Sealed Liquid Spectrophotometer Cells - SL-4P Purgeable Heavy Duty

Our NAC-214 cell is available in both demountable and sealed spectrophotometer cell configurations that are purgeable while the cell is in the instrument, by using a Constant Purge bellows attachment. Unlike conventional sealed spectrophotometer cells which have luer fittings on the front plate, the purgeable SL-4P has luer lock filling ports that are mounted on the top and side edge of the 1/4 inch thick front plate of the cell. This construction allows the optical path of the spectrophotometer to be purged with nitrogen while it is in the sample compartment of the instrument, as the placement of the luer fittings facilitates the clean interface of a telescopic purge chamber to the front plate.
