The semi-demountable cell can be used either as a demountable cell or as a sealed cell for high-viscosity liquids or mull samples.

• Two rectangular cells in one demountable and sealed cell
• Easily disassembled for cleaning

The semi-demountable cell is ideal for samples that are hard to clean or for unknown liquids which may contain moisture and attack hygroscopic window materials. For mull samples liquid cells can also be used if sample is a Nujol™ mull or a capillary film, just use two undrilled windows and use the cell as a straight demountable cell.
