A. KRÜSS P9000 Series - Digital Polarimeters
Faster. Better. More Reliable.
The A. KRÜSS P9000 Series is the new generation of digital polarimeters designed for the most demanding pharmaceutical quality control and research environments. Combining integrated tempering, intelligent assistance systems, and full regulatory compliance, the P9000 Series sets a new benchmark for precision polarimetry.
Key highlights:
- Full regulatory compliance — firmware and data management are fully compliant with 21 CFR Part 11 and EU GMP Annex 11, with tamper-proof audit trail, signed PDF/A exports, and multi-level user management.
- Intelligent TempGate® system — integrated Peltier tempering ensures sample temperature accuracy to ±0.1 °C across the entire 15–45 °C range, eliminating measurement errors caused by thermal gradients.
- Sample Cell Check with integrated camera (P9200-P) — live visual inspection of the measurement cell during filling detects air bubbles, particles, and streaks before they affect results, with automatic documentation for quality records.
- 8 selectable LED wavelengths — from 365 nm to 880 nm, all generated by high-performance LEDs with a rated lifetime of over 100,000 hours; the standard 589 nm sodium D-line is always included, with additional wavelengths retrofittable at any time.
- RFID-enabled cuvettes & quartz control plates — automatic recognition of cell length, material, and tempering parameters, with PTB-certified quartz plates for traceable calibration, all guided through a clear on-device menu.
Technical specifications: Measurement range: ±90° / ±259 °Z · Accuracy (P9200-P): ±0.002° · Resolution: 0.001° · Measurement time: ~1 s · Min. sample volume: 1.3 ml · LED lifetime: >100,000 h
