Thermo Scientific™ SPECTRONIC™ Spectrophotometer Standards

Description

• 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 400nm, 522nm and 777nm Filter for checking stray light in UV-Vis instruments at 220nm Filter for checking stray light in Vis instruments at 400nm Set of 7 glass pieces mounted in metal frames sized to fit standard square cuvette holders
• 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, 465.0nm, 546.1nm, 590.0nm and 635.0nm One calibrated standard for checking wavelength accuracy at nominal wavelengths on 400nm, 522nm and 777nm The symmetry of the peaks means that tests of wavelength accuracy are independent of the spectral bandwidth (between 1nm and 10nm) of the instrument being tested 1 filter for checking stray light in UV-Vis instruments at 220nm 1 filter for checking stray light in Vis instruments at 400nm 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 Note: Stray light filters should block light completely at the measurement wavelength and are therefore not something that can be calibrated.
