Liquid Sandwich Cells

Liquid Sandwich Cells
Sandwich cells provide for quick and easy installation within existing cell holders. A sandwich cell consists of a metal spacer assembled with one drilled and one undrilled window of the same material and dimension. Each sandwich cell offers leak-proof assembly with an amalgam seal. Standard pathlengths are 0.015mm, 0.025mm, 0.05mm, 0.10mm, 0.20mm, 0.50mm and 1.0mm.

Our most popular sandwich cells are assembled with 38.5 x 19.5 x 4mm windows. This series is available to fit sealed and demountable Perkin-Elmer style cells. When ordering, specify the spacer type for either a 14mm FTIR circular aperture or 10 x 22mm Dispersive rectangular aperture cell.

The transmission materials available for sandwich cell assemblies include but are not limited to NaCl Sodium Chloride, KBr Potassium Bromide, CaF2 Calcium Fluoride, BaF2 Barium Fluoride, KRS-5 Thallium Bromide Iodide and ZnSe Zinc Selenide.
