Sterile Cryogenic Tubes for Lab Use – Ready-to-Use Packaging

When it comes to preserving sensitive biological samples in a laboratory setting, the choice of storage containers can make all the difference between successful research outcomes and costly failures. Whether you're working with cell cultures, DNA samples, vaccines, or other delicate materials, having reliable, sterile cryogenic tubes is non-negotiable. These tubes are designed to withstand the extreme temperatures of liquid nitrogen storage (-196°C) while keeping your samples contamination-free. As a leading cryogenic tubes manufacturer, we understand the critical role these products play in scientific research, and we've engineered our sterile cryo vials to meet the highest standards of quality and performance.

The Importance of Sterile Cryogenic Storage

Biological samples are incredibly sensitive to external contaminants like bacteria, fungi, or even trace amounts of enzymes such as DNase or RNase. A single contamination event can render months of research useless, not to mention the financial implications of lost samples and delayed projects. That's why sterility is the top priority when it comes to cryogenic tubes. Our sterile cryo vials for liquid nitrogen are manufactured in dust-free GMP compliant workshops, ensuring that every tube is free from contaminants before it reaches your lab.

Moreover, the extreme temperatures involved in cryogenic storage (-196°C) demand that the tubes are not only sterile but also structurally sound. Any leak or crack in the tube can lead to sample loss or cross-contamination. Our -196°C cryogenic storage tubes are built to withstand these harsh conditions, with features like leak-proof seals and durable materials that maintain integrity even after repeated freeze-thaw cycles.

Key Features of Our Sterile Cryogenic Tubes

Let's take a closer look at what sets our cryogenic tubes apart from the competition:

1. Uncompromising Sterility

All our cryogenic tubes are pre-sterilized using either ethylene oxide (EO) or gamma irradiation, two methods that are widely recognized for their effectiveness in eliminating microorganisms. Each batch undergoes rigorous sterility testing to ensure compliance with medical grade standards. Additionally, our tubes are DNase/RNase-free and non-pyrogenic, making them ideal for sensitive molecular biology applications.

2. Leak-Proof Design

One of the most common issues with cryogenic tubes is leakage, which can occur due to poor sealing or material failure. Our leak-proof cryotubes with silicone gasket address this problem head-on. The silicone gasket creates an airtight seal that prevents liquid nitrogen from entering the tube and protects the sample from contamination. Whether you're storing samples vertically or horizontally, you can trust that our tubes will keep your samples safe.

3. Durable Materials

We use high-quality polypropylene (PP) plastic for our cryogenic tubes, which is known for its excellent low-temperature resistance and chemical stability. PP can withstand temperatures as low as -196°C without becoming brittle, ensuring that the tubes don't crack during storage or when being removed from liquid nitrogen. This durability also means that our tubes can be reused (if sterilized properly) or disposed of safely as disposable cryogenic vials wholesale.

4. Versatile Sizes and Configurations

Every lab has unique needs, which is why we offer a wide range of cryogenic tube sizes and configurations. Here's a breakdown of our available options:

Size (ml)	Thread Type	Bottom Type	Sterility	Packaging
0.5ml	Internal	Conical	Pre-sterilized	Bulk (1000/pack)
1.8ml	Internal/External	Conical/Round	Pre-sterilized	Bulk (500/pack) or Individual
2ml	Internal	Conical	Pre-sterilized	Bulk (500/pack)
5ml	External	Round	Pre-sterilized	Bulk (200/pack)

Each tube comes with a writable surface or optional barcode labels, making sample tracking easy and efficient. The conical bottom design is perfect for pelleting cells, while the round bottom is suitable for general storage.

5. Customization Options

As a leading OEM plastic container manufacturer, we understand that some labs have specific requirements that off-the-shelf products can't meet. That's why we offer custom mold design for plastic bottles and containers, including cryogenic tubes. Whether you need a unique size, a special closure mechanism, or custom branding, our team of engineers can work with you to create a solution that fits your needs. We also offer private label plastic packaging, allowing you to add your lab's logo or name to the tubes for a professional touch.

Manufacturing Process and Quality Control

Our manufacturing facilities are ISO 9001 certified packaging factories, which means that every step of the production process is governed by strict quality control standards. From raw material selection to final packaging, we adhere to the highest industry practices to ensure that our products are consistent and reliable.

Dust-Free GMP Compliant Workshops

All our cryogenic tubes are manufactured in dust-free GMP compliant workshops. These controlled environments minimize the risk of contamination during production, ensuring that every tube is as clean as possible before sterilization. Our staff follows strict hygiene protocols, including wearing protective clothing and using sterile equipment, to maintain the integrity of the production process.

Raw Material Testing

We source our polypropylene plastic from trusted suppliers who provide material certificates. Each batch of raw material is tested for chemical composition and low-temperature resistance to ensure that it meets our quality standards. Only materials that pass these tests are used in production.

Production and Assembly

Our production lines are automated to reduce human error and ensure consistency. The tubes are molded, assembled with the silicone gasket, and then sterilized. After sterilization, each batch is tested for sterility using methods like membrane filtration and incubation. Any batch that fails these tests is rejected and disposed of properly.

Packaging and Shipping

Once the tubes pass all quality control checks, they are packaged in sterile, tamper-evident containers to maintain their sterility during shipping. We offer both bulk and individual packaging options to suit your lab's needs. As a China plastic bottle exporter, we can ship our products to labs around the world, with fast and reliable delivery times.
