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
