Thermo Scientific* GENESYS 30 Visible Spectrophotometer Standards - Each

Check the performance and accuracy of your spectrophotometer right in your own laboratory using the Thermo Scientific SPECTRONIC Standards. This kit is as easy to use as a standard cuvette and contains:
• Calibrated neutral density glass standards for checking photometric accuracy at nominal values of 0.3A, 0.5A, 1A and 1.5A
• Calibrated standard for checking wavelength accuracy at nominal wavelengths on 400 nm, 522 nm and 777 nm
• Filter for checking stray light in UV-Vis instruments at 220 nm
• Filter for checking stray light in Vis instruments at 400 nm.

Set of 7 glass pieces mounted in metal frames sized to fit standard square cuvette holders.
Specifications
• Four calibrated neutral density glass standards for checking photometric accuracy at nominal values of 0.3A, 0.5A, 1A and 1.5A
• Standards are calibrated at 440.0n, 465.0 nm, 546.1 nm, 590.0 nm and 635.0 nm
• One calibrated standard for checking wavelength accuracy at nominal wavelengths on 400 nm, 522 nm and 777 nm
• The symmetry of the peaks means that tests of wavelength accuracy are independent of the spectral bandwidth (between 1 nm and 10 nm) of the instrument being tested
• 1 filter for checking stray light in UV-Vis instruments at 220 nm
• 1 filter for checking stray light in Vis instruments at 400 nm
• Each set of SPECTRONIC Standards is individually tested and certified to be accurate, with values traceable to the National Institute of Standards and Technology (NIST) or other Primary Standards
• Filters are supplied in a tough plastic storage container
• Recalibration service is available from Thermo Fisher Scientific. Recommended recalibration interval is two years
