Factory Direct: Premium Internal & External Screw Cap Tubes and Cryogenic Vials

Standard Screw Caps are low profile caps fitted with ethylene propylene sealing o-rings. Screw Cap II is manufactured from polypropylene and fitted with a silicon o-ring. Tether (loop) Caps are low profile caps with a molded tether and a ethylene/propylene sealing o-ring. Tether (loop) Cap II is molded with a tether (or loop) which easily and securely fits onto the tube, keeping the cap always with the tube. 1) Cryo tube with external screw cap is designed for freezing samples,The external screw cap design can reduce the contamination probability during sample treatment. 2) Cryo tube with internal screw cap is for freezing samples in gas situation of liquid nitrogen. The silicone gel o-ring can enhance the sealing performance of the tube. 3) The caps and tubes are all made of PP material with same batch and mode. Thus same dilatation coefficient can ensure the tube sealing performance under any temperature. 4) Large white writing area allows easy marking. 5) Transparent tube for easy observation. 6) Round bottom design is good for pouring liquids out with little residual.

Polypropylene material, inside spin and outside spin can be selected. The tube wall has calibration and marking area for sample marking. Y ray sterilization, no DNA enzyme, no RNA enzyme. Can be placed in liquid nitrogen tanks. Caution, using properly cryopreservation methods and do not place cryopreservation tubes in liquid nitrogen. If improperly stored, liquid nitrogen remaining in cryopreserved tubes can result in explosion or release of biohazard materials due to liquefaction.
