When you're storing samples at -196°C (that's the temperature of liquid nitrogen!), there's no room for error. Our vials are designed with the smallest details in mind, because we know those details are what keep your samples safe. Let's break down the features that make a real difference in the lab:
Medical-Grade Materials You Can Trust
We start with the basics: material. All our cryogenic vials are made from high-purity polypropylene (PP), a plastic known for its exceptional cold resistance and chemical stability. Unlike cheaper plastics that can become brittle at low temperatures or leach harmful substances into your samples, our
medical grade plastic bottles
meet the strictest standards for biocompatibility. That means no unwanted interactions, no sample contamination, and peace of mind knowing your materials are as pure as the day you collected them.
Leak-Proof Design: Because Even a drop Matters
There's nothing more frustrating than pulling a vial out of storage only to find it's leaked. We've tested dozens of closure designs to find the one that works every time. Our vials come with silicone gaskets that create an airtight seal, even after repeated freeze-thaw cycles. The screw-top lids are designed to be easy to twist—even with gloves on—but tight enough to prevent any liquid nitrogen from seeping in. We've had researchers tell us they've dropped our vials (by accident, of course!) and still found the samples intact. That's the kind of reliability we stand behind.
Temperature Tolerance: Built for the Extremes
Liquid nitrogen storage isn't just cold—it's
extremely
cold. Our vials are rigorously tested to ensure they can handle temperatures as low as -196°C without cracking, warping, or losing their seal. Whether you're using them in a standard cryogenic tank or a ultra-low temperature freezer, you can trust that these vials will keep up with your lab's demands. We even test them under thermal shock conditions (rapidly moving from room temperature to -196°C) to make sure they hold up in real-world scenarios.
