Micro cells have the same outside dimension as Macro cells. Their cell walls have been thickened, limiting the interior sample chamber width to 2 mm. Each cell has a standard path length of 10 mm with black side walls and base. Each package contains two cells.
The Special Optical Glass, or SCHOTT type UK 5 glass, is made from exceptionally pure raw materials. An empty Special Optical Glass cell offers a transmission of more than 80% over a spectral range of 320 - 2,500 nm. These cells are identified by a green PerkinElmer logo.
