Duran Boiling Flasks: Test Tubes and Culture Tubes

Duran test tubes are thick-walled and therefore mechanically very resistant. Another advantage is that these test tubes still retain good thermal shock resistance.

DURAN® test tubes with DIN thread are also known as culture tubes. These culture tubes can be tightly closed using PBT screw caps. Hence, the tubes are particularly suited to the cultivation of micro-organisms or substance storage, etc. The contents only come into contact with the glass and PTFE seal.
