Thomas Square Spectrophotometer Cell, 0.7mL Capacity, 320-2500nm 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 (8491S04, T21, T22, S51 and S52) 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. Internal width: 2-4mm approximate. Flared at top to assist filling.
