Product Description

Our NAC-213 and purgeable NAC-214 sealed liquid cells have been modified for flow applications that apply much higher pressures to the seals and windows of the cell than would be applied to a sealed liquid cell under normal filling conditions. These cells are available with all window materials on request, but we recommend using ZnSe and ZnS with 0.1mm pathlengths. The cells are reinforced with high strength seals which are external to the sample cavity and will not cause contamination. Both the ZnSe and ZnS NAC-213 cells are rated for 35 psi with a pathlength of 0.1mm while the NAC-214 is rated for 60 psi. Before shipment, all cells are pretested for leaks at the rated pressure. Fringing is also calibrated within a limited fringe amplitude range that is sufficient to permit accurate cell calibrations while minimizing interference with analysis. Tubing connections can be demountable or permanent.

The luer lock version (on the right), is demountable and employs our standard conversion kit to add the flow cell connections to the cell's standard luer lock filling ports. The conversion kit comprises a male luer lock assembly and a compression fitting with a Delrin nut and a Tefzel ferrule which clamps the tubing in place. Using these adapters gives the cell the versatility to be used both as a flow cell and as a sealed cell to be filled by normal means with a luer lock syringe and facilitates easy removal and attachment of tubing by simply twisting the male luer lock connection onto or off of the female luer lock filling port on the cell. The luer lock version can be used with both 1/16” OD and 1/8”OD tubing. The permanent flow connection version uses brass fittings with small hose barbs which attach to 3/32” ID tubing, and is designed for applications where it will be used only as a flow cell. The purgeable NAC-214HPF is available only with demountable luer lock tubing connection adapters.
