What Are Pre-Sterilized Cryogenic Vials?
Pre-sterilized cryogenic vials are specialized containers used to store biological samples at ultra-low temperatures (down to -196°C). Unlike regular plastic containers, these vials are made from high-quality polypropylene (PP) that can withstand extreme cold without becoming brittle or cracking. They are also pre-sterilized using either ethylene oxide (EO) or gamma radiation, eliminating the need for labs to sterilize them before use—saving time and reducing the risk of contamination.
The key features of our pre-sterilized cryogenic vials include:
-
Ultra-low temperature resistance (-196°C) for liquid nitrogen storage
-
Leak-proof design with medical-grade silicone gaskets
-
Pre-sterilized to ensure no microbial contamination
-
Available in multiple sizes and thread types to fit different storage systems
-
Clear labeling areas for easy sample identification
These vials are essential for a wide range of applications, including biobanking, clinical diagnostics, vaccine storage, cell culture research, and reproductive medicine. For example, in biobanking, our -196°C cryogenic storage tubes are used to store stem cells, blood samples, and tissue specimens for decades, preserving their viability for future use in therapies or research.
Our Sterilization Processes: EO vs. Gamma Radiation
Sterility is non-negotiable when it comes to cryogenic storage. That's why we offer two sterilization options—ethylene oxide (EO) and gamma radiation—each with its own benefits. Let's take a closer look at both:
Ethylene Oxide (EO) Sterilization
EO sterilization is a chemical process that uses ethylene oxide gas to kill bacteria, viruses, and fungi. It's ideal for plastic containers because it penetrates deeply into the material without causing heat damage. Our EO sterilization process involves:
-
Sealing vials in airtight packages
-
Exposing them to controlled concentrations of EO gas
-
Aerating the vials to remove any residual gas (ensuring they are safe for use)
Benefits of EO sterilization:
-
Compatible with all plastic materials (no brittleness or discoloration)
-
Effective against all types of microbes
-
Suitable for small batches and custom orders
Gamma Radiation Sterilization
Gamma radiation sterilization uses high-energy gamma rays to destroy microbial DNA, ensuring complete sterilization. It's a fast, efficient process that's ideal for large batches. Our gamma sterilization process involves:
-
Packaging vials in bulk containers
-
Exposing them to controlled doses of gamma radiation from a cobalt-60 source
-
Testing samples from each batch to confirm sterility
Benefits of gamma sterilization:
-
No residual chemicals (safe for sensitive samples)
-
Fast processing time for large orders
-
Uniform sterilization across all vials in a batch
We let our customers choose the sterilization method that best fits their needs. For labs that prioritize no chemical residues, gamma is the way to go. For those who need custom-sized vials or small batches, EO sterilization is more flexible. Either way, you can trust that our vials are 100% sterile and ready to use.

One of our most popular features is the
leak-proof cryotubes with silicone gasket. The gasket is made from medical-grade silicone that forms an airtight seal even at -196°C, preventing liquid nitrogen from entering the vial and sample from leaking out. This is crucial for maintaining sample integrity and avoiding cross-contamination in storage tanks.
Applications of Our Pre-Sterilized Cryogenic Vials
Our cryogenic vials are used in a wide range of industries and research fields. Let's explore some of the most common applications:
Biobanking
Biobanks store millions of biological samples for future research and clinical use. Our -196°C cryogenic storage tubes are ideal for this purpose because they can preserve samples like stem cells, blood, and tissue for decades. For example, a biobank focused on cancer research might use our vials to store tumor samples from patients, allowing researchers to study the progression of the disease over time. Our
disposable cryogenic vials wholesale options are perfect for biobanks that need large quantities of vials at an affordable price.
Clinical Laboratories
Clinical labs rely on cryogenic vials to store diagnostic samples like blood, urine, and saliva. Pre-sterilized vials eliminate the risk of contamination, ensuring accurate test results. For example, a lab testing for genetic disorders might use our vials to store DNA samples, as the ultra-low temperature preserves the DNA's structure. Our EO-sterilized vials are particularly popular in clinical labs because they are compatible with sensitive diagnostic equipment.
