Product Description

Our 1.8ml cryovials with external threads and a silicone washer seal are designed to give you complete peace of mind. These aren’t your average cryovials! The external thread design means the threads are on the outside of the vial, so there’s less chance of your sample accidentally touching them and getting contaminated.

Cryovials are the ideal lab consumables for biological sample storage. In the gas situation of liquid nitrogen, it can withstand temperatures as low as -196ºC. The silicone gel O-ring in the cap ensures no leakage, even at the standard lowest storing temperature, which will guarantee the sample’s safety.

Cryovial with external screw cap is designed for freezing samples,
The external screw cap design can reduce the contamination probability during sample treatment.
Cryovial with internal screw cap is for freezing samples in the gas situation of liquid nitrogen.
The silicone o-ring can enhance the sealing performance of the tube.

What is cryovials tube?

A cryovial tube is a small, specialized container designed for storing biological samples at extremely low temperatures. These tubes are essential for cryopreservation, maintaining sample integrity in conditions like liquid nitrogen vapor or ultra-low temperature freezers.

Are 1.8ml cryovials with external threads leakproof?

Yes, 1.8ml cryovials with external threads, especially those featuring a silicone washer seal, are designed to be completely leakproof. The combination of the external thread and the silicone washer creates a tight, secure seal that prevents leakage even at cryogenic temperatures.

Are cryogenic vials leakproof at -196°C?

High-quality cryogenic vials, especially those with an external thread and a well-designed cap, are engineered to be leakproof even at the extremely low temperatures of liquid nitrogen vapor phase storage (-196°C). Reputable manufacturers perform rigorous testing to ensure the integrity of the seal. Look for vials made from medical-grade polypropylene.

Can I use 1.8ml external thread cryovials in liquid nitrogen vapor phase?

Yes, 1.8ml external thread cryovials are specifically designed for use in the vapor phase of liquid nitrogen (down to -196°C). The medical-grade polypropylene construction and the secure seal ensure the vial’s integrity and the sample’s safety.
