Simport Scientific Micrewtube with Washer Seal Screw Cap and Attachment Loop

The washer seal secured in the top of the cap ensures a positive leakproof seal, time after time, keeping the integrity of the small sample under even the most adverse conditions. 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.

Caps are supplied with attachment loops, allowing them to remain attached to the tube to prevent mix-up and contamination.

Perfect for cryogenic work. Non-skirted tubes can be centrifuged up to 20,000 x g. Skirted tubes can be centrifuged up to 17,000 x g. Will withstand temperatures from -196°C to +121°C.
