  • Temperature regulation in a sample handling system for an optical monitoring system
    Patent number: 5236666
    Abstract: An arrangement is provided for temperature regulating a fluid sample in a cuvette transported through various stations of an automated system for optically monitoring the sample in the cuvette. A track guides the cuvette through the various stations of the optical monitoring system. The sample is in heat exchange relationship with the track by way of the cuvette. A drive unit drives the cuvette along the track. A cooling unit cools a first portion of the track. A heating unit heats a second portion. A heat flow restriction device restricts heat flow between the first and second portions of the track.
