What are some laboratory apparatuses and their uses?

Answer 1

Laboratory Tools and Apparatuses

Tools include beakers, microscopes, tweezers, hot plates, lasers, volt meters, test tubes, Erlenmeyer flasks, thermometers, test tube racks, Bunsen burners, crucibles, tripods and more. They are used to measure, observe and gather data for experiments, as well as to safely perform reactions and to heat things. More advanced laboratory equipment includes items such as spectrometers, centrifuges and chromatographs.

Some Tools And Their Uses

Test tube For containing or heating small amount of substance

Boiling tube For containing and heating small amount o substance

Beaker For containing chemicals or collecting liquids

Conical flask For containing chemicals and collecting liquids

Round bottomed flask For preparation of gases if the process requires heating

Flat bottomed flask For containing chemicals when preparing gases if the process

requires no heating.

Measuring cylinder For measure of a volume to an accuracy of 1cm 3

Burette For measuring a volume of liquid to an accuracy of 0.1 cm3

Pipette For measuring very accurately a specific volume of liquid

Thistle funnel For transferring liquids into a flask

Tools and their uses:

1. beaker - a liquid-measuring container
2. burette - measures volume of solution
3. clay triangle - a wire frame with porcelain used to support a crucible
4. wire gauze - used to spread heat of a burner flame
5. test tube - used as holder of small amount of solution
6. forceps - holds or pick up small objects
7. graduated cylinder - measures approximate volume of liquids
8. graduated pipette - measures solution volumes
9. condenser - used in distillation
10. crucible - used to heat a small amount of a solid substance at a very high temperature
11. funnel - used to transfer solids and liquids without spilling
12. thermometer - measures temperature
13. balance - measures mass of material
14. pH meter - measures acidity of solutions
15. centrifuge - separates materials of varying density
16. pipette - used to transfer measured substances into another vessel
17. droppers - for addition of liquids, drop by drop
18. glass funnels - for funneling liquids from one container to another, or for filtering when equipped with filter paper.
19. graduated cylinders - for measurement of an amount of liquid. The volume of liquid can be estimated to the nearest 0.1 mL with practice.
20. ring stand (with rings or clamps) - for holding pieces of glassware in place.
21. test tubes - for holding small samples or for containing small-scale reactions
22. test-tube holders - for holding test tubes when tubes should not be touched
23. tongs - similar function to forceps, but are useful for larger items
24. volumetric flasks - to measure precise volumes of liquid or to make precise dilutions.
25. wash bottles - for dispensing small quantities of distilled water.
26. watch glasses - for holding small samples or for covering beakers or evaporating dishes.
27. wire gauze on a ring - supports beakers to be heated by Bunsen burner.
