This calibration set consists of eight liquid filters which enable the complete checking of the spectrophotometer according to European Pharmacopeia. They are designed for use with the standard 10 mm cell holder provided with spectrophotometers. The set is supplied in a sturdy wooden case. For identification purposes a number is engraved on each filter. The absorbance values and/or peak position wavelengths of every filter are quoted in the accompanying calibration certificate.
