Abstract
Apparatus for the analysis of samples such as blood or urine includes a reaction cell for reacting the sample with a chemical reagent at a predetermined temperature. A heat exchanger is provided on the reaction cell for establishing the temperature of the cell. Reagent is pumped into the cell through a conduit, and a portion of the conduit is wound around the reaction cell in contact with the heat exchanger to preheat reagent in the conduit before the reagent is pumped into the cell.
