When you're responsible for preserving life-saving vaccines, rare biological samples, or critical research data, the last thing you need is to worry about the reliability of your storage containers. For over a decade, we've stood beside scientists, pharmaceutical developers, and laboratory managers as a partner who understands the stakes of their work. As an ISO 9001 certified cryogenic tubes manufacturer, we don't just sell plastic containers—we deliver peace of mind, one carefully crafted tube at a time.

In the world of biomedical research, where a single compromised sample can set back years of work, choosing the right partner isn't just a business decision; it's a commitment to excellence. Our journey began in Guangdong, China, with a simple mission: to create plastic packaging solutions that meet the most rigorous standards, so our clients can focus on what they do best—innovating, discovering, and healing.

Founded in the early 2010s, we started as a small team with big dreams: to redefine what a plastic packaging supplier could be. While many factories focused solely on volume, we set out to balance efficiency with an unwavering focus on quality. Today, that vision has grown into a 20,000-square-meter facility equipped with state-of-the-art manufacturing lines, a dedicated R&D center, and a dust-free GMP compliant workshop that's the backbone of our medical-grade production.

Our journey to ISO 9001:2015 certification wasn't just about hanging a plaque on the wall—it was about embedding quality into every step of our process. From raw material selection to final inspection, every team member is trained to ask: "Would I trust this product with my own research?" That commitment has made us a preferred partner for clients in over 40 countries, from small biotech startups to Fortune 500 pharmaceutical companies.

But certifications alone don't tell the whole story. What truly sets us apart is our people. Our engineers have an average of 15 years of experience in plastic mold design, and our quality control team includes specialists with backgrounds in biomedical engineering. When you work with us, you're not just getting a supplier—you're gaining access to a network of experts who care about your success as much as you do.

Cryogenic storage isn't for the faint of heart. Samples frozen at -196°C demand containers that can withstand extreme temperature fluctuations, resist cracking, and maintain an airtight seal to prevent contamination. Our cryogenic tubes are built to rise to this challenge, with features designed by scientists, for scientists.

Material Matters: The Science of Polypropylene

We exclusively use medical-grade polypropylene (PP) for our cryogenic tubes, and for good reason. PP is renowned for its exceptional cold resistance, chemical inertness, and durability—properties that make it ideal for long-term storage in liquid nitrogen environments. Unlike cheaper plastics that become brittle at low temperatures, our PP tubes maintain their integrity even after repeated freeze-thaw cycles, ensuring your samples stay protected, no matter how long they're stored.

A Range of Sizes for Every Need

Every research project is unique, which is why we offer a full spectrum of cryogenic tube sizes to match your specific requirements. Whether you're storing tiny cell cultures or larger tissue samples, we have a solution designed to fit:

Features That Protect What Matters Most

Our cryogenic tubes aren't just about size—they're packed with thoughtful details that make a difference in real-world use:

• Leak-Proof Assurance: Each tube features a silicone gasket (or O-ring) that creates an airtight seal, preventing liquid nitrogen ingress and sample cross-contamination. We test every batch for leaks using a vacuum chamber method, ensuring zero defects before shipment.
• Sterility You Can Count On: All our cryogenic tubes undergo ethylene oxide (EO) sterilization, a process that eliminates 99.9% of microorganisms without leaving harmful residues. Each tube is individually wrapped in peel-open packaging for easy, aseptic handling in your lab.
• Easy Identification: Every tube comes with a writable surface and clear graduation marks, making sample labeling simple and error-free. For high-throughput labs, we also offer barcoded options that integrate seamlessly with most lab inventory systems.
• Temperature Tolerance: Our tubes are rated for use from -196°C (liquid nitrogen) up to 121°C (autoclaving), giving you the flexibility to sterilize and reuse them when needed—a sustainable choice that reduces waste and cost.

While our standard cryogenic tubes work for most applications, we understand that some projects demand something extra. Maybe you need a specialized cap design to fit your automated pipetting system, or a unique tube shape to optimize storage space in your cryogenic tank. Whatever your challenge, our custom mold design service is here to turn your vision into reality.

From Idea to Prototype: The Custom Mold Process

Our custom mold design process is built to be collaborative and stress-free. Here's how it works:

1. Share Your Vision: Start by sending us your requirements—whether it's a 3D drawing, a sketch, or just a list of needs. Our engineering team will review your request and schedule a consultation to discuss details like material selection, volume, and timeline.
2. Design & Simulation: Using advanced CAD software, we'll create a detailed 3D model of your custom tube, complete with simulations to test its performance under cryogenic conditions. We'll share this model with you for feedback, making adjustments until it's perfect.
3. Free Prototype Testing: Once the design is finalized, we'll produce a small batch of prototype tubes for you to test in your lab. This step is crucial—it lets you verify that the tube works with your samples and equipment before committing to full production.
4. Full-Scale Production: After you approve the prototype, we'll manufacture the custom mold and begin production. We keep you updated every step of the way, so you're never in the dark about progress.

One recent client, a leading biotech firm developing a breakthrough cancer treatment, came to us with a problem: their current cryogenic tubes were too wide to fit in their automated storage system. Our team designed a slimmer 2ml tube with a unique interlocking base that allowed them to double their storage capacity without replacing their existing equipment. Today, they're one of our longest-standing partners—and we're proud to have played a small role in their life-changing work.

Walk through our dust-free GMP compliant workshop, and you'll see quality isn't just a buzzword—it's a way of life. From the moment raw materials arrive to the second finished tubes are packaged, every step is controlled, monitored, and documented to ensure compliance with the strictest global standards.

The GMP Difference: A Commitment to Cleanliness

Our Class 8 dust-free workshop is designed to minimize contamination risks, with HEPA filtration systems, positive air pressure, and strict gowning protocols for all staff. We regularly test air quality, surface cleanliness, and particle counts to ensure our environment meets or exceeds GMP guidelines—because even a single speck of dust can compromise a sensitive sample.

Quality Control: Testing That Leaves No Room for Error

Before any batch of cryogenic tubes leaves our facility, it undergoes a battery of tests designed to simulate the toughest real-world conditions:

• Leak Testing: Each tube is submerged in water and pressurized to 30kPa to check for micro-leaks—a test that ensures even the smallest defect is caught.
• Cold Shock Testing: Tubes are exposed to -196°C liquid nitrogen for 24 hours, then rapidly warmed to room temperature to verify they maintain their integrity.
• Chemical Resistance: We test tubes with common laboratory reagents to ensure they don't leach harmful substances or degrade over time.
• Torque Testing: Caps are tightened to specified torque levels to ensure consistent sealing and prevent accidental opening during storage.

We also maintain a comprehensive batch record system that tracks every tube from production to shipment. If you ever need to trace a specific batch, we can provide detailed documentation, including raw material certificates, test results, and sterilization records—giving you full transparency and confidence in your purchase.
