Medical Plastic Packaging Factory Guangdong: Cryogenic Tubes Manufacturer

Cryogenic Tubes: The Backbone of Biostorage

As a cryogenic tubes manufacturer, we've spent years perfecting our design. Here's what makes our tubes stand out:

Unmatched Durability

We use medical-grade polypropylene (PP) because it's incredibly tough and can withstand temperatures as low as -196°C—yes, that's liquid nitrogen cold. PP is also resistant to chemicals, so it won't react with your samples. Unlike glass tubes, our plastic cryo tubes won't shatter if dropped, making them safer to handle.

Leak-Proof Seals

Our cryogenic tubes feature a silicone gasket that creates an airtight seal. We've tested these seals in every scenario: repeated freeze-thaw cycles, submersion in liquid nitrogen, even rough handling during transport. The result? Zero leaks. Your samples stay where they belong—inside the tube.

Sterility Guaranteed

All our cryo tubes are pre-sterilized using either ethylene oxide (EO) or gamma radiation. They're DNase/RNase-free and non-pyrogenic, so your samples remain pure and uncontaminated. No more wasting time sterilizing tubes yourself—they're ready to use right out of the box.

Versatile Sizes & Designs

We offer a range of sizes to fit your needs:

Real-World Results

Let's share a client success story. A leading pharmaceutical company was struggling with their previous cryo tube supplier—their tubes kept cracking during storage, leading to lost vaccine samples. They reached out to us, and we sent them a batch of our 2ml internal thread tubes. After three months of testing, they reported zero cracks and zero leaks. Now, they're one of our biggest clients. That's the kind of reliability we deliver.

Whether you're a small lab or a large biotech firm, our bulk cryogenic tubes are available at factory-direct prices. And if you need a custom size or design, our custom mold design team can create it for you.
