A blood cell counter manual is a type of laboratory equipment used to count and analyze blood cells. It is a manual instrument, meaning that it does not require electricity or any other type of power source to operate. Instead, it relies on the user to manually manipulate the instrument and perform the counting process.

Blood cell counters are used to determine the number of red blood cells, white blood cells, and platelets in a sample of blood. The results of these counts can be used to diagnose various medical conditions and monitor the progress of treatment.

Blood cell counters are commonly used in medical facilities, research laboratories, and other healthcare settings, and are an important tool for understanding the health and well-being of individuals.
