Test Tubes

Glass laboratory tubes made of borosilicate glass are ideal for chemical reactions, cultures, or sample heating due to their high thermal and chemical resistance. Our range covers reagent and microbiological tubes with round or conical bottoms, rimmed or straight-walled, as well as centrifuge tubes and models with glass stoppers or screw caps. Do you need durable tubes for heating over a burner or do you prefer glass over plastic for working with organic solvents? Find the right size and type of glass tube here.
