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.
