Laboratory apparatus are 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 and beakers that should not or cannot be touched.
Test tubes - for holding small samples or for containing small-scale reactions.
Test tube stands - for keeping a few test tubes upright
Droppers - for adding a very small amount of liquid, drop by drop
Burettes - for adding a precise volume of a liquid
Pipettes - to dispense small and precise amount of liquid samples
Bunsen burners, hot plates, hot water baths - heat sources
Beakers, Erlenmeyer flasks - to contain reactions or to hold liquid samples
Watch glasses - a cover for beakers; sometimes used 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 distilled water
Wire gauges, clay triangles - to support a container while it is heating
Clamp stands - to support a piece of equipment or a part of it that 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
