EO/Gamma Sterilized Pre-Sterilized Cryogenic Vials – Custom Sizes & Labels Available

Why Sterility Matters in Cryogenic Storage

For researchers, lab technicians, and biobank managers, the stakes couldn't be higher when it comes to storing biological samples. Whether you're preserving DNA, cell cultures, vaccines, or patient specimens, a single contamination or leakage can compromise months—even years—of hard work. That's why choosing the right cryogenic vials isn't just about picking a container; it's about investing in peace of mind.

At our core, we know that sterility isn't optional in cryogenic storage—it's essential. That's why we've made it our mission to craft pre-sterilized cryogenic vials that you can trust, day in and day out. As a dedicated cryogenic tubes manufacturer with years of experience, we understand the unique challenges of your work, and we've built our products to rise to every one of them.

Our EO/Gamma Sterilized Cryogenic Vials: Built for Reliability

When you choose our pre-sterilized cryogenic vials, you're choosing a product designed to stand up to the harshest conditions—from ultra-low temperatures to rigorous handling. Let's break down what makes them different:

Medical Grade Plastic: The Foundation of Durability

Every vial starts with high-quality polypropylene (PP), a medical grade plastic known for its exceptional cold resistance and chemical stability. Unlike lower-grade plastics that can crack or leach harmful substances at -196°C (the temperature of liquid nitrogen), our PP vials maintain their integrity, ensuring your samples stay safe, even during long-term storage.

Dual Sterilization Options: EO or Gamma—Your Choice

We know that different labs have different needs, which is why we offer two industry-leading sterilization methods:

• EO Sterilization: Ethylene Oxide gas sterilization is ideal for vials that need to remain free of residual radiation. It penetrates every corner of the vial, eliminating 99.9% of bacteria, viruses, and fungi without damaging the plastic.
• Gamma Sterilization: For labs requiring the highest level of sterility assurance, gamma irradiation delivers powerful, consistent sterilization. It's fast, reliable, and leaves no chemical residues—perfect for critical applications like cell therapy or vaccine development.

Whichever method you choose, rest assured: every batch of vials undergoes rigorous sterility testing before leaving our facility. We don't just meet industry standards—we exceed them.

Leak-Proof Design: Because Even a ｄｒｏｐ Matters

There's no room for error when it comes to sample containment. Our vials feature a silicone gasket sealed cap that creates an airtight barrier, preventing leaks, contamination, and sample evaporation. Whether you're centrifuging, transporting, or storing samples in liquid nitrogen vapor or immersion, our vials stay sealed tight.

Custom Solutions Tailored to Your Needs

We get it: no two labs are exactly alike. What works for a small research team might not fit the needs of a large biobank or pharmaceutical company. That's why we don't just offer "one-size-fits-all" vials—we offer custom solutions designed around your workflow.

Custom Mold Design for Plastic Bottles (and Vials!)

Need a vial size that's not on our standard list? Or a unique shape to fit your automated storage system? Our in-house mold design team can turn your idea into reality. We specialize in custom mold design for plastic bottles and containers, and we apply that expertise to cryogenic vials too. From 3D to free mold testing, we'll work with you every step of the way to ensure the final product meets your exact specifications.

Labels That Keep Up with Your Samples

Tracking samples shouldn't be a headache. We offer custom labeling options to make sample management easier than ever:

• Barcode/QR Code Printing: Integrate with your lab's LIMS system for seamless tracking.
• Custom Logos & Text: Add your lab name, project number, or logo for brand consistency.
• Color-Coded Caps: Organize samples by type, date, or researcher with colored caps (available in blue, green, red, and more).

We know that time is precious in the lab, so we keep the customization process simple. Share your requirements, and we'll handle the rest—no complicated paperwork, no long wait times.

Beyond the Vial: Our Quality Commitment

We believe that great products start with great processes. As an ISO9001 certified packaging factory, we've built our reputation on strict quality control—from raw material selection to the final product.

Dust-Free GMP Compliant Workshop: Where Cleanliness is Non-Negotiable

Our production facility isn't just a factory—it's a controlled environment designed to prevent contamination at every stage. Our dust-free GMP compliant workshop features HEPA filtration systems, positive air pressure, and regular air quality testing. Every employee follows strict gowning procedures, and equipment is sanitized daily. When you open a box of our vials, you're opening a product made in a space that meets the same standards as pharmaceutical manufacturing facilities.

End-to-End Quality Checks

We don't leave quality to chance. Here's what sets our process apart:

• Raw Material Testing: Every batch of PP resin is tested for purity, melt flow rate, and cold resistance before production.
• In-Process Inspection: Our team checks vial dimensions, cap fit, and seal integrity during manufacturing.
• Sterility Validation: Post-sterilization, samples from each batch undergo bacterial endotoxin testing and sterility assurance level (SAL) verification.
• Packaging Checks: Vials are packed in tamper-evident, moisture-resistant packaging to ensure sterility is maintained until use.

We're so confident in our quality that we provide a certificate of analysis (COA) with every order. It's our way of showing you exactly what went into making your vials—and why you can trust them with your most valuable samples.

Partnering with a Trusted Cryogenic Tubes Manufacturer

Choosing a cryogenic vial supplier is about more than buying a product—it's about building a partnership. Here's why labs, biobanks, and pharmaceutical companies around the world choose to work with us:

• Experience You Can Rely On: With years in the industry, we've seen it all. We understand the unique challenges of cryogenic storage, and we use that knowledge to solve your problems.
• Flexibility to Adapt: Whether you need a small batch of custom vials or bulk orders for a large-scale project, we scale to meet your needs. No minimum order quantities (MOQs) for standard sizes—because we believe every lab deserves access to quality.
• Transparent Communication: We keep you in the loop from design to delivery. Have a question? Our team responds quickly, with clear, jargon-free answers.
• Sustainability in Mind: We're committed to reducing our environmental impact. Our vials are made from recyclable PP, and we're constantly exploring sustainable plastic packaging solutions to minimize waste.
