(medicine) An experimental procedure for preserving human organs in which chemicals are added prior to cooling to prevent crystallization of water within and outside the cells, so that with coolings the molecules essentially become fixed in place.

Vitrification technologies for the treatment of contaminated soil. But some researchers have developed a preservation technique called vitrification, essentially glassifying cells. Pristane is a branched alkane of a slightly higher molecular mass than the normal hexadecane; the branching prevents crystallization or vitrification down to -60[degrees]C, while the higher molecular mass reduces the rate of evaporation of pristane as compared to normal hexadecane. |
