Abstract
SUMMARYWe have developed a temperature controlled specimen stage on the existing jet‐freezing apparatus, in order to quench samples from elevated temperatures up to 330 K. We have shown that the phase transition both from the liquid‐crystalline to solid phase for pure phosphatidylcholines and from hexagonal II to lamellar phase for phosphatidylethanolamine/4% egg phosphatidic acid is prevented. Moreover, cooling rates exceeding 10,000 K s—1 were recorded indicative of ultra‐rapid freezing capacity. Cryoprotectants can be omitted, since phase separation due to ice crystal growth does not occur.
