Medical-Grade Non-Pyrogenic Sterile Cryotubes | Custom Labeling Available

What Makes a High-Quality Cryotube?

Not all cryotubes are created equal. To be truly effective, a cryotube must have several key features:

Medical Grade & Non-Pyrogenic

Medical-grade materials are essential for any cryotube used in healthcare or research. Our cryotubes are made from medical-grade polypropylene (PP) that's free from harmful chemicals and additives. Non-pyrogenic means there are no endotoxins present—substances that could cause fever or adverse reactions if they come into contact with biological samples. This is especially important for samples that will be used in humans, like vaccine candidates or patient specimens.

Sterile

Sterility is non-negotiable. Our sterile cryo vials for liquid nitrogen undergo rigorous sterilization processes, either using ethylene oxide (EO) or gamma radiation. This ensures that no bacteria, fungi, or other contaminants are present, which could compromise your samples. Each batch is tested for sterility before it leaves our factory, so you can be confident that every tube is safe to use.

-196°C Cryogenic Storage Tubes

Liquid nitrogen storage requires tubes that can withstand temperatures as low as -196°C. Our cryotubes are designed to handle these extreme conditions without cracking or becoming brittle. The material we use has a high glass transition temperature, meaning it remains flexible even at ultra-low temps. This prevents the tube from breaking when you take it out of the freezer, which is a common problem with lower-quality tubes.

Leak-Proof Cryotubes with Silicone Gasket

A leaky cryotube is a disaster waiting to happen. If liquid nitrogen seeps into the tube, it can expand when thawed and cause the tube to burst, ruining your sample. Our cryotubes feature a silicone gasket that creates an airtight seal, even at -196°C. We test every tube for leaks using a pressure test—submerging it in liquid and applying pressure to ensure no air or liquid can get in or out. This gives you peace of mind knowing your samples are safe.

DNase/RNase-Free

For molecular biology research, DNase and RNase enzymes can degrade DNA and RNA samples. Our cryotubes are treated to be DNase/RNase-free, so your genetic samples remain intact. This is crucial for experiments like PCR, sequencing, or gene expression analysis.

Our Range of Cryotubes: Features & Specifications

We offer a wide variety of cryotubes to meet the needs of different applications. Whether you need a small tube for cell samples or a large one for vaccine batches, we have you covered. Here's a detailed look at our most popular models:

Each model is designed with specific use cases in mind. For example, the CT-05 is perfect for storing small cell samples or DNA/RNA, while the CT-100 is ideal for large-scale vaccine storage. The conical bottom shape makes it easy to pellet cells, while the round bottom is better for liquid samples. All our tubes are compatible with standard cryo storage racks and freezers, so you don't have to worry about compatibility issues.

We also offer optional features like barcoding and writable surfaces. Barcoding makes it easy to track samples using a lab information management system (LIMS), while writable surfaces allow you to label samples by hand for quick identification. Our tamper-evident caps ensure that your samples haven't been opened or tampered with, which is important for regulatory compliance in clinical trials.

Customization Options: Tailored to Your Needs

Every lab has unique needs, and we believe your cryotubes should reflect that. That's why we offer a range of customization options to help you create the perfect tube for your application.

Private Label Plastic Packaging

Branding isn't just for consumer products—it's also important for labs and medical facilities. Our private label plastic packaging option allows you to add your company logo, lab name, or even specific sample information to the cryotubes. This makes it easier to organize samples and ensures that your brand is visible. We offer silk-screen printing and embossing, both of which are durable and long-lasting, even at ultra-low temperatures.

Custom labeling isn't just about branding; it's about efficiency. Imagine having your lab's name and contact information on every tube—this makes it easy to return lost samples or identify where they came from. For clinical trials, custom labeling can include patient IDs or study numbers, which helps with tracking and compliance.

Custom Mold Design for Plastic Bottles

If our standard models don't fit your needs, we offer custom mold design for plastic bottles. Our team of engineers will work with you to create a cryotube that fits your specific requirements—whether it's a unique volume, a special thread type, or a custom shape. We offer free mold testing, so you can see a prototype before we start mass production. This ensures that the custom design works perfectly with your equipment and storage systems.

Custom mold design is ideal for labs that have unique storage racks or equipment. For example, if your freezer has a specific size requirement, we can design a tube that fits perfectly. We also offer custom colors, so you can color-code your samples for easy organization. Whether you need a bright red tube for hazardous samples or a blue tube for control samples, we can make it happen.

Sustainable Options

We're committed to reducing our environmental impact, which is why we offer sustainable plastic packaging solutions. Our PCR plastic cryotubes are made from recycled polypropylene, which reduces the amount of new plastic used. These tubes are just as durable and high-quality as our standard tubes, but they have a lower carbon footprint. We also offer recyclable packaging for our products, so you can dispose of the packaging in an eco-friendly way.

Quality You Can Trust: Certifications & Manufacturing Standards

At our ISO9001 certified packaging factory, quality isn't an afterthought—it's built into every step of the manufacturing process. Our dust-free GMP compliant workshop is designed to minimize any risk of contamination. Every cryotube is made from medical-grade polypropylene (PP) that's resistant to extreme temperatures and chemicals.

Before any cryotube leaves our factory, it undergoes a series of rigorous tests. First, we check for leaks: each tube is submerged in liquid and pressurized to ensure no air or liquid can get in or out. Then, we test for sterility using EO (ethylene oxide) or gamma radiation, depending on the product. Non-pyrogenic testing is done to ensure there are no endotoxins present, which could cause fever or adverse reactions if the tube comes into contact with biological samples.

Our GMP compliant workshop is equipped with state-of-the-art machinery that ensures consistent quality. We use automated processes to mold and assemble the tubes, which reduces human error. Every batch is tested for quality, and we keep detailed records of every step of the manufacturing process. This allows us to trace any issues back to their source and make improvements quickly.
