The macro cell which is defined by DIN 58963 as a rectangular cell with an inner width greater than 5 mm has emerged as the standard for photometry. The most widely used macro cell is a rectangular cell with outer dimensions of 45 x 12.5 mm (height x width). The length of the cell is dependent on the desired path length.
Spacers are required for cells with an outer depth of less than 12.5 mm to hold them securely in the cell holder.
