View resource →Product overview
AF332 provides visual pharmaceutical-solution grading to European Pharmacopoeia 2.2.2 with five stable glass discs covering the R, Y, B, BY and GY ranges.
Key features
- An integrated prism brings the sample and comparison fields together for colour discrimination; ultrasonic sealing protects the optics.
- Calibrated glass standards represent discrete, colour-stable grades for direct sample matching.
- Five discs cover the R, Y, B, BY and GY series; 40 mm cells graduated at 20 ml support pharmacopoeial colour comparison at the specified path length.
- The supplied Daylight unit provides consistent illumination and reduces the influence of changes in ambient lighting.
