Scientific Lab Equipment Quiz

Scientific Lab Equipment

• Beaker: Used for pouring, storing, mixing, heating, and dispensing. Not used for accurate measurement. It has a beak to aid pouring.

• Flask: Used to hold solids or liquids, that may release gases during a reaction or might splatter when stirred or heated.

• Florence Flask: Used to hold liquids, not accurate measurements.

• Volumetric Flask: A laboratory flask calibrated to hold a precise volume at a specified temperature. Used for precise dilutions and preparing standard solutions. Typically pear-shaped with a flat bottom, and made of glass or plastic.

• Graduated Cylinder: Used to measure liquids, not for reactions. Read measurement from the curve of the meniscus.

• Test Tubes: Used to hold liquids and chemicals during experiments. Used for storing, mixing, and heating. Not for measuring. Should be held with tongs or clamps, never by hand.

• Burette: Vertical cylindrical laboratory glassware. Used to dispense known amounts of liquid in experiments.

• Meniscus: The curved surface of a liquid in a container, caused by adhesion between the liquid and the container, and cohesion between liquid particles.

• Test Tube Holder: Used to hold test tubes that are too hot to handle.

• Test Tube Brushes: Used to clean test tubes and graduated cylinders.

• Test Tube Racks: Used for holding and organizing test tubes. Plastic racks may melt with extreme heat.

• Rubber Stoppers: Used to close containers to avoid spillage or contamination. Avoid heating containers while stoppers are in place.

• Spot Plates: Used for many small-scale reactions at one time.

• Watch Glass: Used to hold small amounts of solid, like reaction products.

• Glass Stir Rod: Used to manually stir solutions, and transfer one single drop of a solution.

• Stirring Rod: Used to mix chemicals or hot liquids together.

• Medicine Dropper (Eyedropper): Used to transfer small volumes of liquid (less than one mL).

• Litmus Paper: Used to identify bases (red litmus paper turns blue) and acids (blue litmus paper turns red).

• Funnel: Used to transfer liquids from one container to another.

• Mohr Pipet: Measures and delivers exact volumes of liquids.

• Micropipette: A laboratory instrument used to accurately and precisely transfer microliter volumes of liquids. Single-channel versus Multi-channel.

• Wash Bottle: Delivers wash solution to a specific area; distilled water only.

• Weighing Boat: Used to weigh solids that will be transferred to another vessel.

• Spatulas: Used to dispense solid chemicals from containers; chemicals should not be transferred with bare hands.

• Beaker Tongs: Used to move beakers containing hot liquids.

• Bunsen Burner/Hot Plate: Heat source. Bunsen burners heat non-volatile liquids and solids, hot plates use electricity.

• Ring Stand with Clamp and Ring: Holds containers away from heat during experiments.

• Iron Ring: Provide a stable, elevated platform for reactions.

• Utility Clamps: Used to secure test tubes, distillation columns, and burets to the ring stand.

• Double Buret Clamps: Used to hold burets (long graduated tubes used in titration).

• Laboratory Centrifuge: Equipment that spins liquid samples at high speed for separating substances of different densities.
