Takeaways

• 😀 Always wear proper protective gear before entering the lab: laboratory coat, gloves, face mask, and shoes made of thick material.
• 😀 Laboratory tools include TDS meters, PH meters, mortars and pestles, porcelain cups, glass spatulas, and many more.
• 😀 A glass beaker is used to measure volume and store or heat solutions that do not require high accuracy.
• 😀 A measuring flask is used for making and diluting solutions with high accuracy, by filling up to the marked limit and shaking to mix the solution.
• 😀 An Erlenmeyer flask is used for mixing, measuring, and storing liquids, and it is shaken using a rotating motion for proper mixing.
• 😀 Petri dishes are used for cell culture, while porcelain cups are used for evaporating non-volatile materials.
• 😀 A mortar and pestle are used to crush or smooth solid or crystalline substances.
• 😀 A burette is essential for titration with high precision, and it measures the volume of a solution in titration processes.
• 😀 A thermometer is used to measure temperature changes in substances, typically filled with mercury or alcohol.
• 😀 Always clean laboratory tools after use with running water, soap, and drying them properly.

Q & A

What is the first thing you must wear before entering the laboratory?

Before entering the laboratory, you must wear a laboratory coat, gloves, and a mask.

What is the purpose of wearing thick shoes in the laboratory?

Thick shoes are required to protect your feet from any potential chemical spills or accidents in the laboratory.

What equipment is typically used to measure the volume of solutions in the laboratory?

A glass beaker is used to measure the volume of solutions or materials that do not require high accuracy.

How do you use a measuring flask in the laboratory?

A measuring flask is used to make and dilute solutions with high accuracy. To use it, fill the flask with liquid up to the limit mark, then shake it slowly to ensure the liquid is perfectly mixed.

What is the function of an Erlenmeyer flask?

The Erlenmeyer flask is used to mix, measure, and store liquids. It is typically shaken with a rotating motion to mix the contents.

What is the purpose of using a mortar and pestle in the laboratory?

A mortar and pestle are used to crush or grind solid or crystalline substances into finer particles.

How do you use a digital pH meter?

To use a digital pH meter, place it into the solution or liquid and press the button to display the pH value on the screen.

What is the role of a burette in the laboratory?

A burette is used for titration with high precision. It is also used to measure the volume of a solution during experiments.

Why is it important to clean laboratory tools after use?

Cleaning laboratory tools is crucial to prevent contamination of future experiments. Tools should be cleaned with running water and soap, then rinsed and dried properly.

What is the function of a TDS meter in the laboratory?

A TDS meter is used to measure the total dissolved solids (TDS) in a liquid or solution, which gives an indication of its purity or concentration.
