Cells & Windows

Sealed liquid cells are designed as a preassembled integral unit. These rectangular sealed cells are made of calcium fluoride, have a pathlength of 0.2 mm and are great for highly volatile samples and quantitative analysis.

These rectangular cell holders have a lightpath of 50 mm.

Zinc Selenide (Irtran-4^™)Irtran-4 is similar to Cleartran except that it is somewhat softer and more easily scratched. Irtran-4 is used in total reflectance accessories because of its high refractive index.

These calcium fluoride semi-demountable cells are preassembled and have a pathlength of 0.2 mm.

The Window Aligner from PerkinElmer is required for the assembly of semi-demountable cells for analysis of highly viscous liquids and mull samples.

windows, with covers.

These calcium fluoride semi-demountable cells are preassembled and have a pathlength of 1 mm.

PTFE spacers can be used for the analysis of less viscous samples.

The pluggable female coupling is used for cell thermostatting and fits all Polarimeters.

The Quick Release Nut available from PerkinElmer is a part required for the assembly of the Semi-Demountable Cell.

Sodium Chloride (NaCl) Semi-Demountable Cell Windows from PerkinElmer are extremely versatile due to their spectral range and low cost.

Sealed liquid cells are designed as a preassembled integral unit. These rectangular sealed cells are made of sodium chloride, have a pathlength of 0.2 mm and are great for highly volatile samples and quantitative analysis.

Sealed liquid cells are designed as a preassembled integral unit. These rectangular sealed cells are made of sodium chloride, have a pathlength of 0.5 mm and are great for highly volatile samples and quantitative analysis.

Cesium Iodide Semi-Demountable Cell Windows have an extended spectral range and are used for analysis of high viscosity liquids and of mull samples.  

Sealed liquid cells are designed as a preassembled integral unit. These rectangular sealed cells are made of potassium bromide, have a pathlength of 0.05 mm and are great for highly volatile samples and quantitative analysis.

Potassium Bromide(KBr) KBr has a slightly wider spectral range than NaCl but is more hygroscopic. Although able to provide good resistance to mechanical shock, KBr is easily cleaved. KBr can be used up to 300 °C.

High efficiency. Thermostattable. No birefringence effects. Easy to fill, easy to empty, with no loss of sample. Fits all our Polarimeters (Models 141, 241, 241 MC, 243, 341, and 343).

PTFE spacers can be used for the analysis of less viscous samples.

OilExpress Flow Cell Windows made from Zelenium Selenide are available from PerkinElmer for analysis of oil samples using infrared sampling optics. Fitted to ensure moisture resistance.

The flow cell glass polarimeter cell has a 5 mL volume capacity, 100 mm lightpath, and is highly efficient, thermostattable, and has no birefringence effects. It is easy to fill and empty with no loss of sample.

Sealed liquid cells are designed as a preassembled integral unit. These rectangular sealed cells are made of calcium fluoride, have a pathlength of 0.025 mm and are great for highly volatile samples and quantitative analysis.

We carry Teflon Plugs for Semi-Demountable Cells which are used to analyze mulls or high viscosity liquid by FT-IR.

The Cylindrical Cell Holder accommodates cylindrical cells with path lengths up to 100 mm.

Silver Bromide (AgBr) - AgBr is easily scratched and has a tendency to cold flow at room temperature.

PTFE spacers can be used for the analysis of less viscous samples.
