Our SL-4 cell is now available in both demountable and sealed cell configurations that are purgeable while the cell is in the instrument, by using a Constant Purge™ bellows attachment (0005-7404). Unlike conventional sealed 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' 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.
