COD Reflux Digestion System YP-6, 6 Samples (CAT#: STEM-AL-9056-ZJF)

The YP-6 is a COD reflux digestion system intended for chemical oxygen demand reflux digestion of water samples. It is designed to heat multiple water samples under controlled reflux conditions before COD determination. The optical, thermal, or analytical configuration uses a six-position heating system for 250 mL Erlenmeyer flasks with air-cooled reflux tubes. Operation is supported by microprocessor-based timed heating control and controlled boiling digestion. The instrument provides the measurement modes and data handling functions stated in the source. It can be integrated into laboratory COD sample preparation. The stated performance and operating limits are restricted to the source-provided specifications. Overall, the system provides a six-position reflux digestion platform for COD analysis.
