Cuvette carriage for a 2 mm path rectangular cell
This cuvette carriage holds a 10 x 2 mm cuvette (12.5 x 4.5 mm outside dimensions) in the CD 250 cuvette holder. After placing the carriage in the CD 250, captured tie-down screws allow the user to screw the holder in position to make good thermal contact with the temperature-controlled base. The incident spectrometer beam passes through the 2-mm dimension of the cuvette at a z-height of 15 mm. When properly bathed in nitrogen flow, the cuvette is held in an environment free of oxygen and moisture.
