An evaluation of the Vickers Instruments J12 cell counter

摘要

The Vickers J12 cell counter uses an optical hydraulic counting system to perform rapid automatic counts of leucocytes and erythrocytes in liquid suspension. The effect of sample storage, the use of different diluents, variation in cell dimensions and other relevant factors have been studied. A counting accuracy of ± 1·19% for replicate erythrocyte counts and ± 2·94% for leucocyte counts was obtained.
