T336 Micrewtube® with Lip Seal Screw Cap and Attachment Loop

Tubes and caps in the Micrewtube^® Family are certified RNase, DNase, DNA, and Pyrogen free.  Closures are supplied in natural color. Will withstand temperatures from -196 °C to +100 °C. Non-skirted tubes can be centrifuged up to 20,000g. Skirted tubes can be centrifuged up to 17,000g. Perfect for cryogenic work. Manufactured of exceptionally high-quality, transparent polypropylene without the use of slip agents, plasticizers, mold release agents, and biocide substances.

The lip seal inside the cap ensures a positive leakproof seal under even the most adverse conditions. This deep internal lip 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. Lip seal caps cannot be autoclaved since the closure is made of high-density polyethylene. 

The attachment loop prevents contamination and mix-up.

This series of tubes are available either plain or with printed graduations and a white marking area for sample identification. The 0.5 ml model SPR only has a white marking area and is not graduated.
