Q & A

What is the function of a measuring flask in the laboratory?

A measuring flask is used for dilution of solutions and for preparing solutions in the laboratory.

What are the main uses of a test tube in the lab?

A test tube is used for mixing, containing, and heating both liquid and solid chemical substances, primarily for qualitative testing.

How is a beaker used in the laboratory?

A beaker is typically used for mixing, measuring, and storing liquids in a laboratory.

What is the purpose of a dropper in laboratory procedures?

A dropper is used to transfer a small, measured amount of liquid, usually in the form of drops, from one container to another.

What distinguishes a volumetric pipette from other types of pipettes?

A volumetric pipette is used to transfer a specific volume of liquid accurately, typically with a high level of precision.

What is the function of a tripod stand in the laboratory?

A tripod stand is used to support a wire gauze or container during heating, providing stability for lab apparatus.

What is the role of a clamp in laboratory work?

A clamp is used to hold test tubes and other apparatus securely, especially during heating or other experimental procedures.

What is the primary function of a wire gauze in the laboratory?

A wire gauze is used to support containers such as beakers or flasks during heating, preventing direct contact with the heat source.

Why is a condenser important in distillation?

A condenser cools hot vapors during distillation, allowing them to condense back into a liquid form.

What is the purpose of an evaporating dish in a laboratory?

An evaporating dish is used to heat substances, usually liquids, to evaporate the solvent, leaving behind solid material.
