Thomas Square Spectrophotometer Cell, 0.9mL Capacity, 334 to 2500nm Spectral Range

Micro cell are for use when available sample volume is less than the volume required for standard square cells. The nominal working volume of these cells is as little as 20 percent of that for standard cells of the same path length. Required volume of the Semi-Micro cells of 0.9mL can be reduced by elevating the cell so long as the light beam does not strike the walls of the cell. If beam width of spectrophotometer approaches 4 mm, a suitable self-masking cell should be used. With black self-masking walls and bottom plate which absorbs all direct and scattered light for improved sensitivity.
