Genrui 3 part differential hematology analyzer uses Coulter’s Principle and is able to differentiate between 3 types of WBC’s, neutrophils, lymphocytes, and monocytes. In a 3 part hematology analyzer basophils and eosinophils cannot be differentiated and are grouped with a population of either neutrophils or monocytes. 

Genrui also has a 5 diff hematology analyzer coping with different testing requirements.
