extremely inaccurate for all other volumes.

Volumetic Flask

Used to precisely measure one volume; extremely inaccurate for all other volumes.
