Because the process happens so fast, freezing the cream with
liquid nitrogen creates smaller water crystals than traditional
methods and less air whip is needed, resulting in a richer product.
The traditional
method requires the sequential addition of cryoprotectants over a series of 10 to 20 minutes and then an approximately two hour process that cools the cells at about 0.3 to two degrees a minute down to -196 degrees Celsius, which is the temperature of
liquid nitrogen.
The CryoCrate
method allows researchers to preserve cells at much higher temperatures (even to -20 °C), he says, adding that they don't require the use of
liquid nitrogen and have the potential to save costs.
3) Cryotherapy is a treatment
method that involves the freezing off of warts using
liquid nitrogen.
Professor Davis and colleagues have suggested a new
method using an ionic
liquid based on
nitrogen that could avoid these issues.
