  • Demountable Liquid Cell

    The Spectral Systems Demountable Liquid Cell is an ideal accessory for the analysis of liquids when a wide range of component concentrations is encountered and when the sample type varies frequently. The pathlength of the analysis is defined by your choice of spacer included with the accessory. Spacers are composed of Teflon® which is inert and compatible with all sample types. Spectral Systems offers a complete selection of window materials for analysis in the mid-, near- and far-infrared spectral regions and to provide compatibility with organic and aqueous solvents. All windows offered for our Demountable Liquid Cell are edge rounded and finished for exceptional durability and improved seal.
