Here are 20 Laboratory apparatus and Their uses in Detailes:

1). Beaker

I) A cylindrical container with a flat bottom, used for mixing, heating, and holding liquids.

II) Available in different sizes, often made of glass or plastic.

III) Has measurement markings but not very precise for measuring volumes.

2) Erlenmeyer Flask (Conical Flask)

I) A flask with a narrow neck and wide base, used for mixing and heating liquids without spilling.

II) Ideal for titration and chemical reactions that require swirling.

3). Test Tubes

I) Small glass tubes used for holding, mixing, or heating small amounts of substances

II) Can be used for qualitative experiments, chemical reactions, and microbiology cultures.

4). Graduated Cylinder

I) A tall, narrow cylinder with markings used for precisely measuring liquid volumes.

II) More accurate than beakers for liquid measurement.

5). Pipette

I) A tool used for transferring precise amounts of liquid.

II) Types include graduated pipettes, micropipettes, and volumetric pipettes.

6). Burette

I) A long, graduated tube with a stopcock used for accurate liquid dispensing, especially in titrations.

II) Common in acid-base titration experiments

7). Volumetric Flask

I) A flask with a long neck and a precise volume marking used for preparing accurate solutions.

II) Essential for making standard solutions.

8). Funnel

I) A cone-shaped tool used for transferring liquids into containers with small openings.

II) Used in filtration when paired with filter paper

9). Filter Paper

I) A special paper used for separating solids from liquids in filtration.

II) Often used in gravimetric analysis.

10). Mortar and Pestle

I) A tool used for grinding and mixing solid substances into fine powders.

II) Essential in pharmaceutical and chemical laboratories.

11). Crucible and Lid

I) A small ceramic or metal container used for heating substances at very high temperatures.

II) Used in melting, drying, and chemical decomposition experiments.

12). Watch Glass

I) A circular, concave piece of glass used for holding small amounts of substances.

II) Can also be used as a cover for beakers.

13). Test Tube Holder

I) A clamp-like tool used for holding test tubes while heating or handling hot tubes.

II) Prevents burns and spillage.

14). Wire Gauze

I) A mesh placed over a Bunsen burner flame to distribute heat evenly.

II) Supports glassware during heating.

15). Bunsen Burner

I) A gas-powered device used for heating chemicals and substances.

II) Produces an adjustable flame for different heating requirements.

16). Tripod Stand

I) A three-legged stand used to support beakers, flasks, or crucibles during heating.

II) Usually used with a wire gauze.

17). Thermometer

I) Measures temperature in experiments, available in mercury, alcohol, or digital versions.

II) Important for controlling reaction conditions.

18). pH Meter

I) An electronic device used for measuring the pH (acidity or alkalinity) of solutions.

II) More accurate than pH indicator papers.

19). Hot Plate

I) An electrical heating device used as an alternative to Bunsen burners for controlled heating.

II) Often used for heating substances without an open flame.

20). Centrifuge

I) A machine that spins samples at high speed to separate substances by density.

II) Used in blood analysis, DNA extraction, and chemical separations.
