In a school lab, various types of glassware are commonly used for different scientific experiments and measurements. Here is a list of some commonly used glassware in a school laboratory:

Beaker: Used for holding, mixing, and heating liquids.

Erlenmeyer flask: Similar to a beaker, but with a conical shape and a narrow neck. Used for swirling liquids and titrations.

Test tube: Small, cylindrical tubes used for holding small amounts of liquids or conducting small-scale experiments.

Graduated cylinder: Tall, narrow cylinders with calibrated markings used for accurate measurements of liquid volumes.

Pipette: Used for transferring small volumes of liquids. They come in various sizes, such as micropipettes and volumetric pipettes.

Burette: A long, graduated tube with a stopcock at the bottom. Used for precise dispensing of liquids during titrations.

Petri dish: Shallow, circular glass or plastic dishes with covers. Used for culturing microorganisms or observing small specimens.

Watch glass: Concave glass dish with a slight lip. Used as a cover for beakers or for evaporating small amounts of liquid.

Funnel: Used for pouring liquids or transferring substances into containers with smaller openings.

Conical flask: Also known as a filtering flask, it has a conical shape with a narrow neck. Used for filtration and vacuum experiments.

Mortar and pestle: Used for grinding and pulverizing solid substances into finer powders.

Glass stirring rod: Long, thin glass rod used for stirring liquids or manipulating solid substances.

Dropper bottle: Small glass bottle with a built-in dropper. Used for dispensing small quantities of liquid reagents.

Glass slide: Thin, flat piece of glass used for mounting and observing specimens under a microscope.

Cover slip: Small, thin piece of glass used to cover specimens on a microscope slide.

Centrifuge tube: Small, cylindrical tube with a conical bottom used for separating substances through centrifugation.

Distillation apparatus: Consists of a distilling flask, condenser, and collection flask. Used for separating mixtures based on boiling points.

Desiccator: A sealed container with a drying agent (such as silica gel) used to store substances in a dry environment.
