Freezing occurs in two steps, a first non-destructive freezing event and a second independent lethal event. Localization of ice, and whether cells freeze-dehydrate after the first freezing event remains unknown. The cause of frost damage during the second …

Osmolality Measurement Advanced Instruments

WebMeasurement of osmotic pressure method is preferred for the determination of molar masses of macromolecules such as proteins and polymers. This is due to the following … WebΦ = osmotic coefficient, which accounts for the degree of molecular dissociation. n = number of particles into which a particle can dissociate.
