Lab Equipment Overview

Lab Equipment

Pipette

  • Measures liquids to a precise 25 cm³.

  • Pros: Accurate.

  • Cons: Slower than measuring cylinder.

Burette

  • Measures liquids up to 50 cm³.

  • Pros: More accurate than measuring cylinder.

  • Cons: Slower to empty.

Measuring Cylinder

  • Available in 25, 50, 100, 250 cm³.

  • Pros: Easy and quick to use.

  • Cons: Less accurate than pipettes and burettes.

/

Conical Flask

  • Holds and measures liquids; good for mixing.

  • Pros: Easy to mix.

  • Cons: Difficulty in swirling compared to beaker.

Beaker

  • Holds, mixes, and heats liquids.

  • Pros: Versatile for various tasks.

  • Cons: Harder to mix than conical flask.

Dropper (Teat Pipette)

  • Adds liquids drop by drop.

Gas Jar

  • Collects gases.

Trough

  • Holds liquid for collecting gases over water.

Mortar and Pestle

  • Used to grind solids into smaller pieces.

Crucible

  • Melts or heats solid chemicals at high temperatures.

Round/Flat Bottomed Flasks

  • Used for heating liquids (distillation)

Volumetric Flask

  • Prepares solutions to an exact volume.

Gas Syringe

  • Collects and measures gas volumes.

Evaporating Dish

  • Used for evaporation of solutions.

Thermometer

  • Measures temperature in solids, liquids, and gases.

Watch Glass

  • For evaporation, weighing, and as a lid.

Top Pan Balance

  • Measures mass accurately.

Stopwatch

  • Measures time intervals.

Stopper Cork / Bung

  • Seals openings of glassware to prevent gas/ liquid escapes.

Gauze

  • Distributes heat from flame evenly.

Tripod

  • Supports glassware above the Bunsen burner.

Bunsen Burner

  • Produces flame for heating.

Funnel/Separating Funnel

  • Separates solids from liquids, or immiscible liquids.

Test Tube Holder/Rack

  • Holds test tubes when heating or multiple tubes upright.

Spatula

  • Transfers small solid quantities.

Condenser

  • Cools and condenses vapor to liquid.

Fractionating Column

  • Separates liquid mixtures based on boiling points.

Goggles

  • Protects eyes from harmful substances.

Delivery Tube

  • Transfers gases between containers.

Experimental Precautions

  • Wear gloves/goggles for strong acids and alkalis.

  • Keep flammable substances away from flames.

  • Use fume cupboard for toxic gases.

  • Use electrical heaters for flammable liquids instead of open flames.
