Simport SnapTwist™ Micrewtube®

Supplier: SIMPORT SCIENTIFIC INC.
  • Conical bottom tubes can be centrifuged up to 20,000 g
  • Temperature range: -90°C to 100°C
  • Certified RNase-, DNase-, Pyrogen- and DNA-free
  • Tube made of polypropylene
  • Cap made of polyethylene

The SnapTwist Micrew Provides all the advantages of a modern microcentrifuge tube with screw cap but the SnapTwist closure is a true time saver. The SnapTwist Micrew 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.

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 leak proof seal.

This series of tubes is not available with graduations but caps are supplied with attachment loops in order to prevent contamination and mix-up. Caps cannot be autoclaved since they are made of high density polyethylene.
