Give 30 laboraory apparatus and its function?

Answer 1

#Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations.

#Bunsen burners are sources of heat.

#Burets are for addition of a precise volume of liquid. The volume of liquid added can be determined to the nearest 0.01 mL with practice.

#Clay triangles are placed on a ring attached to a ring stand as a support for a funnel, crucible, or evaporating dish.

#Droppers are for addition of liquids drop by drop

#Erlenmeyer flasks are useful to contain reactions or to hold liquid samples. They are also useful to catch filtrates.

#Glass funnels are for funneling liquids from one container to another or for filtering when equipped with filter paper.

#Graduated cylinders are for measurement of an amount of liquid. The volume of liquid can be estimated to the nearest 0.1 mL with practice.

#Pipets are used to dispense small quantities of liquids.

Ring stand with rings or clamps are for holding pieces of glassware in place.

#Test tubes are for holding small samples or for containing small-scale reactions.

#Test tube holders are for holding test tubes when tubes should not be touched

#Tongs are similar in function to forceps but are useful for larger items.

#Volumetric flasks are used to measure precise volumes of liquid or to make precise dilutions.

#Wash bottles are used for dispensing small quantities of distilled water.

#Watch glasses are for holding small samples or for covering beakers or evaporating dishes.

#Wire gauze on a ring supports beakers to be heated by Bunsen burners

Answer 2

• Some equipment is used for containing substances. Beakers, vacuum boxes and flasks are examples of this.
• Examples of measuring equipment are thermometers, pressure gauges, scales, Newtometers and litmus paper. This also includes some of the stranger pieces of glass-wear, like the graduated dropper used for titration.
• Labs generally have a lot of things about for safety, such as goggles, heat proof mats and tongs.
• For most labs a computer is needed to analyse data.
• Some labs use optical apparatus like cameras, telescopes, filters, diffraction gratings and light boxes.
• If temperature is involved in the experiments then insulated boxes, heat/cool water baths, fridges, freezers and bunsen burners may be used.

Answer 3

conical flask 1. Beaker = a liquid-measuring container

2. Barrette = 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

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
testube holder- holds hot testubes
