Vitrification
Definition:
(n.) Same as Vitrifaction.
Example Sentences:
(1) Included in the thermal destruction category are treatment technologies such as rotary kiln incineration, fluidized bed incineration, infrared thermal treatment, wet air oxidation, pyrolytic incineration, and vitrification.
(2) The purpose of the present survey is to show that a general understanding of the physical behavior and biological effects of vitrification solutions, as well as an understanding of the conditions under which vitrification solutions are required, is gradually emerging.
(3) The embryos were transferred to an equilibration medium [10% 1,2-propanediol and 20% glycerol in modified PBS (mPBS)] for 10 minutes and frozen in a vitrification medium (25% glycerol and 25% 1,2-prapanediol in mPBS) by direct lowering into liquid nitrogen.
