Haemocytometer Neubauer improved - Bright line, Super grade

Haemocytometer (Cell Counting Chamber)

This Neubauer Improved bright line haemocytometer (also spelled hemocytometer, and also known as a cell counting chamber or microscope grid slide) is a tool used for manual cell counting. As the name implies, it was originally invented for quantifying blood cells. It is used for counting microscopic objects suspended in fluid, such as cells and platelets in diluted blood, or bacteria in culture.

There are several types of hemocytometers, all with different counting grids. The most commonly used is the Improved Neubauer chamber. The depth of the chamber is 0.1 mm.

What is the Improved Neubauer chamber?

The Improved Neubauer has an H-shaped indent at the centre of the slide that separates the space into two counting chambers. Grids are engraved onto the surface to make cell counting easier and more precise.

The 3 x 3 mm counting grid is subdivided into nine 1 x 1mm squares. Each square is further divided into 16, 100 or 400 smaller squares, and the various grids allow you to count cells of different sizes. An area subdivided into 25 smaller squares (1/25 mm²) has each of them surrounded by triple lines and then further divided into 16 (1/400 mm²).
