Laboratory apparatus names and ther use?

Answer 1

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 burners
