Laboratory Container Apparatus

Basic Information About Common Laboratory Apparatus

Laboratory apparatus are essential tools used in scientific experiments. They help in measuring, heating, mixing, and storing chemicals. Below are some common laboratory containers and their functions.

Apparatus Used as Containers in the Laboratory

1. Beaker

📌 Used to dissolve, mix, and heat large amounts of liquids. It has a wide opening for easy pouring and stirring.

2. Test Tube

📌 A reaction vessel for experiments with small amounts of reactants. Commonly used for chemical reactions and heating.

3. Flask (200 ml)

📌 Functions as a reaction vessel, gas generator, and liquid holder. Suitable for heating solutions safely.

4. Volumetric Flask

📌 Used for accurate dilution and preparation of precise solution volumes. Essential for quantitative experiments.

5. Evaporating Dish

📌 Helps in evaporating liquids, leaving behind solid materials. Commonly used in crystallization experiments.

6. Watch Glass

📌 Used for spontaneous evaporation, weighing small amounts of substances, and covering beakers.

7. Mortar and Pestle

📌 Essential for grinding solid materials into fine powder, improving solubility and reactivity.

8. Crucible

📌 A heat-resistant container used for high-temperature ignition of substances, commonly in combustion and decomposition reactions.

Conclusion

Laboratory apparatus plays a vital role in scientific research, chemical reactions, and sample preparation. Understanding their functions ensures safe and efficient laboratory work.

Apparatus used for Measuring in the Laboratory

Apparatus Used For Measuring In The Laboratory

Here are the apparatus used for Measuring in the Laboratory:

1.      Balance and Weights – this is used to weigh materials in the laboratory.

2.      Buret – this is a graduated glass tube used in volumetric analysis for measuring definite and accurate amount of liquid.

3.      Graduated Cylinder – a cylinder closed at one end and calibrated in the Metric system; used to measure the amount of liquid sample, never use it as a reaction vessel.

4.      Dropper or pipettes – this is used to transfer / measure small amount of liquid samples.

5.      Spatula – this is used to remove or scoop out solids from the container.

6.      Thermometer – this is used to measure temperature, in Degree Celsius (⁰C) or Degree Fahrenheit (⁰F).

Apparatus used for holding and holding things in the Laboratory

Apparatus Used For Holding And Holding Things In The Laboratory

Listed below are the apparatus used for holding and holding things in the Laboratory:

1.      Clamps – this is used to support test tubes, flasks, burets, etc.

2.      Clamp Holder – this is used to hold clamp in its proper position.

3.      Funnel – this supports the filter paper and facilitates the introduction of liquid to prevent spilling.

4.      Iron Ring – this is mounted on an iron stand to support beakers, flasks, etc.

5.      Iron Stand or Ring Stand – this is used to mount apparatus.

6.      Test Tube Holder – this is used to hold test tube while heating and when working with corrosive reagents.

7.      Tripod – this is to support apparatus which does not have to be attached.

8.      Test Tube Rack – this is used to keep a supply of test tubes for use.

Apparatus used for heating in the Laboratory

Apparatus Used For Heating In The Laboratory

Hereunder are the apparatus used for heating in the Laboratory:

1.      Bunsen burner – this is used as a source of heat in the laboratory.

2.      Pipe Stem or Clay Triangle – this is used to support the crucible while heating.

3.      Wing Top or Fish Tail – this is placed over the barrel of a burner to spread the flame.

4.      Wire Gauze or Asbestos Pad – this is used to separate beaker and flask from direct heat of the burner.
