The volume of liquid can be estimated to the nearest 0.1 mL with practice. 19.Test tubes - for holding small samples or for containing small-scale reactions 20.test-tube holders - for holding test tubes when tubes should not be touched 21.tongs - similar function to forceps, but are useful for larger items 22.volumetric flasks - to measure precise volumes of liquid or to make precise dilutions. 23.Wash bottles - for dispensing small quantities of distilled water. 24.Watch glasses - for holding small samples or for covering beakers or evaporating dishes. 25.Wire gauze on a ring - supports beakers to be heated by Bunsen burners The most common utensils and appliances that you need while performing hands on activities in a laboratory. The laboratory apparatus depends upon the type of laboratory you are in and the experiment you are going to perform. For example, if you are in a chemistry laboratory, the common apparatus you need to use are: Test tube holders, tongs - for holding test tubes, beakers etc. which should not or can not be touched. Test tubes - for holding small samples or for containing small scale reactions. Test tube stands - for keeping/standing a few test tubes Droppers - for addition of a very small amount of liquid, drop by drop. Burettes - for addition of a precise volume of a liquid. Pipettes - to dispense small and precise amount of liquid samples. Bunsen burners, hot plates, hot water baths - as heat source Beakers, Erlenmeyer flasks - to contain reactions or to hold liquid samples. Watch glasses - as a cover for beakers, or as an evaporating dish. Funnels - for funneling or for filtering. Graduated cylinders - to measure an amount of liquid. Volumetric flasks - to make precise dilutions. Wash bottles - for dispensing small quantities of distilld water. Wire gauges, Clay triangles - to support a container while heating. Clamp stands - to support an equipment/part of it which is otherwise unstable. Balances - to measure the mass of a reagent or product Kipps apparatus - to produce a reagent gas (e.g. H2S) in a controlled manner. Spectrophotometers - to measure the absorbance and transmittance of a liquid sample. Fume hoods - to ventilate harmful gases. Desiccators - to preserve a substance in a moisture free environment.
