APPARECCHIATURA PERFEZIONATA PER ESEGUIRE DETERMINAZIONI MULTIPLE DI VELOCITA' DI ERITROSEDIMENTAZIONE SU SANGUE UMANO, ANIMALE O SU ALTRI LIQUIDI

The object of this invention is an apparatus for carrying out multiple tests of erythrosedimentation speed on blood or other liquids comprising a series of pipettes (5) communicating with a single cavity under depression, a means for the zero setting of the samples in the pipettes at the higher level, a closing means for the lower end of the pipettes, a means for reading the values capable of signalling the transparency of the liquid contained in the pipettes; in such apparatus the means of automatic simultaneous zero setting of the samples is formed by a valve (9, 11), placed at the zero level of each pipette (5). A suction pump is connected with the chamber (2a) to which the pipettes (5) are attached, so that it can at first discharge the samples, collecting them in a trap bottle, and then sucking a washing liquid placed under the pipettes (5).
