Potassium Reference Cell

The Potassium reference spectroscopic cells are available in Pyrex or Quartz and come in range of sizes, styles, and window materials. Please enquire with your specific needs and we will have a spectroscopic cell for you at a reasonable price.

Double-side anti-reflective (AR) coated windows are only available on spectroscopic cells made from quartz, with quartz or fused silica windows.

Pyrex vapour reference cells are not available with wedged windows, but Pyrex windows can be attached at an angle.

The following cells are in stock and available for immediate delivery:
