Pack of five 10ml transparent screw-capped test tubes with a flat bottom.
Pack of five 10ml plastic test tubes. These screw-capped tubes are transparent so you can see exactly whats inside. Their flat bottom allows them to stand-up on flat surfaces without the need for a test tube rack. Fill them with different liquids, like oil, water, vinegar, glycerol and food dye, for identification through shaking and tipping. An essential teacher resource for any science classroom.
