Low-Temperature Resistant Cell Freezing Cryogenic Tubes for Labs
Publish Time : 2025-12-25
For researchers working with biological samples, the choice of cryogenic storage equipment is more than just a purchase—it's a commitment to preserving the integrity of years of hard work. Whether you're storing stem cells, viral vectors, or patient-derived samples, the container that holds these materials must stand up to extreme conditions, maintain sterility, and prevent contamination. This is where the right cryogenic tube becomes not just a tool, but a critical partner in scientific progress. As a dedicated cryogenic tubes manufacturer with years of experience serving the global scientific community, we understand the stakes. Every sample matters, and every tube we produce is built to protect what matters most.
Engineered for the Toughest Conditions: What Sets Our Cryogenic Tubes Apart
Not all plastic tubes are created equal—especially when it comes to withstanding the harsh environment of liquid nitrogen storage at -196°C. Our cryogenic tubes are designed with three core principles in mind: reliability, purity, and user-centric functionality. Let's break down the features that make them indispensable for labs worldwide.
Medical Grade Plastic: The Foundation of Trust
At the heart of every tube is high-quality polypropylene (PP), a material chosen for its exceptional cold resistance and biocompatibility. Unlike standard plastics that become brittle at low temperatures, our medical grade plastic bottles are formulated to maintain structural integrity even after repeated cycles of freezing and thawing. This means no cracks, no leaks, and no loss of precious samples. What's more, our PP is non-toxic, tasteless, and free from harmful additives like BPA, ensuring that your samples remain uncontaminated from the moment they're placed inside.
Leak-Proof Sealing: Because Even a ｄｒｏｐ Matters
A tube is only as good as its seal. That's why we've invested in precision-engineered closures that eliminate the risk of leakage, even under extreme pressure. Each tube features a silicone gasket integrated into the screw cap, creating a tight, uniform seal that prevents liquid nitrogen ingress and sample evaporation. The threading on both the tube and cap is machined to exact tolerances, ensuring a secure fit every time—no cross-threading, no loose caps, just peace of mind for researchers who can't afford mistakes.
Design Details That Simplify Lab Work
We know lab work is busy enough without struggling with cumbersome equipment. Our cryogenic tubes include small but impactful design touches: a frosted writing area for easy sample labeling (no smudging, even with cryo markers), a conical bottom for efficient centrifugation, and a uniform wall thickness that ensures consistent heat transfer during freezing. Available in multiple volumes—from 0.5ml microtubes for small samples to 5ml tubes for larger cultures—they're versatile enough to handle diverse research needs.
Cryogenic Tubes Specifications: Find the Right Fit for Your Lab
| Model | Capacity | Material | Working Temperature | Cap Type | Bottom Design | Sterility |
|---|---|---|---|---|---|---|
| CT-05 | 0.5ml | Medical Grade PP | -196°C to +121°C | Screw Cap with Silicone Gasket | Conical | Gamma Sterilized (DNase/RNase-Free) |
| CT-18 | 1.8ml | Medical Grade PP | -196°C to +121°C | Screw Cap with Silicone Gasket | Conical | Gamma Sterilized (DNase/RNase-Free) |
| CT-20 | 2ml | Medical Grade PP | -196°C to +121°C | Screw Cap with Silicone Gasket | Round | Gamma Sterilized (DNase/RNase-Free) |
| CT-50 | 5ml | Medical Grade PP | -196°C to +100°C | Screw Cap with Silicone Gasket | Round | Gamma Sterilized (DNase/RNase-Free) |
All models are compatible with standard cryo racks and boxes, and can be autoclaved at 121°C for 20 minutes (except 5ml model, max 100°C).
Built to the Highest Standards: ISO 9001 & GMP Compliance
Quality isn't optional when it comes to lab supplies—it's mandatory. That's why our entire production process is rooted in rigorous standards that have earned us recognition as an iso9001 certified packaging factory and a leader in GMP-compliant manufacturing.
Dust-Free GMP Compliant Workshop: Where Cleanliness Meets Precision
Our production facility features a Class 8 dust-free workshop, designed to minimize particulate contamination during manufacturing. Every step—from raw material inspection to final packaging—is carried out in controlled environments with HEPA filtration and regular air quality monitoring. Employees wear full cleanroom attire, and equipment is sanitized daily to ensure that every tube meets the sterility requirements of pharmaceutical and biotech labs. For researchers working with sensitive samples, this level of cleanliness isn't just a bonus; it's a necessity.
End-to-End Quality Control
We don't just test finished products—we test every stage of production. Raw materials undergo batch testing for purity and mechanical properties. In-process checks ensure that mold dimensions are within microns of specifications. Finished tubes are subjected to leak tests (submerged in colored water under pressure), temperature cycling tests (from -196°C to room temperature, repeated 50 times), and sterility checks using validated methods. Only tubes that pass 100% of these tests make it to our customers. It's a strict process, but we believe scientific research deserves nothing less.
Beyond Standard: Custom Mold Design for Your Unique Needs
While our standard tubes work for most applications, we understand that some labs have specialized requirements. Maybe you need a unique volume, a custom label area, or a tube designed to fit a specific centrifuge rotor. That's where our custom mold design for plastic bottles comes in. Our in-house design team works directly with you to turn your ideas into reality—no middlemen, no delays.
How It Works: From Idea to Sample in Weeks
1. Collaboration: Share your requirements—whether it's a sketch, 3D model, or just a list of needs. Our engineers will provide feedback on feasibility, material selection, and cost optimization. 2. Design & Prototyping: Using advanced CAD software, we'll create a detailed 3D design and produce a prototype mold. We offer free mold testing to ensure the prototype meets your expectations before full production. 3. Production: Once approved, we'll manufacture the final mold and begin production. Even for custom orders, we maintain the same strict quality control as our standard products. 4. Support: Need to tweak the design later? We keep mold files on hand for easy modifications, making it simple to adapt as your research evolves.
Recent custom projects include a 0.2ml ultra-micro tube for single-cell sequencing labs and a 10ml tube with a integrated barcode area for automated sample tracking systems. Whatever your need, we're here to build it.
Where Science Meets Storage: Real-World Applications
Our cryogenic tubes serve a wide range of scientific fields, each with its own unique demands. Here are just a few examples of how labs around the world use our products:

Answers to Your Most Pressing Questions
Are your cryogenic tubes compatible with automated filling systems?
Yes! Our standard tubes have uniform dimensions and a straight neck design that works with most automated liquid handling equipment. For custom systems, we can adjust tube geometry to ensure compatibility—just share your system specs, and our engineers will help design a solution.
Can the tubes be reused after autoclaving?
While our tubes are designed for single-use in most clinical settings, they can be autoclaved at 121°C for 20 minutes if needed for non-critical applications. However, repeated autoclaving may reduce the integrity of the seal over time, so we recommend using fresh tubes for sensitive samples.
Do you offer documentation for regulatory submissions (e.g., FDA, EMA)?
Absolutely. We provide comprehensive documentation packages, including material safety data sheets (MSDS), certificate of analysis (COA) for each batch, and GMP compliance records. Our team can also assist with preparing documentation specific to regulatory submissions—just let us know your requirements.
What's the shelf life of your cryogenic tubes?
When stored in original, unopened packaging at room temperature, our tubes have a shelf life of 3 years. After opening, we recommend using them within 6 months to ensure sterility.
