HBG Neubauer-improved with bright lines
Neubauer-improved
The Neubauer-improved counting chamber has become the most popular one.
Its standard depth is 0.1 mm. The grid consists of 3 x 3 large squares with
areas of 1 mm² each. The large square in the center is subdivided into
5 x 5 group squares with edges of 0.2 mm length each. These group squares
are again subdivided into sixteen small squares of an area of each 0.05 mm
x 0.05 mm = 0.0025 mm².
The lines limiting the large squares and the group squares are threefold with
the central line as the actual dimension lines. The inner and outer auxiliary lines
facilitate counting. They assist determining whether cells near or on the border
lines are to be counted as within the area or omitted as outside of the
counting area.
As the counting chamber comes with squares of different sizes it can be
used for counting different types of cells. E.g. leucocytes are counted in the
4 large squares at the corners of the grid and for counting erythrocytes at least
5 group squares are normally used
Bright line:
The grids of counting chambers with bright lines are engraved into a thin,
vapour-deposited metal film. The bright lines contrast well with the darker,
metallic background which facilitates the evaluation.
