  • Test Tube - Used for most experiments using some form of liquid. They have a bung that goes on the top to seal it.
  • Conical Flask - Used for experiments with liquid up to 150 mL. The Flask has a rubber bung for the top and the glass is heatproof.
  • Glass Stirring rod - A 20cm rod used for stirring and mixing any type of chemicals or liquid.
  • Test tube tongs - Used for holding hot Test Tubes after an experiment.
  • Spatula - For holding very small amounts of chemical powders.
  • Funnel - Used for adding chemicals and liquid into a beaker or etc so it doesn't spill everywhere.
  • Measuring Cylinder - Used to measure liquids for experiments. The liquid will be poured into the beaker or etc to measure the right amount so you can put it into a beaker later on.
