Description

ICL's new RoHS compliant Model SL-15 sealed liquid cell (patent pending) employs a dynamic o-ring sealing system employing fluoropolymer seals that enable us to produce precisely calibrated cells that completely eliminate mercury and lead amalgam seals from the fabrication process. These cells are fully compliant with RoHS Directive 2011/65/EU. The SL-15 can be employed in any general lab application as stand-alone accessories or key components of a complete system. The SL-15 cell is so robust that it is also suitablefor high internal pressure environments such as flow cells used for viscous samples like oil. Where there are internal cell pressures as high as 40 psi, cells with suitable windows will remain leak free and maintain their path length integrity with long service life. The configuration of the cell optics using o-rings as seals, does not rely on the spacer itself to be a sealing element; therefore the amalgams and other undesirable adhesives and materials including mercury and lead have been eliminated. The seal configuration also permits innovative cell configurations for UV/VIS spectroscopy and Raman which usually employ cuvettes comprised of glass or fused silica. The innovative sealing scheme is made possible by the DuroStepTM design and features O-Ring-OnlyTM seals which are exclusive to the SL-15 cell from ICL. Cells can be provided at a wide range of pathlengths: 0.025mm, 0.05mm, 0.1mm 0.2mm, 0.5mm and 1mm pathlengths are all available. Any window can be used, the most common being BaF2, CaF2, KBr, ZnSe, and IR Quartz. Various types of o-rings can be used, most commonly Viton is provided, but also Kal Rez is available for extreme chemical compatibility. Cells come with a variety of sample fitting configurations as well. For high vacuum or high pressure performance, Swagelok TM brand fluid connections are provided. Other common connections like Luer-Lock and Beswick hose connections are also available.
