The Variable Pathlength Liquid Cell (VPLC) series permits continuous adjustment of sample pathlength from 0 - 6mm. The VPLC is preferred for liquids analysis without dilution and an excellent analytical tool for differential analysis. The cell's pathlength can be adjusted with precision to provide peak intensity for both weak and strong bands. The micrometer and venier scales provide for accurate pathlength setting and readability in graduated divisions of 0.0005mm. The cell volume at maximum pathlength is 4.5ml.
