Beaker Tongs

Safely move a hot beaker without touching it.

Flint Striker

Produces a spark to light a Bunsen burner.

Crucible Tongs

Specially shaped to hold and move very hot porcelain crucibles.

Crucible

Heats solid chemicals to very high temperatures so they will combust.

Buret Clamp

Attaches a buret to a ring stand for support.

Pipettes

Measure out accurate amounts of solutions and transfer them between containers.

Graduated Cylinder

Tall, narrow container with measurements used to accurately measure solutions.

Test Tube

Holds a small amount of liquid chemical to be tested, heated, or observed.

Thermometer

Measures temperature or average kinetic energy.

Stirring Rod

Stirs solutions, places drops on pH paper, and assists in pouring chemicals.

Weigh Boat

Holds and transfers small amounts of solid chemicals on an electronic balance to prevent contamination.

Wire Mesh (Wire Gauze)

Platform with a ceramic center for a beaker to be heated over a Bunsen burner.

Lab Tweezers

Small tools to pick, lift, move, and grab small particles and delicate samples.

Funnels

Used to pour liquid chemicals into smaller containers safely.

Bunsen Burner

Produces a hot blue flame from gas to heat or burn chemicals.

Beaker

Holds and heats liquids; not good for accurate measurements.

Volumetric Flask

Used to mix specific concentrations of chemicals up to a fill line.

Well Plate

Performs micro scale experiments side by side to compare multiple trials.

Test Tube Racks

Holds several test tubes next to each other for observation.

Spatulas (Scoopulas)

Long, thin metal scoops used to move small amounts of solid chemicals.

Buchner Funnel

Used with an Erlenmeyer flask and aspirator for vacuum filtration.

Erlenmeyer Flasks

Flasks with a wide flat bottom used in filtration and for holding stoppered chemicals.

Clay Triangle

Metal and clay device used to suspend a crucible over a Bunsen burner.

Ring Clamp

Attaches to a ring stand to support a clay triangle or wire gauze.

Test Tube Holder

Wire spring clamp that holds a test tube so you do not have to touch it.

Watch Glass

Concave glass surface used to evaporate liquids, weigh solids, or cover beakers.

Electronic Balance

Scale that measures material weight electronically (less precise than an analytical balance).

Analytical Balance

Highly precise measuring instrument to determine mass of small samples.

Ring Stand

Heavy base and tall pole used to attach clamps for titrations and heating.

Evaporating Dish

Small porcelain container used to allow small amounts of liquid to evaporate.

Burette

Long narrow tube with a spigot used to accurately measure solution added during titrations.

Mortar and Pestle

Hard bowl and rod used to grind or crush solids into finer pieces.

Desiccator

Storage device to keep chemicals in a very low humidity environment.
