Micrewtubes Screw Cap Graduated Test Tubes with Tether Caps

These Micrewtubes Screw Cap Graduated Test Tubes with Tether Caps have a molded-in tether (leash and loop) that allows the cap to remain attached to the body of the tube whether the cap is open or closed. When attached to the screw cap microtube, the tether rotates freely for easy opening and closing. Tethered caps can be easily removed from the tubes if desired.

Natural polypropylene tubes and caps can withstand centrifugation to 17,000 x g, vapor phase liquid nitrogen storage, boiling, and autoclaving. Caps feature an O-ring to guard against leakage.

Tubes have printed graduations and white marking areas for sample identification and are gamma radiation sterilized, with tether caps attached and screwed onto the tubes. Packaged 50 tubes/caps per bag, 10 bags per case.
