For chemistry experiments in the middle school science laboratory, test tubes are often a useful supply to have on hand. Glass test tubes can be used to store, heat and mix various chemicals and substances for chemistry labs. SKS Science offers several sizes of clear glass test tubes with black rubber lined caps. Styrene and polypropylene plastic test tubes are also available if more durable and shatter-proof test tubes are required, both of which have compatible stoppers, sold separately. In addition, we also offer a great selection of test tube racks to keep your samples and specimens safe and neatly organized.
