ABSTRACT:
An analysis system has a first region in which sample materials are stored at an appropriate storage temperature and an analysis region which is maintained at a controlled and stabilized temperature higher than the temperature of the first region. Transfer mechanism for transferring a quantity of sample material from the first region for loading into an analysis cuvette in the analysis region includes a liquid handling probe that is mounted on a probe transport carriage, and a drive for moving the transport carriage between the first and second regions. The transport carriage includes a storage chamber connected to the liquid handling probe, thermal energy supplying means in heat exchange relation with the storage chamber, and thermal sensor means carried by the transport carriage. Means responsive to the thermal sensor supplies thermal energy to the transport carriage to maintain the storage chamber at substantially the same temperature as the analysis region.
