STAN-ABS absorbance standards are handy tools for verifying the photometric accuracy of your spectrometer setup. The STAN-ABS-UV is good for the range from 200-450 nm. Each kit comprises a background reference for low, medium and high absorbance solutions and is ready to use without additional solutions preparation. All standards are non-toxic and have a one-year shelf life.


  • NIST-traceable – ensure accuracy in absorbance measurements at specified wavelengths
  • UV kit – for 200-450 nm wavelength ranges
  • Ready to use – no dilution or solutions preparation necessary
