Test tubes
Test tubes are available in various shapes, for example with round, conical or straight bottom as well as with beaded or straight rim. Depending on the type, the test tubes are suitable for chemical reactions, examinations, for storing of small quantities of liquids, cultivation of bacteria and much more. The test tubes can be sealed with plastic foils, aluminium caps, cork or plastic stoppers, Please see the separate section on stoppers, closures and lids.
