Lypholization
« on: April 15, 2008, 01:21:03 PM »
In the experimental section of some papers I have read, I have come across the term "lypholization."  I do not remember ever learning about that as an undergrad.  Could anybody explain to me what it is and what it is used for?

This means freeze drying. An aqueous solution is shell frozen at -196 deg C (ie liquid nitrogen temperature) and then pumped on a vacuum manifold. This slowly removes the water and usually leaves a nice dry, fluffy solid.
