Industry Knowledge

Plastic cryogenic tubes, also known as cryovials, are specialized containers designed to store biological specimens, typically at very low temperatures, such as in cryogenic storage. These tubes are crucial tools in various fields of scientific research, biotechnology, and clinical applications, ensuring the preservation and long-term storage of sensitive biological materials like cells, tissues, DNA, RNA, and proteins.
The construction of plastic cryogenic tubes is carefully engineered to withstand extreme cold temperatures and preserve the integrity of the stored biological samples. These tubes are typically made of high-quality polypropylene, a material known for its excellent chemical resistance, durability, and low-temperature tolerance. Polypropylene ensures that the tubes remain intact and do not become brittle or crack when exposed to extremely low temperatures.
A crucial feature of plastic cryogenic tubes is their airtight and leak-proof sealing mechanism. The caps of these tubes are designed to create a secure seal, preventing any potential leakage that could compromise the samples stored within. This feature is particularly important when dealing with cryogenic storage, as any compromise in sealing can lead to sample degradation and contamination.
The cap design of plastic cryogenic tubes often includes an external thread to facilitate easy and secure closure, ensuring a tight seal and preventing any possibility of air or moisture infiltration. Some caps also have silicone gaskets, enhancing the seal's efficiency and providing an extra layer of protection against potential contamination.
To enhance sample traceability and organization, plastic cryogenic tubes often have an area for labeling or marking. This allows researchers to record essential information such as sample type, date of collection, and any other relevant details. Clear, molded graduations on the tube's body aid in precise measurement and sample volume identification.
Plastic cryogenic tubes come in various sizes and volumes to accommodate different quantities of biological samples. These volumes typically range from a few milliliters to several milliliters, providing flexibility in sample storage based on the specific needs of the research or clinical application.
One of the primary applications of plastic cryogenic tubes is the storage of cell cultures and biological specimens for long-term preservation. Maintaining the viability of these samples is critical for ongoing research, diagnostics, and therapeutic development. The ability of these tubes to endure cryogenic temperatures ensures the safe storage of samples for extended periods, sometimes decades, without compromising their quality.
In addition to biological specimens, plastic cryogenic tubes are widely used for the storage of molecular materials such as DNA, RNA, and proteins. This is particularly important in genetic research and biotechnology, where the preservation of genetic material at ultra-low temperatures is fundamental to maintaining sample integrity and preventing degradation.
Furthermore, plastic cryogenic tubes play a pivotal role in the field of assisted reproductive technology (ART). Sperm, oocytes, embryos, and other reproductive materials are often cryopreserved using these tubes, allowing individuals or couples to preserve their fertility for future use.
Plastic cryogenic tubes are essential tools in scientific research, biotechnology, and clinical settings. Their robust construction, airtight sealing mechanisms, and compatibility with ultra-low temperatures make them indispensable for the preservation and storage of valuable biological samples. These tubes ensure that researchers and clinicians can maintain the integrity and viability of biological materials, advancing scientific knowledge and improving medical outcomes.
