High-Quality Sterile Cryo Vials for Liquid Nitrogen Storage – GMP Certified

Our Sterile Cryo Vials: Built for the Toughest Storage Challenges

When we set out to design our line of -196°C cryogenic storage tubes , we started by asking: What do researchers really need from a cryo vial? The answer was clear: durability, reliability, and flexibility. Here's how we deliver on each:

1. Premium Materials for Extreme Durability

We only use medical-grade polypropylene (PP) for our cryo vials. Why PP? Because unlike cheaper plastics, PP remains flexible even at ultra-low temperatures, resisting cracking during rapid temperature changes (like moving from liquid nitrogen to a warm lab bench). It's also chemically resistant, ensuring no interactions between the vial and your samples—critical for sensitive materials like enzymes or antibodies.

Every batch of PP resin we use undergoes rigorous testing to ensure it meets our strict standards for purity and performance. We reject any material with even minor impurities, because we know that a single speck of contamination could ruin your experiment.

2. Leak-Proof Design: The Silicone Gasket Difference

The most common complaint we hear about other cryo vials is leaks. That's why we invested in perfecting our seal design. Each of our vials features a leak-proof cryotube with silicone gasket —not the cheap rubber or foam gaskets you'll find in budget options. Silicone maintains its elasticity at -196°C, creating a tight, consistent seal every time you close the cap. We test each vial by submerging it in liquid nitrogen, shaking it, and then checking for leaks—only vials that pass this test make it to our customers.

We also offer both internal and external thread options to fit your lab's needs: Internal threads provide a lower profile, saving space in storage racks, while external threads are easier to open with gloves on (a big plus during busy lab days).

3. Pre-Sterilized for Ready-to-Use Convenience

No one has time to sterilize vials in-house, especially when working with tight deadlines. That's why all our cryo vials come pre-sterilized with either EO (ethylene oxide) or gamma radiation —your choice, depending on your lab's protocols. EO sterilization is ideal for heat-sensitive materials, while gamma sterilization offers a higher level of sterility assurance (SAL 10⁻⁶, the industry gold standard). Each vial is individually packaged in a peel-open sterile pouch, so you can grab one, open it, and start working—no extra steps required.

We also include a sterilization certificate with every order, so you can easily document compliance for audits or regulatory submissions (we know how important that paperwork is!).

4. Versatile Sizes for Every Sample

Whether you're storing small volumes of DNA or larger cell cultures, we have a size to fit. Our standard offerings include:

5. Easy Labeling and Traceability

We've all been there: a smudged label that makes a vial's contents unidentifiable. That's why our vials feature a large, matte writing surface that accepts permanent markers, even at low temperatures. For labs using barcoding systems, we offer vials with pre-printed 2D barcodes (compatible with most lab inventory software) or blank barcode-ready surfaces for your own labeling.

Each vial also has a unique batch number printed on the bottom, linked to our quality control records. If you ever have a question about a specific vial, just provide the batch number, and we can share its entire production history—from resin lot to sterilization date.
