1)Cryotube with external screw cap is designed for freezing samples,The external screw cap design can reduce the contamination probability during sample treatment.
2)Cryotube 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)Transparent tube for easy observation.
5)Round bottom design is good for pouring liquids out with little residual.
