Common Laboratory Equipment

Overview of standard apparatus and tools used in a chemistry laboratory, including glassware, heating devices, and measuring instruments.

Beaker

Glass or plastic; common sizes are $50\,\text{mL}$, $100\,\text{mL}$, $250\,\text{mL}$, and $400\,\text{mL}$; glass beakers may be heated.

Buret

Glass; common sizes are $25\,\text{mL}$ and $50\,\text{mL}$; used to measure volumes of solutions in titration.

Ceramic Square

Used under hot apparatus or glassware.

Erlenmeyer Flask

A cone-shaped glass laboratory flask with a narrow neck and flat bottom used for holding and mixing liquids.

Florence Flask

A round-bottomed laboratory flask with a long neck designed for uniform heating and boiling of liquids.

Graduated Cylinder

A tall, narrow cylindrical container marked with a scale used for measuring liquid volumes.

Volumetric Flask

A flat-bottomed glass flask calibrated to contain a precise volume of liquid at a specific temperature.

Condenser

A glass apparatus used to cool gas or vapor, converting it back into a liquid during distillation processes.

Platform Balance (Triple Beam)

A mechanical balance scale used to measure mass accurately.

Stirring Rod with Rubber Policeman

A glass rod fitted with a flexible rubber tip used for stirring liquids and scraping chemical residues from container walls.

Clay Triangle

A wire frame covered with clay tubes, placed on a ring stand to support a crucible during heating.

Wire Gauze

A sheet of thin wire mesh used to support glassware on a ring stand and evenly distribute flame heat.

Mortar and Pestle

A ceramic vessel and heavy grinding tool set used to crush solid substances into fine powder.

Crucible and Cover

A small heat-resistant ceramic cup and lid used to heat chemical compounds to very high temperatures.

Scoopula

A curved metal utensil used to transfer small amounts of solid chemical reagents.

Beaker Tongs

Tongs designed specifically with shaped jaws to grip and move hot beakers safely.

Crucible Tongs

Tongs with bent tips designed for handling hot crucibles and their lids.

Test Tube Holder

A clamp-style tool used to securely hold individual test tubes during heating or reactions.

Evaporating Dish

A small ceramic bowl with a spout used to evaporate excess solvent from chemical mixtures.

Plastic Wash Bottle

A flexible squeeze bottle used to dispense controlled amounts of liquid to rinse laboratory glassware.

Test Tube Brush

A wire-handled bristle brush designed to clean test tubes and narrow glassware.

Watch Glass

A circular concave glass dish used as a surface for evaporating liquid, holding solids, or covering beakers.
