The HeatIR™ Sampling Accessory provides a solution for temperature controlled infrared studies of liquid, mull or thin film samples. The accessory mounts conveniently into the slide sample holder of your FT-IR and is compatible with standard 32 x 3 mm infrared windows for demountable liquid cells. Liquid samples are loaded via fill ports on the needle plate of the cell. Solids can be measured by means of a mull and pressed between the cell windows. Film samples can be mounted within the heated cell using appropriate gaskets and compensating ring.
