If you work in the field of biology, chemistry, or any other industry that requires the storage and transportation of samples at extremely low temperatures, then you are probably familiar with cryo shippers. These specialized containers are designed to keep samples frozen at cryogenic temperatures during shipping, ensuring that they arrive at their destination in perfect condition. In this article, we will take an in-depth look at cryo shippers, how they work, and why they are essential for any organization that deals with frozen samples.
What is a cryo shipper?
A cryo shipper is a container specially designed to transport materials at ultra-low temperatures, typically around -196°C (-320°F), using liquid nitrogen as the refrigerant. These shippers are commonly used to transport biological samples, genetic material, organs for transplant, and other sensitive materials that need to be kept frozen during shipping. Cryo shippers are typically made of materials that can withstand the extreme cold temperatures, such as stainless steel or durable plastics.
How Does a cryo shipper Work?
Cryo shippers rely on liquid nitrogen to keep samples frozen during transportation. Liquid nitrogen has a boiling point of -196°C (-320°F), making it ideal for keeping samples at ultra-low temperatures. The cryo shipper is filled with liquid nitrogen, which creates a cold vapor that keeps the samples frozen. The samples are typically stored in vials or containers that are placed inside the cryo shipper. The shipper is then sealed to prevent any leaks or spills during transportation.
Why are cryo shippers Important?
Cryo shippers play a crucial role in ensuring that sensitive samples arrive at their destination in optimal condition. Without proper refrigeration, samples can degrade or become unusable, compromising the integrity of the research or experimentation being conducted. Cryo shippers provide a reliable and secure method of transporting samples at ultra-low temperatures, giving researchers peace of mind that their materials are safe during transit.
Types of Cryo Shippers
There are several different types of cryo shippers available, each designed for specific applications and quantities of samples. Some common types of cryo shippers include:
1. Dewar flasks: These are cylindrical containers with a double-walled design that provides excellent insulation for samples stored in vials or containers.
2. Dry shippers: These shippers use a special absorbent material to prevent spills and leaks of liquid nitrogen during transportation, making them ideal for longer journeys.
3. Portable cryo shippers: These shippers are designed for transporting smaller quantities of samples and are typically lightweight and easy to carry.
Tips for Using Cryo Shippers
When using cryo shippers, it is essential to follow proper procedures to ensure the safety of both the samples and the individuals handling them. Here are some tips for using cryo shippers effectively:
1. Always wear appropriate personal protective equipment, such as gloves and goggles, when handling cryo shippers.
2. Check the seals and insulation of the cryo shipper before each use to ensure that it is in good condition.
3. Handle the cryo shipper with care to prevent spills or leaks of liquid nitrogen.
4. Do not open the cryo shipper while it is in transit, as this can compromise the temperature inside the container.
5. Follow the manufacturer’s instructions for filling and sealing the cryo shipper to ensure that samples remain frozen during transportation.
In Conclusion
Cryo shippers are essential tools for any organization that deals with frozen samples. These specialized containers provide a reliable and secure method of transporting materials at ultra-low temperatures, ensuring that samples arrive at their destination in perfect condition. By understanding how cryo shippers work and following proper procedures for handling and using them, researchers can maintain the integrity of their samples and conduct experiments with confidence.
