Autoclavable Cryo Tubes: Sterile, Pyrogen-Free & Ready-to-Use

Let's be honest—when you're working in a lab or managing a biobank, the last thing you want to worry about is whether your sample storage tubes are up to the task. You've spent hours collecting, processing, and analyzing precious biological materials—cells, DNA, blood samples, or vaccine aliquots—and the thought of losing them to a leaky tube or contaminated storage solution is enough to keep anyone up at night. That's where autoclavable cryo tubes come in: they're the unsung heroes of the lab, designed to keep your samples safe, sterile, and intact even in the harshest conditions.

At our core, we're a cryogenic tubes manufacturer that's been in the business for years, and we know exactly what researchers need. Our autoclavable cryo tubes aren't just any storage containers—they're built to meet the strictest standards for sterility, durability, and performance. Whether you're storing samples in liquid nitrogen or autoclaving them for reuse, these tubes have got you covered.

Let's dive into the features that make our autoclavable cryo tubes stand out from the crowd. Each feature is designed with your needs in mind—so you can focus on your research, not your storage solutions.

One of the biggest advantages of our tubes is that they're autoclavable. For those who might not know, autoclaving is a process that uses high heat (121°C) and pressure (15 psi) to kill bacteria, viruses, and other contaminants. This means you can reuse our tubes multiple times (as long as they're not cracked or damaged) without worrying about cross-contamination.

Why does this matter? Well, if you're running a lab on a budget, reusing tubes can save you a lot of money over time. And even if cost isn't an issue, being able to autoclave means you can ensure that every tube you use is 100% sterile—critical for experiments that require absolute purity.

Every single one of our autoclavable cryo tubes comes pre-sterilized and pyrogen-free. Let's break that down:

There's nothing more frustrating than losing a sample to a leaky tube. That's why our leak-proof cryotubes with silicone gasket are a game-changer. The silicone gasket creates an airtight seal that doesn't break even when exposed to extreme temperatures—like the -196°C of liquid nitrogen.

We've tested these gaskets time and time again. Whether you're storing tubes in liquid nitrogen or transporting them from one lab to another, you can rest easy knowing that your samples won't leak out or get contaminated by external substances.

Our sterile cryo vials for liquid nitrogen are designed to handle the extreme cold of liquid nitrogen storage. Liquid nitrogen is often used for long-term storage of biological samples because it keeps them at a temperature of -196°C —a temperature where all biological activity stops, preserving the sample's integrity for years (or even decades).

The material we use for our tubes—polypropylene (PP)—is perfect for this. PP has low thermal conductivity, which means it doesn't crack or break when exposed to sudden temperature changes. So whether you're putting a tube straight from room temperature into liquid nitrogen or taking it out to thaw, it won't shatter.

Our tubes are made from high-quality PP that's resistant to most chemicals. This means you can store a wide range of samples—from DNA and RNA to proteins and cell cultures—without worrying about the tube reacting with the sample.

PP is also very durable. It can withstand being dropped (though we don't recommend it!) and can handle repeated autoclaving cycles without degrading.

Our autoclavable cryo tubes are versatile and can be used in a wide range of applications. Let's take a look at some of the most common ones:

Biobanks are facilities that store biological samples for future research or clinical use. They need storage solutions that are reliable and can keep samples intact for years. Our tubes are perfect for this—they're leak-proof, sterile, and can handle long-term storage in liquid nitrogen.

Whether you're storing human blood samples, animal tissues, or plant seeds, our tubes will keep them safe and sound.

Clinical researchers often need to store samples like DNA, RNA, or biopsy tissues for analysis. Our tubes are sterile and pyrogen-free, so they won't contaminate the samples. And since they're autoclavable, researchers can reuse them for multiple experiments.

Vaccines are some of the most sensitive biological materials. Many vaccines require ultra-cold storage to remain effective. Our -196°C cryogenic storage tubes are perfect for this—they can keep vaccines intact for long periods of time.

Agricultural researchers often store plant seeds or genetic material for crop improvement. Our tubes are durable and can handle the extreme cold of liquid nitrogen, making them ideal for this application.

Veterinary clinics and research facilities store animal samples for disease testing or breeding programs. Our tubes are sterile and leak-proof, so they're perfect for storing these samples.

There are a lot of cryogenic tube manufacturers out there, but we believe we stand out for a few key reasons:

Choosing the right autoclavable cryo tube depends on a few factors. Let's go through them:

The first thing you need to consider is the volume of your sample. If you're storing small samples (like DNA aliquots), a 0.5ml or 1.8ml tube is perfect. For larger samples (like blood or tissue), you might need a 5ml or 10ml tube.

Our tubes come with either internal or external threads. Internal threads are better for tight sealing, while external threads are easier to handle (especially if you're wearing gloves). Think about your workflow and choose the thread type that works best for you.

If you plan to reuse your tubes, make sure you choose autoclavable ones. Our tubes are all autoclavable, so you don't have to worry about this—but it's always a good idea to double-check.

If you need ready-to-use tubes, choose pre-sterilized ones. Our tubes are all pre-sterilized, so you can start using them right away.

If you're storing samples in liquid nitrogen, make sure your tubes are compatible with -196°C temperatures. Our tubes are designed for this, so you're good to go.

To get the most out of your autoclavable cryo tubes, follow these tips:
