Four Port Variable Temperature Cuvette Holder

The Variable Temperature Cuvette Holder is a four-port version of the standard Variable Temperature Cell Holder, designed to accommodate quartz glass cuvettes of up to 10 mm pathlength. This cell holder is intended for liquid sample Raman, Fluorescence, and UV spectroscopic analysis. The four-port nature of the design means that collection of the (scattered) radiation can be at a 90° angle to the incident radiation as well as at a 180° angle as measured with a standard configuration. Specac’s Variable Temperature Cuvette Holder operates over temperatures from -190°C to 250°C. A pair of Spectrosil B (UV-grade fused silica) is provided as standard for two of the cell holder windows, and the other two window ports are fitted with blank (metal) windows. The cell holder is installed into an optical spectrometer sample compartment either via the 3″ x 2″ slide mounting plate, or with a Benchmark™ baseplate.
