In the fast-paced world of pharmaceuticals, biotechnology, and medical research, the need for reliable sample storage solutions has never been more critical. Whether it's preserving life-saving vaccines, storing delicate cell cultures, or safeguarding genetic material for biobanking, the integrity of samples depends entirely on the quality of the containers that house them. This is where cryogenic tubes come into play—small but mighty tools designed to withstand extreme temperatures, ensuring samples remain viable even in the harshest conditions. As a leading cryogenic tubes manufacturer with decades of experience, we understand the stakes. Every vial, every seal, and every design choice is a promise to protect what matters most: the future of scientific discovery and patient health.
Cryogenic storage—maintaining materials at temperatures below -150°C, often using liquid nitrogen at -196°C—is the gold standard for long-term preservation of biological samples. From human stem cells to bacterial cultures, from viral vaccines to reproductive tissues, these samples are irreplaceable. A single compromised vial could set back years of research, delay clinical trials, or even risk patient safety. That's why choosing the right sterile cryo vials for liquid nitrogen isn't just a purchase decision—it's a commitment to scientific integrity.
Imagine a research lab working on a breakthrough cancer treatment. They've spent months isolating and culturing specialized cells, each one a potential key to unlocking new therapies. These cells need to be stored for future experiments, but without proper cryogenic protection, their structure could degrade, rendering all that hard work useless. Or consider a pharmaceutical company scaling up vaccine production: millions of doses rely on stable storage of viral strains, and any contamination or temperature fluctuation could ruin an entire batch. In these scenarios, the cryogenic tube isn't just packaging—it's a lifeline.
At our core, we're problem solvers. We don't just manufacture cryogenic tubes—we engineer solutions that address the unique challenges of low-temperature storage. Our team of material scientists, engineers, and quality control specialists work together to create products that meet the most stringent demands of the pharmaceutical and biotech industries. Here's how we stand out:
The first line of defense in cryogenic storage is the material of the tube itself. We exclusively use high-grade polypropylene (PP) for our cryogenic vials. Why PP? Unlike other plastics, PP remains flexible at ultra-low temperatures, resisting cracking even when exposed to rapid temperature changes—a common scenario when moving samples in and out of liquid nitrogen. This flexibility is crucial; a rigid material might shatter, exposing samples to contamination or loss. Our polypropylene cryogenic tubes (PP) are also autoclavable, allowing for pre-use sterilization, and chemically inert, ensuring they won't react with sensitive samples.
Even the best material is useless if the seal fails. That's why we've invested heavily in perfecting our closure systems. Our leak-proof cryotubes with silicone gasket are the result of years of testing and refinement. The silicone gasket, placed between the vial and cap, creates a hermetic seal that withstands both extreme cold and the pressure changes that occur during storage and transport. Unlike rubber gaskets, which can degrade over time or become brittle at low temperatures, our silicone gaskets maintain elasticity, ensuring a tight seal for years. We test every batch for leaks by submerging sealed vials in liquid nitrogen, then checking for signs of moisture ingress—a rigorous process that gives our clients peace of mind.
In pharmaceutical and clinical settings, sterility isn't optional—it's mandatory. Contamination with bacteria, fungi, or even DNase/RNase enzymes can render samples useless or, worse, produce false research results. That's why all our cryogenic vials come pre-sterilized via ethylene oxide (EO) or gamma radiation , two methods recognized by regulatory bodies worldwide for their ability to eliminate microorganisms without leaving harmful residues. EO sterilization is ideal for heat-sensitive components, while gamma radiation offers a higher level of penetration, ensuring even the innermost parts of the vial are sterile. Each batch is accompanied by a sterility certificate, so you can trust that your samples are starting in a contamination-free environment.
No two labs or applications are the same. That's why we offer a diverse range of cryogenic tubes, designed to meet the specific requirements of different samples, storage systems, and workflows. Whether you need small-volume vials for precious cell samples or larger containers for bulk storage, we have you covered. Here's an overview of our most popular options:

Each product is designed with user experience in mind. Our vials feature a frosted writable surface, allowing for easy labeling with permanent markers, and many are compatible with automated labeling systems for labs using barcoding. For biobanking applications, where sample traceability is critical, we offer barcoded or writable cryogenic vials that integrate seamlessly with laboratory information management systems (LIMS). We also provide custom printing options, including logos or batch numbers, for clients who need to brand their storage solutions or enhance traceability.
In the pharmaceutical industry, compliance isn't just a box to check—it's a way of life. We're proud to operate an ISO9001 certified packaging factory with a dust-free GMP compliant workshop, ensuring every step of our manufacturing process meets or exceeds international standards. Our quality control protocols start with raw material inspection: every batch of PP resin is tested for purity, flexibility, and chemical resistance before it's approved for production. During manufacturing, we monitor critical parameters like wall thickness (to ensure structural integrity) and gasket placement (to guarantee a consistent seal).
Post-production, each batch undergoes a battery of tests: leak testing in liquid nitrogen, sterility testing via incubation, and mechanical strength testing to ensure vials can withstand the rigors of daily lab use. We also test for DNase, RNase, and pyrogen contamination, critical for molecular biology and clinical applications. Our commitment to quality has earned us the trust of pharmaceutical giants, contract research organizations (CROs), and academic institutions worldwide.
Our cryogenic tubes are used in a wide range of applications, each with its own set of demands. Here are just a few areas where our products shine:
Biobanks store human biological samples (like blood, tissue, and DNA) for future research into diseases like cancer, Alzheimer's, and diabetes. These samples must remain viable for decades, making storage stability paramount. Our biobanking cryogenic tubes are designed for long-term liquid nitrogen storage, with features like non-pyrogenic materials and secure sealing to prevent cross-contamination. Many biobanks choose our barcoded vials for easy tracking, ensuring samples can be quickly located and traced back to their source.
The COVID-19 pandemic highlighted the critical role of reliable cold-chain storage. Many vaccines, including mRNA-based ones, require ultra-low temperature storage to maintain efficacy. Our cryogenic vials, with their robust seals and temperature resistance, are used by pharmaceutical companies to store vaccine strains during development and production. The pre-sterilized cryogenic vials (EO or gamma) ensure that vaccine materials remain uncontaminated, even during long-term storage.
Stem cell research, tissue engineering, and regenerative medicine rely on the ability to freeze and thaw cells without damaging their structure or function. Our polypropylene cryogenic tubes, with their flexibility at low temperatures, minimize cell damage during freezing and thawing cycles. The leak-proof seal also prevents the entry of liquid nitrogen, which can cause sample dilution or contamination when vials are removed from storage.
In clinical labs, cryogenic vials are used to store patient samples for future testing or retesting. For example, a blood sample might be stored to monitor disease progression or validate test results. Our sterile, DNase/RNase-free vials ensure that these samples remain unaltered, providing accurate results when needed.
