A tool used to count the number of blood cells in a specific amount of blood.
The scientist used a hemocytometer to determine the concentration of red blood cells in the sample.
Hemocytometer → It is formed from "hemo-" (from Greek "haima", meaning blood) and "cytometer" (from "cyto-" meaning cell and "metron" meaning measure). The word refers to an instrument used to measure the number of cells in a blood sample.
Think of 'blood' ('hemo-') and 'measuring cells' ('cytometer') to remember that a hemocytometer is used to count blood cells.
