When it comes to transporting biological samples, vaccines, or other perishable items that need to be stored at extremely low temperatures, a liquid nitrogen shipper is an essential tool. These specially designed containers are equipped to maintain the required temperature for extended periods, ensuring that the contents remain frozen and intact throughout the shipping process.
What is a liquid nitrogen shipper?
A liquid nitrogen shipper is a portable container that is used to transport items that need to be kept at cryogenic temperatures, typically below -150 degrees Celsius. These shippers are insulated to prevent heat transfer and are filled with liquid nitrogen to maintain the necessary low temperature. They are commonly used in scientific research, medical laboratories, and the biotechnology industry for transporting biological samples, cell cultures, DNA, and vaccines.
How does a liquid nitrogen shipper work?
Liquid nitrogen is a colorless, odorless, and tasteless cryogenic liquid that boils at -196 degrees Celsius. When stored in a vacuum-insulated container like a liquid nitrogen shipper, it can keep the interior temperature at cryogenic levels for several days or even weeks. The insulation prevents heat from entering the container, while the liquid nitrogen continuously evaporates to maintain the low temperature.
liquid nitrogen shippers are equipped with a pressure relief valve to prevent the buildup of excess pressure caused by the evaporation of the liquid nitrogen. This ensures that the container remains sealed and secure during transportation. Some shippers also come with temperature monitoring devices to allow users to track the temperature inside the container in real-time.
Why use a liquid nitrogen shipper?
liquid nitrogen shippers offer several advantages over traditional refrigeration methods when it comes to transporting items that need to be kept at cryogenic temperatures. Here are some of the main benefits of using a liquid nitrogen shipper:
1. Portability: liquid nitrogen shippers are portable and can be carried to remote locations without the need for electricity or additional cooling systems.
2. Long-lasting temperature control: Liquid nitrogen can maintain a consistent low temperature for an extended period, making it ideal for long-distance shipping.
3. Safe and secure: Liquid nitrogen shippers are designed to prevent leaks and spills, ensuring that the contents remain safe and secure during transportation.
4. Versatile: Liquid nitrogen shippers can be used to transport a wide range of items, including biological samples, vaccines, and other perishable materials that require cryogenic storage.
5. Cost-effective: Liquid nitrogen is a relatively inexpensive cryogen compared to other alternatives, making liquid nitrogen shippers a cost-effective option for transporting sensitive items.
Applications of liquid nitrogen shippers
Liquid nitrogen shippers are used in a variety of industries and settings where maintaining cryogenic temperatures is essential. Some common applications of liquid nitrogen shippers include:
1. Biomedical research: Liquid nitrogen shippers are used to transport biological samples, cell cultures, and genetic materials for research purposes.
2. Medical laboratories: Liquid nitrogen shippers are used to transport vaccines, blood samples, and other biological materials that need to be stored at low temperatures.
3. Assisted reproduction: Liquid nitrogen shippers are used to transport sperm, eggs, and embryos for in vitro fertilization procedures.
4. Food industry: Liquid nitrogen shippers are used to transport frozen food products and ingredients that need to be kept at cryogenic temperatures.
5. Veterinary medicine: Liquid nitrogen shippers are used to transport samples for diagnostic testing and medical research in veterinary clinics and laboratories.
In conclusion, liquid nitrogen shippers are essential tools for maintaining the integrity of sensitive materials that need to be stored at cryogenic temperatures during transportation. Whether you are a scientist, researcher, medical professional, or food industry worker, having access to a reliable liquid nitrogen shipper can make all the difference in ensuring the safety and security of your valuable samples and products. So, the next time you need to transport perishable items at extremely low temperatures, consider using a liquid nitrogen shipper to keep them safe and secure throughout the shipping process.
