Cryogenic dry shippers are an essential tool in transporting biological samples, tissues, and other temperature-sensitive materials at ultra-low temperatures. These innovative containers use liquid nitrogen to maintain a consistent low temperature, ensuring the integrity and viability of the shipped materials. In this article, we will explore the features, benefits, and applications of cryogenic dry shippers, also referred to as cryogenic shipping containers or liquid nitrogen shippers.
What is a cryogenic dry shipper?
A cryogenic dry shipper is a vacuum-insulated container designed to hold and transport materials at cryogenic temperature levels, typically below -150°C. These containers come in various sizes and shapes, with the most common ones resembling a thermos flask or a cylindrical chamber. The critical component of a cryogenic dry shipper is a dewar flask, which holds the liquid nitrogen and maintains a consistent low temperature inside the container.
How Does a cryogenic dry shipper Work?
The working principle of a cryogenic dry shipper is relatively simple yet highly effective. Liquid nitrogen is stored in the dewar flask, which is inside the vacuum-insulated outer shell of the container. The vacuum insulation minimizes heat transfer from the external environment, allowing the liquid nitrogen to keep the interior temperature below -150°C for an extended period. The samples or materials to be transported are placed inside the container, surrounded by the cold vapor of liquid nitrogen, ensuring they remain frozen during transit.
Benefits of Using a cryogenic dry shipper
There are several benefits to using a cryogenic dry shipper for transporting temperature-sensitive materials:
1. Maintain Sample Integrity: The ultra-low temperatures maintained by cryogenic dry shippers ensure that biological samples, tissues, and other materials are preserved in their original state without degradation.
2. Long-Term Storage: Cryogenic dry shippers can keep samples frozen for days or even weeks, making them ideal for transporting materials over long distances or extended periods.
3. Cost-Effective: Compared to other cold chain transportation methods, cryogenic dry shippers are a cost-effective solution for maintaining sample integrity without the need for specialized refrigeration units.
4. Easy to Use: Cryogenic dry shippers are user-friendly and do not require any power source or complex setup, making them convenient for transportation in remote locations or during fieldwork.
Applications of Cryogenic Dry Shippers
Cryogenic dry shippers have a wide range of applications across various industries and fields, including:
1. Biomedical Research: Cryogenic dry shippers are commonly used to transport biological samples, tissues, and vaccines for research purposes, ensuring the integrity and viability of the materials.
2. Assisted Reproductive Technology: Cryogenic dry shippers are essential for the safe transportation of frozen embryos, sperm, and eggs for fertility treatments and reproductive technologies.
3. Pharmaceutical Industry: Pharmaceutical companies use cryogenic dry shippers to transport temperature-sensitive drugs, vaccines, and other medical products that require ultra-low temperatures for stability.
4. Agricultural Science: Cryogenic dry shippers are employed in the shipping of plant samples, seeds, and genetic materials for crop improvement and biodiversity conservation.
In conclusion, cryogenic dry shippers are indispensable tools for transporting temperature-sensitive materials at ultra-low temperatures, ensuring the integrity and viability of the shipped samples. These containers provide a cost-effective, reliable, and easy-to-use solution for maintaining the cold chain during transportation, making them essential for various industries and applications. Whether in biomedical research, pharmaceuticals, assisted reproductive technology, or agricultural science, cryogenic dry shippers play a crucial role in safeguarding the quality of transported materials.
