Tools And Their Uses

Tools and their uses: beaker - a liquid-measuring container burette - measures volume of solution clay triangle - a wire frame with porcelain used to support a crucible wire gauze - used to spread heat of a burner flame test tube - used as holder of small amount of solution forceps - holds or pick up small objects graduated cylinder - measures approximate volume of liquids graduated pipette - measures solution volumes condenser - used in distillation crucible - used to heat a small amount of a solid substance at a very high temperature funnel - used to transfer solids and liquids without spilling thermometer - measures temperature balance - measures mass of material pH meter - measures acidity of solutions centrifuge - separates materials of varying density pipette - used to transfer measured substances into another vessel droppers - for addition of liquids, drop by drop glass funnels - for funneling liquids from one container to another, or for filtering when equipped with filter paper. graduated cylinders - for measurement of an amount of liquid. The volume of liquid can be estimated to the nearest 0.1 mL with practice. ring stand (with rings or clamps) - for holding pieces of glassware in place. test tubes - for holding small samples or for containing small-scale reactions test-tube holders - for holding test tubes when tubes should not be touched tongs - similar function to forceps, but are useful for larger items volumetric flasks - to measure precise volumes of liquid or to make precise dilutions. wash bottles - for dispensing small quantities of distilled water. watch glasses - for holding small samples or for covering beakers or evaporating dishes. wire gauze on a ring - supports beakers to be heated by Bunsen burners
