These large, plastic centrifuge or test tubes are perfect for little hands to hold for cool coloured experiments. They measure 12cm long and 3.5cm in diameter, and can hold up to 50ml of liquid. Made from safe and durable, completely transparent polypropylene, these tubes have no graduations.
Hard-to-find jumbo tubes are ideal for a multitude of purposes including homemade mini lava-lamps, fizzing reactions, density tubes and special 'containers' or decorations for a science party or event. They come with a white screw top and have a tapered base, so you'll need to stand them on their lid if you want them upright.
