DEVICE FOR THE REFRIGERATED STORAGE AND DELIVERY OF SAMPLES AND AN INTEGRATED LIQUID COOLING UNIT THAT IS SUITABLE THEREFOR

摘要

The invention relates to a device for the refrigerated storage and dispensing of substance samples, in particular a sample dispenser that is used in chromatography. Said device comprises a holder (7) for receiving one or more substance samples (3), at least one section of the holder (7) comprising at least one cavity (13) that is traversed by a liquid coolant (29), said cavity or cavities (13) being connected to a feed connection for supplying the coolant (29) and a return connection for evacuating the coolant (29). The device also comprises a liquid refrigeration unit (21), the feed connection of which is connected to the feed connection of the cavity or cavities (13) and the return connection of which is connected to the return connection of the cavity or cavities (13), a pump (23) for transporting the coolant (29) through the cavity or cavities (13) and a Peltier refrigeration unit (27) for cooling the coolant (29). In addition, the invention relates to an integrated liquid refrigeration unit (21) for a device of this type.
