Abstract

A method and an apparatus are disclosed for facilitating the testing of samples of liquids, for example biological liquids to be tested by photometric means. In order to prevent errors attributable to pollution caused by the previous sample being tested, provision is made for the liquid to be tested to flow along and to fill a path (10, 3, 9, 14) in which is disposed a chamber (3); then the column of liquid in the path (10, 3, 9, 14) is advanced until that portion previously in pipe (10) occupies chamber (3), whereupon the liquid portion in chamber (3) can be read. Valves (16, 22), preferably electromagnetic valves, are provided in suction lines (14, 20) for drawing liquid from a test- tube (P) containing the sample to the chamber (3). Gas streams can be used to dislodge possible residues of previous samples and/or washing liquids from the chamber (3), and to de-gasify the liquid in the chamber (3) before it is read. <IMAGE>
