In the world of scientific research and biotech innovation, every sample matters. Whether you're preserving critical cell lines, storing vaccine components, or safeguarding rare biological materials, the containers you choose can make or break the integrity of your work. That's where we come in—as a leading cryogenic tubes manufacturer with decades of experience, we understand the pressure of keeping samples safe, even in the harshest conditions. Today, we're pulling back the curtain on our autoclavable cryo tubes: the reliable, high-quality solution that labs and pharmaceutical companies around the globe trust.
If you've been searching for a partner who doesn't just sell products, but delivers peace of mind, you're in the right place. Our cryo tubes aren't just plastic containers—they're the result of rigorous testing, medical-grade materials, and a commitment to excellence that's backed by ISO 9001 certification and a dust-free GMP compliant workshop. Let's dive into why so many researchers and businesses choose us for their cryogenic storage needs.
We get it—there are plenty of options out there when it comes to plastic containers. But when your work depends on precision and reliability, "good enough" simply won't cut it. Here's what makes our cryo tubes different:
-
Medical Grade, Through and Through:
Every cryo tube we produce is made from pharmaceutical-grade polypropylene (PP), a material chosen for its exceptional resistance to extreme cold (-196°C, the temperature of liquid nitrogen!) and its ability to withstand repeated autoclaving. No cheap plastics here—we're talking about materials that meet the strictest standards for medical and laboratory use.
-
Certified Quality You Can Trust:
As an ISO 9001 certified packaging factory, we don't just say we care about quality—we prove it. Our dust-free GMP compliant workshop ensures that every step of production, from raw material inspection to final packaging, happens in a controlled environment, minimizing contamination risks. For labs and biotech firms, this isn't just a nice-to-have; it's a necessity.
-
Engineered to Protect What Matters:
Leaks, cracks, or sample contamination are the stuff of nightmares for researchers. That's why our cryo tubes feature silicone gaskets that create an airtight seal, even under thermal shock. The conical or round bottom designs? They're not just for looks—they make centrifugation easier and sample retrieval more precise. Plus, our tubes come pre-sterilized (EO or gamma irradiated), so you can start using them right out of the box.
-
Custom Solutions for Your Unique Needs:
Every lab has different requirements. Maybe you need a specific volume, a unique cap design, or even custom labeling for traceability. Our custom mold design for plastic bottles (and tubes!) means we can turn your specifications into reality. From 3D to free mold testing, we're here to bring your vision to life.
Our Autoclavable Cryo Tubes Product Line: Designed for Every Application
No two research projects are the same, which is why we offer a range of cryo tubes to fit different needs. Whether you're storing small cell samples or larger volumes of biological fluids, we've got you covered. Here's a closer look at our most popular options:

But wait—what if you need something that's not on this list? Maybe a 1ml tube with a specific cap color, or a 10ml option for larger samples? That's where our custom mold design for plastic bottles shines. We've worked with labs to create one-of-a-kind cryo tubes that fit their exact protocols, and we'd love to do the same for you.
Need Something Custom? We've Got You Covered
At the end of the day, we know that off-the-shelf solutions don't always work. That's why we've invested in a full in-house mold design and manufacturing team. Here's how our custom process works:
-
Share Your Vision:
Send us your 3D, sample, or even just a sketch. Our design team will work with you to refine the details—volume, cap type, labeling options, and more.
-
Free Mold Testing:
Before full production, we'll create a prototype mold and produce test samples. This lets you verify fit, function, and performance without any upfront risk.
-
Scale Up with Confidence:
Once you're happy with the prototype, we'll move to mass production. Our state-of-the-art facilities can handle orders of any size, from small batches for pilot studies to large-scale production for biobanks.
Recent projects include a custom 3ml cryo tube with a built-in QR code for sample tracking and a specialized 0.2ml tube for ultra-small RNA samples. Whatever your needs, we're ready to collaborate.
Where Our Cryo Tubes Make a Difference: Real-World Applications
Our autoclavable cryo tubes aren't just for show—they're hard at work in labs, hospitals, and biotech companies around the world. Here are a few examples of how our customers use them:
-
Academic Research Labs:
Universities and research institutions rely on our tubes to store cell lines, plasmids, and experimental samples for long-term studies. The ability to autoclave and reuse tubes (when appropriate) helps labs reduce costs without compromising quality.
-
Pharmaceutical Companies:
When developing new drugs or vaccines, consistency is key. Our GMP-compliant tubes ensure that raw materials and intermediate products are stored safely, meeting regulatory requirements every step of the way.
-
Biobanks and Sample Repositories:
Biobanks storing human tissues, blood samples, or genetic material need containers they can trust for decades. Our cryo tubes' resistance to long-term liquid nitrogen storage makes them a top choice for these critical facilities.
-
Clinical Diagnostics:
Hospitals and diagnostic labs use our tubes to transport and store patient samples, from biopsies to blood work. The sterile, leak-proof design minimizes the risk of contamination during transit.
Behind the Scenes: Our Quality Control Process
We believe that quality isn't just a final check—it's a mindset that runs through every step of production. Here's a peek at how we ensure every cryo tube meets our high standards:
-
Raw Material Inspection:
Before any production starts, we test every batch of polypropylene for purity, density, and cold resistance. Only materials that pass our strict criteria make it into our workshop.
-
In-Process Monitoring:
Our production lines are equipped with real-time sensors that check for defects like thin walls, uneven threading, or gasket misalignment. If something's off, the line stops automatically—no faulty tubes make it past this stage.
-
Sterility Testing:
Random samples from each production run undergo sterility testing in our on-site lab. We use both EO and gamma irradiation methods, depending on customer needs, and provide certificates of sterility with every order.
-
Cold Shock Testing:
To simulate real-world use, we subject tubes to rapid temperature changes (from room temp to -196°C and back) and check for cracks or seal failure. Only tubes that survive 50+ cycles make the cut.
-
Final Packaging Check:
Before shipping, each tube is inspected for labeling accuracy, packaging integrity, and overall condition. We then pack them in moisture-proof, dust-free boxes to ensure they arrive in perfect condition.

Frequently Asked Questions (FAQs)
Q: Are your cryo tubes compatible with all liquid nitrogen storage systems?
A: Yes! Our tubes are designed to work with standard liquid nitrogen tanks, cryo boxes, and storage racks. The external dimensions are standardized to fit most lab equipment. If you have a specialized system, just share the specs, and we can confirm compatibility (or even design a custom tube that fits!).
Q: How many times can I autoclave your cryo tubes?
A: Our tubes are rated for up to 20 autoclave cycles (121°C, 15 psi, 30 minutes). After that, we recommend replacing them to ensure the seal remains intact. Many customers reuse them for non-critical samples (like controls) after this, but we always advise following your lab's protocols.
Q: Do you offer private label or custom branding options?
A: Absolutely! We can add your logo, lab name, or even custom barcodes/QR codes to the tubes or packaging. For large orders, we also offer custom box designs with your branding—great for companies that want a cohesive look across their supplies.
Q: What's the minimum order quantity (MOQ) for custom cryo tubes?
A: For standard sizes, there's no MOQ—we can fulfill orders as small as 100 tubes. For custom mold designs, the MOQ is typically 10,000 tubes, but we're happy to discuss lower quantities for prototype runs or pilot studies.
Q: Are your cryo tubes DNase/RNase-free?
A: Yes! All our tubes undergo a specialized cleaning process to remove DNase, RNase, and pyrogens, making them safe for molecular biology applications like PCR, RNA sequencing, and gene editing studies.
