  • Easily and accurately perform certified spectrophotometer evaluations in your own laboratory

  • Easily and accurately perform certifified spectrophotometer evaluations in your own laboratory
  • Standards are designed for use in visible light ranges
  • Standards are ISO17025 accredited for testing and calibration
Check the performance and accuracy of your spectrophotometer right in your own lab. Simply insert standards into your spectrophotometer's cell holder. Standards include:
0% transmittance: the opaque 0%T standard is used to test for light leaks in your spectrophotometer.
Wavelength 590 nm: the wavelength accuracy standard has a transmittance peak near 515 nm which is certified as a wavelength accuracy standard and is NIST traceable. The symmetry of the peak means that the tests of wavelength accuracy are independent of the spectral bandwidth (up to 20 nm) of the instrument being tested. In addition, the testing peak of 515 nm is located at that point when the tungsten lamp shows the flattest energy measurement in response to wavelength change.
Stray radiant energy: each of these three standards is essentially opaque at its test wavelength and highly transmitting at longer wavelengths. The test wavelength is chosen (220 nm, 340 nm, and 400 nm) to correspond to points of low energy for both tungsten and deuterium lamps, readily revealing any stray energy for both the visible and UV regions.
Photometric performance: these 10% T and 50% T neutral density filters test spectrophotometric accuracy, precision, and linearity. No spectral bandwidth is required. The control standard verifies that the holder itself does not affect the 100%T reading.
Optical alignment: optical alignment in the sample compartment can be evaluated by using the control standard and photosensitive paper. The paper records the position of the light beam in the cuvette holder.

    • Q:

      why there are two sets of 10% T and 50% T neutral density filters for photometric performance

        A:

        These 10%T and 50%T Neutral Density filters test spectrophotometric accuracy, precision and linearity. To test linearity there has to be more than one test point. Since the transmittance of this glass is extremely constant with changes in wavelength near 590 nm, spectrophotometric errors can be distinguished from wavelength errors. No spectral bandwidth compensation is required. The Control Standard verifies that the holder itself does not affect the 100%T reading.

    • Q:

      I am interested in getting these recertified. How can I do this.

        A:

        Recertification may be completed through the return and purchase of part number 00256IO.

    • Q:

      Does this come with a instruction manual? If so, how can I get one, since we already have the set?

        A:

        No, this product does not come with an instructional manual. There should be instructions for calibration in the manual for the meter.

    • Q:

      Can I purchase just one or a few standards, instead of the set?

    • Q:

      Can I use this for our 20-D Milton Roy Spectrophotometer
      Asked on 8/10/2009 by Nette from Philippines

      • A:

        Before purchasing ANY kit please check that tolerances of all measurements provided in the kit's certificate (so-called Expanded Uncertainties) are not too loose for adequate testing of performance of your spectrophotometer. Another words, higher quality spectrophotometer you have, better tolerances are required for calibration standards to test the spectrophotmeter adequately. The best calibration standards and kits are offered by NIST and by only few other companies in the world which manufacture NIST compliant and/or NIST compatible calibration standards and kits. ("NIST traceability" statement is used by many manufacturers of kits and standards but it is NOT the same as "NIST compliance"/"NIST compatibility"). Certainly, these standards are much more expensive comparably to the cost of this kit.

        A:

        These standards should work with most spectrophotometers, not just Thermo brand products.
