title: [Cryofractures of biological material performed at very low temperatures in ultravacuum].
abstract: A new instrument has been designed for freeze-fracturing of biological material in ultra high vacuum. Complementary replicas of the freeze-fracture faces can be done at a temperature reaching to --260 degrees C in a short time, without any contamination of fracture faces being observed.
