This suction pump assembly is dedicated to 3-Part differential hematology analyzer, long travel, high accuracy, long life and maintenance-free. The specifications of the three-channel plunger are different, taking into account the suction and drainage for micro volumetric sample, diluent and hemolytic agent . Cavity is moulded, low cost, good consistency. It is mainly used in 3-Part differential hematology analyzer, in which the empty travel interval of sampling pump body can effectively avoid the sampling abnormal movement caused by linkage, improve sampling accuracy and reduce control complexity.
