Cryogenic freezers are special types of refrigerators that are used to store materials at very cold temperatures, typically below -150°C. These materials can include biological samples, pharmaceuticals, and other sensitive materials that need to be kept at low temperatures.
What do they do:
- Cryogenic freezers are typically much larger than standard fridges and freezers, and they use liquid nitrogen or liquid helium to keep their contents cold.
- In addition to providing storage for sensitive materials, cryogenic freezers can also be used for cooling down other equipment, such as lasers.
- As a result, these versatile pieces of equipment are an essential part of many laboratories and research facilities.
The benefits of owning a cryogenic freezer:
- A cryogenic freezer is an essential piece of equipment for any laboratory or research facility that needs to store large quantities of biological samples.
- Cryogenic freezing is a process that uses extremely cold temperatures to preserve samples for long-term storage.
- While most freezers can only reach -20 degrees Celsius, cryogenic freezers can achieve temperatures as low as -196 degrees Celsius.
- In addition, cryogenic freezing can be used to preserve delicate samples that would be damaged by other methods of storage.
How to choose the right cryogenic freezer for your needs:
When it comes to storing samples at cryogenic temperatures, choosing the right freezer is essential. There are a few key factors to consider when making your decision.
- First, consider the capacity of the freezer. How many samples will you need to store?
- Second, think about the type of samples you’ll be storing. Are they sensitive to changes in temperature, or does it matter?
- Finally, take into account the budget for your freezer.
- Once you’ve considered all of these factors, you’ll be able to choose the right cryogenic freezer for your needs.
The different types of cryogenic freezers available on the market:
- The most common type of cryogenic freezer is the liquid nitrogen freezer, which uses liquid nitrogen to cool samples down to -196 degrees Celsius.
- A newer option is the solid-state freezer, which uses a cooling element made of porous silicon to cool samples down to -269 degrees Celsius.
- And finally, there is the immersion freezer, which immerses samples in a cold bath of liquid helium to cool them down to -452 degrees Celsius.
Endnote:
When it comes to cryogenic freezing, these are some of the few different options available on the market. Each type of cryogenic freezer has its own advantages and disadvantages, so it’s important to choose the one that’s right for your needs.
