Lab & Pharma -196°C Cryogenic Tubes | ISO Certified Quality

Storing life-saving vaccines, delicate cell samples, or critical DNA research at -196°C—temperatures so cold that air turns liquid—demands containers you can trust with your most valuable work. A single leak or contamination event can ruin months of research, delay clinical trials, or compromise patient safety. That's where our -196°C cryogenic tubes come in. As a leading cryogenic tubes manufacturer, we understand the stakes of lab and pharmaceutical storage, and we've engineered our tubes to deliver uncompromising reliability when it matters most.

But our commitment doesn't stop at cryo tubes. We're a full-service provider of medical grade plastic bottles and packaging solutions, designed to meet the rigorous standards of lab and pharma industries. From HDPE pill bottles to custom mold design, every product we make is backed by our ISO 9001 certification and GMP compliance—ensuring consistency, safety, and quality in every batch.

What Makes Our -196°C Cryogenic Tubes Stand Out?

Let's dive into the details that set our cryogenic tubes apart from generic alternatives. Every feature is designed with the unique challenges of ultra-low temperature storage in mind:

1. Medical-Grade Material

We use only premium medical-grade polypropylene (PP) for our cryogenic tubes. PP is the gold standard for ultra-low temperature storage because it retains its structural integrity at -196°C—no cracking, warping, or brittleness. Unlike cheaper plastics that may break under extreme cold, our PP tubes are tested to withstand repeated cycles of freezing and thawing without losing their shape or seal.

Our PP resin is sourced from reputable suppliers and undergoes rigorous testing for purity. We check for heavy metals, contaminants, and chemical leaching to ensure it meets the strictest medical grade standards. This means your samples stay safe and uncompromised, even during long-term storage.

2. Leak-Proof Silicone Seal

The seal is the most critical part of any cryogenic tube. A faulty seal can lead to sample loss, contamination, or even explosion (if liquid nitrogen seeps into the tube and expands during thawing). Our tubes feature a high-quality silicone gasket that creates an airtight, leak-proof seal—even at -196°C.

We put our seals through extreme tests: submerging tubes in liquid nitrogen for 24 hours, shaking them vigorously, and dropping them from a height of 1 meter. In every case, our seals held firm, with zero leaks. For labs and pharma companies storing irreplaceable samples, this level of reliability is non-negotiable.

3. Sterility You Can Trust

Contamination is a nightmare for any lab or pharma project. Our cryogenic tubes are available in two sterilization options: ethylene oxide (EO) and gamma radiation. Both methods ensure the tubes are DNase/RNase-free, non-pyrogenic, and free of bacteria and fungi.

We also use a dust-free gmp compliant workshop for all sterile product production. This means our tubes are manufactured in an environment with controlled air quality—no dust, no particles, no contaminants. Every batch is tested for sterility before it leaves our factory, so you can be confident your samples are safe.

4. Versatile Sizes & Features

We offer a range of cryogenic tube sizes to fit different storage needs, from small 0.5ml tubes for DNA samples to 5ml tubes for larger cell batches. Our tubes come with either internal or external threads—internal threads are ideal for preventing cross-contamination, while external threads are easier to open with gloves on. You can also choose between conical and round bottoms: conical bottoms are perfect for centrifugation, while round bottoms work well for general storage.

Other key features include:

• A writable surface that resists smudging, even with permanent markers.
• Optional barcode printing for easy inventory management.
• Clear labeling with batch number and expiration date.
• Compatibility with standard cryo storage racks.

Beyond Cryo Tubes: Our Medical Grade Plastic Packaging Solutions

As a full-service medical grade plastic bottles supplier, we offer a range of products to meet the diverse needs of lab and pharmaceutical industries. Here are some of our most popular solutions:
