¿ Use with General, Mammal, Erythrocyte, and Leukocyte Cell Counting¿ Dimensions: 25 x 75 x 1.6mm¿ Chamber Depth: 100um¿ Chambers per Chip: 2¿ Tests per Box: 100¿ Grid: Neubauer ImprovedDisposable plastic hemocytometer that improves upon the conventional glass variety. The C-Chip is the answer by offering the ability to eliminate tedious washing and reduce exposure to infectious samples and contamination. In a conventional glass hemocytometer, improper fitting of the chamber and cover slip changes the volume of the sample introduced into the chamber. The C-Chip all-in-one ¿chamber with an integrated cover¿ solves the problem. The C-Chip contains two precision engineered 100 ¿m height counting chambers that do not need cover slips. Just pipette 10¿l of sample into each chamber, place on the microscope and you are ready to count. Then dispose once finished.Packaged 50 slides (2 tests per slide) per box, individually sealed with a lot certificate in every box.
