Glassware and Equipment in Chemistry Laboratory

• Test Tube: A common laboratory glassware item, resembling a finger-like tube of glass or plastic. Used for mixing chemicals, holding liquids, heating liquids and collecting substances like blood and semen.

• Beakers: Containers used for holding liquids and solids, available in various sizes; markings are not always precise.

• Erlenmeyer Flask: Used for a variety of laboratory applications, including heating, mixing, storing and titrations. Volume markings are not always precise.

• Volumetric Flask: Used for measuring and storing solutions precisely. Has a marking indicating the exact volume.

• Graduated Cylinder: Used for transferring liquids with moderate accuracy. Marked with volume increments.

• Pipette: Used for precise transfer of liquids, with fixed volumes.

• Test Tube Holder: Holds test tubes, used when the tubes are hot or when they should not be touched directly.

• Test Tube Stand: Supports multiple test tubes upright simultaneously.

• Bunsen Burner: A small, adjustable gas burner used as a heat source in laboratories.

• Petri Dish: A shallow, round, cylindrical glass dish, used for culturing microorganisms and cells in laboratories.

• Tripod: A three-legged stand used to support flasks and beakers.

• Wash Bottle: A squeeze bottle with a nozzle used for rinsing laboratory glassware.

• Burette Clamp: Used to securely hold a burette on a stand. Useful in analytical chemistry tasks like titrations.

• Graduated Dropper (Pasteur Pipette): Used for transferring small quantities of liquid.

• Spatula: Small stainless steel utensil used to scrape, transfer or apply powders and pastes.

• Round-Bottom Flasks: Laboratory glassware with rounded bottoms, often used for chemical/biological procedures.

• Wire Mesh Gauze: Used for uniform heat distribution, often with or without a ceramic core.

• Glass Rod: Commonly used in laboratories to mix chemicals or liquids.

• Funnel: A tube used to guide liquids or powders, often with a narrow bottom. Various materials are available.

• Buchner Funnel: Specifically used for filtration. Commonly made of porcelain, but other materials are available.

• Clamp: Holds glassware, beakers, etc. Made of stainless steel.

• Test Tube Brush: Used for cleaning test tubes and narrow-mouthed glassware.

• Filter Paper: A semi-permeable paper barrier used for removing solids from liquids in labs.

• Separatory Funnel: Glassware used for separating liquids with different densities.

• Sample Containers: Used for storing chemicals, solid samples and transporting. Varieties exist, for example, Reagent Bottles, which hold liquids or powders.

• Watch Glass: A circular concave glass used for various tasks like evaporation of liquids, holding substances, and as lids for beakers.

• Mortar and Pestle: Implements to crush or grind materials.

• Desiccators: Used for keeping chemicals from absorbing moisture.

• Condenser: A piece of laboratory equipment for condensing substances in gaseous form to a liquid state.

• Crucible: A container of ceramic or metal, used to melt or subject substances to high temperatures.

• Mechanical Shaker: A device for mixing or agitating liquids or solids in a bottle or flask.

• Digital Balance: An instrument to weigh substances to the milligram level.

• Magnetic Stirrer: Used in laboratories for mixing liquids using a rotating magnetic field.

• Water Bath: A container holding heated water for heating or incubating samples.

• pH Meter: Used to measure the hydrogen-ion activity in a solution.

• Colorimeter: A device to measure the light absorption/transmission in a solution; helps estimate concentration.
