This PerkinElmer B250-0100 Secondary Standard Set Pharmacopoeia (UV Standard) is in excellent used condition. The kit is complete with all six sealed solution cells and original documentation intact.

The kit verifies all four critical spectrometer performance parameters in accordance with DAB, USP, and EP Pharmacopoeia monographs:
• Potassium Dichromate — photometric (ordinate) accuracy
• Holmium Perchlorate — wavelength (abscissa) accuracy
• Potassium Chloride / H2O — stray radiation level
• Toluene in Hexane — instrument resolution

The kit includes:
• 2 x sealed aluminium UV-protective containers (each housing cells)
• 6 x sealed 10 mm path-length solution cells (4 test + 2 reference)
• Certificates of Calibration issued 26 October 2020 by PerkinElmer LAS, Inc., traceable to NIST/NBS/PTB reference materials
• Hellma Analytics safety information documentation
• Hard protective carry case

Please note: the original calibration certificates are dated October 2020. Buyers in regulated environments should consider recertification before use in a live compliance workflow. The cells and hardware are in excellent physical condition.

The PerkinElmer B250-0100 Secondary Standard Set Pharmacopoeia (UV Standard) is designed to verify the calibration performance of UV/Vis and UV/Vis/NIR spectrometers in full accordance with DAB, USP, and EP Pharmacopoeia monographs. It is the standard solution kit for regulated laboratory qualification, OQ, and compliance auditing.

The set comprises six solutions in sealed cells — two reference solutions and four test solutions — covering every key instrument performance parameter required by international pharmacopoeial standards. The cells are designed for use with the standard 10 mm cuvette holders of most UV/Vis and UV/Vis/NIR spectrometers, making the kit broadly compatible across the LAMBDA instrument range and other manufacturers' instruments.

Key highlights:
- Four test solutions covering photometric accuracy (potassium dichromate), wavelength accuracy (holmium perchlorate), stray radiation (potassium chloride), and resolution (toluene in hexane)
- Two reference solutions: 0.001 N perchloric acid and water
- Calibrated in a PerkinElmer ISO/IEC 17025-accredited reference laboratory
- Traceable to NIST, NBS, and PTB primary reference standard materials
- Supplied in re-usable UV-protective aluminium storage containers
- Certificates of Calibration included
- Periodic recertification available from PerkinElmer
