Abstract: A device, in particular for a biological sample grinding apparatus, comprising a first enclosure comprising an internal chamber intended to receive a material capable of producing cold by sublimation under normal temperature and pressure conditions and comprising an opening making it possible for a fluidic communication with an internal chamber of a second enclosure through an opening of it. The device further comprising an air circuit making the outside air communicate with the internal chamber of the first enclosure, a blasting module making it possible for an air circulation in the air circuit from the outside up into the internal chamber of the first enclosure.

Abstract: The invention relates to a device, in particular for a biological sample grinding apparatus, comprising a first enclosure (18) comprising an internal chamber (32) intended to receive a material (57) capable of producing cold by sublimation under normal temperature and pressure conditions and comprising an opening (30) making it possible for a fluidic communication with an internal chamber of a second enclosure (20) through an opening (36) of it, the device further comprising an air circuit making the outside air communicate with the internal chamber (32) of the first enclosure (18), blasting means (76) making it possible for an air circulation in the air circuit from the outside up into the internal chamber (32) of the first enclosure (18).

Abstract: Apparatus for grinding biological samples contained in tubes (12) carried by a turntable (10) driven with oscillating motion, the zone in which the tubes (12) oscillate being surrounded by cooling means (30) enabling the samples in the tubes (12) to be maintained at a desired low temperature, e.g. 4° C., while they are being ground.
