Abstract

An apparatus for analyzing biological liquids comprises a measuring block including measuring means for measuring characteristics of said liquids. The measuring block is mounted within a thermal shield or housing by means of a base member interconnecting a minor part of the inner wall of the housing and the measuring block so as to define a space between the inner walls of the housing and the measuring block, said space being filled with air or another medium having a poor thermal conductivity. The thermal shield or housing and the base member are made of a material with good thermal conductivity, and heating and/or cooling means are arranged in heat conductive contact with the said shield. The function of the heating and/or cooling means is controlled by a temperature sensor arranged in heat conductive contact with the measuring block, so as to maintain the temperature of said block at a substantially constant predetermined value.
