If you work in a laboratory or clinic that relies on cryogenic storage, you know how important it is to have a reliable system for transporting and storing biological samples at ultra-low temperatures. This is where a liquid nitrogen shipper comes in.

A liquid nitrogen shipper is a specialized container that is designed to safely transport and store biological samples at temperatures as low as -190 degrees Celsius. This is achieved by using liquid nitrogen as the coolant, which is extremely cold and can maintain stable temperatures for extended periods of time.

Here are some key things you need to know about liquid nitrogen shippers:

1. How do they work?

liquid nitrogen shippers work by using liquid nitrogen as a coolant. The samples are placed inside the shipper, and liquid nitrogen is added to cool the samples down to the desired temperature. The shipper is then sealed, and the liquid nitrogen evaporates slowly, maintaining the low temperature inside the container.

2. Why are they important?

liquid nitrogen shippers are essential for transporting and storing biological samples that are sensitive to temperature fluctuations. In many cases, these samples need to be kept at ultra-low temperatures to prevent degradation or spoilage. liquid nitrogen shippers provide a reliable way to transport these samples without compromising their integrity.

3. Types of liquid nitrogen shippers

There are several types of liquid nitrogen shippers available on the market, including portable dewars, dry shippers, and vapor shippers. Portable dewars are small, lightweight containers that are used for short-term storage and transport of samples. Dry shippers use an absorbent material to soak up liquid nitrogen, allowing for longer shipping times. Vapor shippers use a special design to maintain a constant temperature, making them ideal for long-distance transport.

4. Considerations when choosing a liquid nitrogen shipper

When choosing a liquid nitrogen shipper, there are several factors to consider. The size of the shipper will depend on the volume of samples you need to transport. You should also consider the duration of transportation and the temperature stability of the shipper. It’s important to choose a shipper that meets your specific needs and requirements.

5. Proper handling and maintenance

Proper handling and maintenance of liquid nitrogen shippers are essential to ensure the safety of the samples and the user. Make sure to always wear appropriate protective equipment when handling liquid nitrogen, as it can cause frostbite on contact with skin. Additionally, regular maintenance of the shipper, such as checking for leaks and topping up the liquid nitrogen, is crucial to prevent temperature fluctuations.

In conclusion, liquid nitrogen shippers are a vital tool for anyone working with biological samples that require ultra-low temperatures for storage and transport. By understanding how they work, the different types available, and the considerations for choosing the right shipper, you can ensure the safety and integrity of your samples. Remember to always handle liquid nitrogen with care and maintain your shipper properly to prevent any potential issues.
