These disposable sterile tubes are made of high quality polypropylene (PP) that will withstand temperatures from -190o to +120oC. They are also available in crystal clear polystyrene (PS) with more limited range of 0o to 70oC. Caps are made of polyethylene (PE) and have the popular two position design (up/loose for aerobic work and down/sealed for anaerobic cultures). Polystyrene tubes may be centrifuged at up to 2000g. Polypropylene tubes withstand higher forces up to 4000g.
