(9B-Q-50) Semi-Micro Cell, Black Walled, Spectrosil, 50mm

The purpose of Semi­Micro Type 9 cells is to reduce the sample volume necessary to make a measurement. The volume of a Semi­Micro cell is approximately 40% of an equivalent path length standard rectangular cell. Semi­Micro cells are available with either clear walls parallel to the light beam or non transmitting self mask­ ing black walls which improve sensitivity by eliminat­ing stray light from measurements. The interior sample compartment width of Semi­Micro cells is reduced to 4mm, therefore it is essential to determine that the light beam from the instrument passes centrally through the sample compartment. This is especially important for long path length cells. Both the Type 9 and Type 9B are supplied with a PTFE cover (not pictured with the Type 9B or 9B9). Smaller sample volumes can be achieved by using cell Type 9/9 or 9B9 with a 9mm instead of a 3mm thick base. Note: Cells with a 9mm base are not suitable for an instrument with an 8.5mm 'Z' dimension.
