Lab Equipment

Beaker Used to hold and heat liquids

Test Tube Brush Used to clean test tubes

Beaker Tongs Used to handle hot beakers

Bunsen Burner Used for heating and exposing items to flame.

Crucible used to hold small amounts of chemicals during heating at high temperatures

graduated cylinder accurately measures liquid volumes

Stirring Rod used for stirring

evaporating dish liquids are heated over a flame so that they evaporate, leaving a solid residue

crucible tongs to hold hot crucibles

forceps used to pick up or hold small items

watch glass to hold solids while being weighed, or as a cover for a beaker

thermometer measures temperature (science uses degrees in Celsius)

Test Tube open tube used to hold liquids

test tube clamp clamp used to hold hot test-tube

dropper pipet or disposable pipet for drawing in a liquid and expelling it in drops

funnel for pouring liquid or other substance through a small opening

mortar and pestle used to crush solids into powders for experiments

rubber stopper used to cover ends of test tubes and flasks

spatula small scoop used to transfer powder and crystal chemicals

wire gauze used to support a container (such as a beaker or flask) during heating

ring stand Ring stands are used to hold items being heated.

Erlenmeyer flask used to hold liquids, has narrow neck to prevent splashes

ring clamp used with ring stand to hold a glass container

clay triangle used to hold a crucible while the crucible is heated

goggles protects eyes from chemical splashes
