Used in making solutions and dilutions. Pipets PIPETS.jpg Used to measure precise quantities very accurately. Used in making solutions and dilutions. Pipet Bulb PIPET BULB.jpg Used to pull a liquid into a pipet. NEVER use your mouth to do this. Graduated Cylinder Measure volumes of liquids. graduated Dropper Pipette Transfers small volumes of liquids. pipette Buret A buret is used to deliver solution in precisely-measured, variable volumes. Primarily used for titration, to deliver one reactant until the precise endpoint of the reaction is reached. buretsm buret3 Test Tube May be heated Mix chemicals Point it AWAY from others and yourself when heating http://www.labdepotinc.com/shop/shopdisplayproducts.asp?id=137& cat=Test+Tube%2C+KG%2D33+Glass+Tubing 45042 http://www.labdepotinc.com/shop /shopdisplayproducts.asp?id=130&cat=Test+Tube%2C+Culture%2C+Disposable 73500 http://www.labdepotinc.com/shop/shopdisplayproducts.asp?id=139&cat=Test+Tube%2C+Glass%2DStopper ed 45100 Test Tube Clamp DUHHHHH It holds a test tube Always use when heating test tubes testtubeclamp Test Tube Holder Holds test tubes in a vertical position. Allows for clear sight. Drying rack t-rack1 Evaporating Dish Holds small volumes of liquids being evaporated. evapdish Crucible Tongs Pick up and hold small hot items. crucibletongs Beaker Tongs BEAKER TONGS.jpg Pick up and hold hot beakers. Ring Stand Multi-purpose, mostly used as a support to heat chemicals and hold burets. ringstand UtilityClamp Clamps to ring stand on one side. The other side can hold test tubes, burets, flasks, condensers and other cylindrical lab apparatus. ringclamptesttube Ring One side clamps to ring stand. Place wire gauze on ring and it will hold beakers and flasks for heating. Can hold small beakers in place to prevent spilling. ironring_JPG Clay Triangle Supports a crucible for heating in a ring stand apparatus . Supports a funnel during filtering in a ring stand apparatus . _007claytriangle Funnel Holds filter paper for filtering solutions. Use when transferring liquids to smaller narrow necked containers. funnel Crucible and Lid Holds small amounts of chemicals for heating at high temperatures. cruciblelid Wire Gauze Spreads the heat produced by a Bunsen burner wiregauze Bunsen Burner Controls release of natural gas for burning. Surgical tubing connects to gas source. Flint used to ignite the burner BunsenBurner Igniter IGNIGHTER.jpg Used to light a Bunsen burner. Hot Plate hotplate.PNG Allows you to heat a solution without using an open flame. Mortar and Pestle Use to crush solid chemicals into fine powders. other_mortarpestle_sm Plastic Wash Bottle Dispenses distilled or de-ionized water for rinsing equipment. plastic-wash-bottle Pinch Clamp PINCH CLAMP.jpg Used to control the flow of liquids through tubing. Spatula Used to transfer solid chemicals. scoop Triple Beam Balance TRIPLE BEAM BALANCE.jpg Used to determine the precise mass of an object accurately. Electronic Balance ELECTRONIC BALANCE.jpg Used to determine the precise mass of an object accurately. Technology VERNIER.jpg Used to measure temperature, pH, voltage, pressure and a variety of other variables.
