larger image	For KBr Pellet & Polymer Film Sample ICL's popular Econo Cards are an ideal vehicle for mounting KBr pellets and polymer films or for use with disposable polyethylene IR transmission windows. They are available with 19mm and 9.5mm circular apertures. Econo Cards have a pressure sensitive adhesive on the inside surface, but the adhesive is kept away from the aperture and outside of the path of the spectrophotometer beam to avoid spurious absorbance peaks. The sample is mounted on the adhesive surface and the cards then folds over into a 2" x 4" card that can be inserted in the slide mount in any spectrophotometer or used to store the sample for future reference.
