Laboratory test tube T342T - SNAPTWIST™ MICREWTUBE®

polypropylenemicrocentrifugewith screw cap

Tube made of polypropylene RNase, DNase, Pyrogen and DNA-free Temperature range: -90°C to +100°C Tubes only The SnapTwistTM Micrewtube® provides all the advantages of a modern microcentrifuge tube with screw cap but the closure is a true time saver. The SnapTwistTM Micrewtube® has a multitude of applications around your lab. It is ideal for freezer storage, boiling application, centrifugation etc, and will fit most standard microcentrifuge rotors. Manufactured of exceptionally high-quality, transparent polypropylene without the use of slip agents, plasticizers, mold release agents and biocide substances. The tubes can be securely sealed by simply capping the closures on. Removal of caps requires an easy 1/4 turn (twist). The ease with which these caps can be manipulated eliminates the danger of spillage associated with other push-on/pull-off caps. The deep internal lip of the cap fits snugly against the interior wall of the tube preventing the contents from coming in contact with the threads, thus reducing the chances of sample contamination. The quality of the sealing system is such that it is not necessary to tighten the closure with pressure to achieve a leakproof seal. This series of tubes is not available with graduations. Caps cannot be autoclaved since they are made of high density polyethylene. Conical bottom tubes can be centrifuged up to 20,000g. Temperature range: -90 °C to +100 °C. Skirted tubes can be centrifuged up to 17,000g.
