Siny Plastic Internal Thread Tube Cryovials are precision-engineered for secure and reliable storage of biological samples at ultra-low temperatures. Made from high-quality polypropylene (PP), these cryovials are designed to withstand extreme conditions, including liquid nitrogen vapor (-196°C).

1. Cryovial with external screw cap is designed for freezing samples,
2. The external screw cap design can reduce the contamination probability during sample treatment.
3. Cryovial with internal screw cap is for freezing samples in the gas situation of liquid nitrogen.
4. The silicone o-ring can enhance the sealing performance of the tube.
5. Withstand max 20,000xg centrifugal force
