Common Science Lab Equipment Biology I, Biology II, Physics

Erlenmeyer Flask Measures volume Can store liquids for a small amount of time Used for reactions Not accurate or precise

Florence Flask Volume holder Good for boiling liquids Easy to tip over

Pipettes Measures volume Used in transferring Left- gives a precise measurement at a set volume Right – gives a precise measurement at any volume

Volumetric Flask Measures a precise set volume Used to make solutions

Beaker Used for volume Not precise – “ball park” estimates only Very versatile

Graduated Cylinder Measures volume Accurate and precise Has a meniscus – the bottom curve of a liquid Read at eye level

Test Tube Stores and transfers small amounts of liquid

Test Tube Holder Holds test tubes for heating and moving purposes

Test Tube Rack Holds multiple test tubes at a time

Crucible Tongs Picks up crucibles and crucible tops ONLY

Crucible and Cover Used when heating chemicals at very high levels

Ring Clamped to a ring stand to support glassware

Bunsen Burner Heats objects Placed under the ring on a ring stand

Ring Stand Supports rings used to heat or hold glassware

Watch Glass Covers beakers Evaporates small amounts of liquids

Wire Mesh Supports beakers on a ring stand

Funnel Used when pouring large amounts of liquids Can be lined with filter paper and used to strain to solutions

Petri Dish Grows bacteria cultures

Goggles Eye protection Worn at all times in the laboratory

Lab Apron Protects clothing from spills and chemical splashes

Gloves Protects hands and skin from chemicals

Thermometer Measures temperature

Scalpel Cuts into specimens during dissection Very sharp

Forceps Pulls apart the skin and organs during dissection NOT tweezers

Eye Dropper Inaccurate Drips very small amounts of liquid

Clay Triangle Allows crucibles to sit over a Bunsen Burner Typically placed on a ring attached to a ring stand

Triple Beam Balance Measures the mass of an object

Microscope Slides Holds the specimen over the light on a microscope

Cover Slips Covers the specimen on a microscope slide

Microscope Allows a small specimen to be viewed under magnification
