The SL-2 is available in dispersive and FTIR configurations. The price of the cell in the sealed cell configuration includes both the mount and the sandwich cell that fits in the mount. Pathlengths can be nominal or calibrated to 4 decimal places (eg. 1.0152mm) and cell pathlengths can be matched within ±3% for interchangability. ICL also offers an infared cell reconditioning service and a calibration service for all spectrophotomer cells.
