Analyzing Liquid Streams with Basic Liquid Transmission Flow Cells

The Durasens™ LT-B Series Liquid Transmission Flow Cells are ideal for examining liquid streams using transmission spectroscopy. These are reliable, field-tested basic cells. The flow cells have a sturdy 316 stainless steel construction and are provided with a wide range of window materials and pathlengths which make these cells equally at home in the pilot plant, laboratory, or manufacturing plant.

The pathlength can be easily altered by changing the spacer. The demountable design makes it easy to disassemble the cells for cleaning, or for the exchange of pathlength spacers and windows.

The LT-B Series cells are provided with round clear apertures of 20 mm (Model LT-B25) and 8 mm (Model LT-B13). The two models are available in temperature-controlled versions (Models LT-B13-T and LT-B25-T). The temperature-controlled versions are thermally insulated cells having low-voltage cartridge heaters, an embedded K-type thermocouple, and a flow-through cooling conduit.
