Laboratory Equipment and Skills

Recognizing Lab Equipment

Ring Stand

support for rings, clamps, or other lab equipment

iron ring

support device for beakers, flasks, or other lab equipment

beaker

container, may be used like a cup, can be heated

graduated cylinder

makes precision volume measurements

funnel

pouring liquids into buret or flask holding filter paper

test tube clamp

holds test tubes or other equipment

test tube

container, glass versions can be heated

test tube rack

holds test tubes in upright position

test tube holder

allows for test tubes to be transferred or moved without touching with hands

volumetric flask

preparation of solutions, precision volume measurements

erlenmeyer flask

container, less evaporation than beaker, can be heated

florence flask

container, can be heated

buret clamp

holds burets when conducting volumetric experiments

well plate

holds liquids in micro experiments

wire gauze

spread heat of flame, cooling heated container

clay triangle

supports items being heated on ring stand

evaporating dish

holds small amounts of liquids, can be heated

tongs

pick up and hold beakers

triple beam balance

most accurate method to determine mass, requires experience to use

pneumatic trough

holds water, gas collection bottles, and gas collection tubes

buret funnel

designed to pour liquids into burets

triangle file

used to etch glass, used for filing

stoppers

seals flasks and bottles

crucible and lid

allows small sampes to be heated to extreme temperatures

test tube brush

used for cleaning lab equipment

glass stirring rod

to stir liquids without transfer of heat

spatula

transfer solid chemicals for weighing

gas collection tube

used to collect and measure volumes of gas from experiments

thermometer

measures temperature of gas or liquid samples

wash bottle

dispenses distilled water

forceps

pick up or hold small objects

watch glass

can cover beakers used in evaporating small amounts of liquids

pinch clamp

clamps together rubber hoses

dropper

transfer small amounts of liquid

bunsen burner

produces medium heat flame, the standard lab burner

tirrill burner

produces very high heat flame, much hotter than a bunsen burner

meker burner

produces a very large high heat flame, bigger flame tjan tirril burner, hotter flame than bunsen burner

mortar and pestle

used to grind solid chemicals to a powder

buret

used for precision volume measurements
