Disposable IR cards have simplified sample preparation for infrared spectrometry. Moreover, they allow samples to be preserved for long periods, so that results can be verified at a later time. The Disposable IR cards contain a circular aperture, either of NaCl, KBR, or KCl. Inexpensive and disposable, they perform like traditional salt plates and are ideal for liquids, mulls, casting films from solutions, and pyrolysis samples.

These cards provide a conveniently mounted, non-absorbing substrate for qualitative infrared analysis. These substrates are impervious to atmospheric moisture. Optional square crystal cover slips may be used with 19 mm aperture cards to sandwich sample between window in sample card and cover slip for mulls and liquid samples.

  • NaCl, KBr, or KCl windows
  • Three apertures: 9.5, 15, and 19 mm
  • Transmission: 80+% for 15 and 19 mm, 70+% for 9.5 mm apertures
