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
Kipp's 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.
