What are all the laboratory apparatus and their uses?
Laboratory apparatus are the tools required to complete lab work, including test tubes, pipettes, beakers, and graduated cylinders.
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
