Sahli's haemocytometer is a laboratory device used to estimate hemoglobin concentration in blood. It includes a graduated glass tube, a comparator, and a pipette for accurate measurement. The blood is mixed with hydrochloric acid, allowing hemoglobin to convert into acid hematin. The resulting color is then compared with standard shades to determine hemoglobin levels.

A haemocytometer is a specialized counting chamber used to count blood cells or microorganisms under a microscope. It consists of a thick glass slide with a grid etched into its surface. Micropipettes are used to accurately measure and load small volumes of liquid samples onto the haemocytometer. Together, they help in obtaining precise cell counts in medical and research laboratories.
