<p>The apparatus for grinding biological samples contained in tubes (12), comprises a plate (10) for supporting the tubes, a unit for forcing the plate in oscillatory motion around a center of rotation located on an axis of the plate, a unit for cooling the tubes are carried by a part of the apparatus and surround the plate for defining a cooling zone having the tube oscillation zone carried by the plate, an air evacuation canal, a fitting type automatic multiple clamp, and an annular hood. The cooling unit (30) comprises an annular wall in bowl or bell shape, and a suction unit. The apparatus for grinding biological samples contained in tubes (12), comprises a plate (10) for supporting the tubes, a unit for forcing the plate in oscillatory motion around a center of rotation located on an axis of the plate, a unit for cooling the tubes are carried by a part of the apparatus and surround the plate for defining a cooling zone having the tube oscillation zone carried by the plate, an air evacuation canal, a fitting type automatic multiple clamp, and an annular hood. The cooling unit (30) comprises an annular wall in bowl or bell shape, and a suction unit for heated gas present in an interior of the cooling unit, where the bell has double wall of which an internal wall having perforations for exiting cool air. A positioning or fixing unit (34) is placed on a fixed or movable part of the apparatus. The annular wall has a temperature lower than that of the tubes e.g. below 0[deg] C, and is intended for absorbing heat released from the tubes. The annular wall comprises a unit for introducing or circulating cool fluid equipped with nozzles for ejecting cool gas on the tubes, and a thermoelectric cooling unit. The cooling unit is placed on the fixed part of the apparatus, and is fixed with an interior of a flip cover. The air evacuation canal is formed in an upper-central part of the flip cover. The fitting type automatic multiple clamps is intended for carrying the tubes disposed in a housing equipped on the plate, where the carried tubes are automatically connected by elastic locking. The annular hood is equipped with elastic locking means. A control unit is formed by a push-button, and is mounted on the hood.</p> |
