What is cells Z DIMENSION(Zd)?
The Z dimension is the height from the bottom of the cell to the center of its sample chamber. In case of using a small volume cell in a spectrophotometer or fluorometer, the Z dimension of the cell should be the same as the height of the instrument’s light beam. The height of the light beam is usually 8.5 mm or 15mm, depending on the manufacturer. When ordering a cell which has more than one Z dimension available,it is necessary to specify the required Z dimension.
