Wholesale Pre-Sterilized Cryogenic Vials (EO or Gamma) – Custom Logo & Packaging Options

In the world of scientific research, biobanking, and pharmaceutical development, the difference between success and failure often lies in the details—especially when it comes to preserving valuable samples. Whether you're storing rare cell lines, vaccine candidates, or sensitive biological materials, the containers you choose can make or break years of hard work. That's where pre-sterilized cryogenic vials come into play: the unsung heroes of low-temperature storage, designed to protect what matters most, even at the extreme cold of liquid nitrogen.

As a leading cryogenic tubes manufacturer , we understand the stakes. A single compromised vial can lead to sample contamination, loss of data, or even setbacks in life-saving research. That's why we've dedicated decades to perfecting our cryogenic vials—combining rigorous quality standards, innovative design, and customizable options to meet the unique needs of labs, clinics, and biotech companies worldwide.

When you're working with sensitive biological materials, sterility isn't just a preference—it's a requirement. Traditional vials that require in-house sterilization not only add extra steps to your workflow but also introduce room for error. Did the autoclave reach the right temperature? Was the cooling process properly monitored? These questions vanish with pre-sterilized options.

Our pre-sterilized cryogenic vials (EO or gamma) undergo rigorous sterilization processes before leaving our facility, ensuring they arrive ready to use. This not only saves your team valuable time but also eliminates the risk of cross-contamination from improper in-lab sterilization. For busy labs handling hundreds of samples daily, this efficiency can transform operations—letting researchers focus on what they do best: science.

Not all cryogenic vials are created equal. Ours are engineered with precision, focusing on the details that matter most in extreme cold conditions:

Leak-Proof Design: The last thing you want is a vial that leaks when submerged in liquid nitrogen. Our leak-proof cryotubes with silicone gasket ensure a tight seal, even at -196°C. The silicone gasket conforms to the vial's neck, creating a barrier against liquid nitrogen ingress and sample loss. We test every batch for leaks using pressure and temperature cycling to guarantee reliability.

Durable Polypropylene Construction: Made from high-quality polypropylene (PP), our vials are shatter-resistant and withstand extreme temperature fluctuations. Unlike glass, PP won't crack when moving from liquid nitrogen to room temperature, making them ideal for repeated freeze-thaw cycles.

DNase/RNase-Free and Non-Pyrogenic: For molecular biology applications, purity is critical. Our vials are manufactured in a dust-free, controlled environment and tested to ensure they're free of DNase, RNase, and pyrogens—protecting your samples from degradation and ensuring accurate test results.

Clear Marking Options: Keeping track of samples is easier with our barcoded or writable cryogenic vials . Choose from pre-printed barcodes for easy tracking in LIMS systems or writable surfaces that work with permanent markers, even after freezing. No more smudged labels or lost samples.

Sterilization is the backbone of reliable cryogenic storage, and we offer two industry-leading methods to meet your needs: ethylene oxide (EO) and gamma irradiation. Each has its advantages, and the right choice depends on your application:

Ethylene Oxide (EO) Sterilization: EO is a gas sterilization method ideal for heat-sensitive materials. It penetrates packaging and vials thoroughly, killing microorganisms without damaging the vial or its contents. Our EO-sterilized vials undergo aeration to remove residual gas, ensuring they're safe for immediate use. This method is particularly popular for vials used in cell culture and IVF applications.

Gamma Irradiation: Gamma sterilization uses high-energy photons to destroy microorganisms, offering a faster turnaround time than EO. It's highly effective for large batches and works well for vials intended for long-term storage. Gamma-sterilized vials are often preferred in pharmaceutical and vaccine storage, where rapid availability is key.

Both methods are validated to meet ISO 11135 (EO) and ISO 11137 (gamma) standards, with sterility assurance levels (SAL) of 10⁻⁶—meaning there's less than a one-in-a-million chance of a non-sterile unit.

Every sample has unique storage needs, which is why we offer a range of vial sizes and configurations. Whether you're storing small volumes of precious cell lines or larger quantities of vaccine formulations, we have a solution:


Conical vs. Round Bottom: Conical bottom vials are ideal for pelleting cells, as they concentrate samples at the bottom for easy retrieval. Round bottom vials, on the other hand, are better for storing liquids and allow for more uniform freezing. Both designs work seamlessly with standard cryo racks and storage boxes.

Thread Options: Internal thread vials offer a lower profile, saving space in storage boxes, while external thread vials provide easier handling with gloves—perfect for busy labs where dexterity is limited.

We understand that your brand and workflow are unique, which is why we offer a range of customization options to make our vials feel like an extension of your lab:

Custom Logos and Branding: Add your lab's logo, name, or contact information to vials or packaging. This not only enhances brand recognition but also helps prevent mix-ups in shared lab spaces.

Barcoding and Labeling: Beyond our standard barcoded or writable cryogenic vials , we can create custom barcode sequences tailored to your LIMS system. This ensures seamless integration with your existing tracking software, reducing the risk of human error.

Packaging Solutions: Choose from bulk packaging (bags of 50 or 100 vials) for high-throughput labs or individual blister packs for added sterility assurance. We also offer custom box designs with your branding, making them perfect for distribution to satellite labs or.

Private Label Options: For companies looking to offer cryogenic vials under their own brand, we provide full private label services—from design to delivery. This includes custom color options for caps or vials, matching your brand's aesthetic.

Our cryogenic vials serve a wide range of industries, each with unique needs:

Biobanking: Storing human, animal, or plant samples for future research. Our vials' durability and sterility make them ideal for long-term storage in biorepositories.

Pharmaceutical Development: Protecting vaccine candidates, drug formulations, and API samples during stability testing and transport.

Clinical Research: Storing patient samples for diagnostic testing or personalized medicine studies. The clear marking options ensure accurate sample tracking.

IVF Clinics: Preserving sperm, eggs, and embryos with the highest level of sterility and safety.

Academic Labs: Supporting research in genetics, cell biology, and neuroscience with reliable, cost-effective storage solutions.

Quality is the foundation of everything we do. Our manufacturing facility is ISO 9001 certified and features dust-free, GMP-compliant workshops—ensuring every vial meets the highest standards. Here's how we ensure quality:

Incoming Material Testing: We source only medical-grade PP and silicone gaskets, testing each batch for purity and durability.

In-Process Inspections: Every production step is monitored, from molding to assembly, to ensure consistent dimensions and seal integrity.

Final Testing: Random samples from each batch undergo leak testing (submersion in colored water under pressure), sterility testing, and temperature cycling to simulate real-world use.

Documentation: We provide full batch records, including sterilization validation reports, to help you maintain compliance with regulatory bodies like the FDA and EMA.
