Versatile Digestion Reactor for COD, TOC, Phosphate, Nitrogen, and Chromium Analysis
The Lovibond® RD125 Thermoreactor is a flexible, benchtop digestion unit designed for sample preparation prior to photometric analysis of COD, total nitrogen, total phosphate, total chromium, and TOC. Featuring a 24-slot heating block for 16 mm round cuvettes, three selectable temperature settings, and three pre-programmed reaction times, the RD125 simplifies digestion workflows in environmental and water quality laboratories.
Key Features
- 3 Temperature Settings: 100 °C, 120 °C, and 150 °C to suit different digestion methods
- Programmable Timer: Select from 30, 60, or 120 minutes (plus continuous mode)
- Automatic Shutdown: Unit powers off after digestion cycle completes
- 24 Sample Capacity: Holds up to 24 cuvettes (16 mm round)
- Voltage Selector Switch: Compatible with both 110 V and 220 V power sources
- Corrosion-Resistant Design: Epoxy-coated housing for long-term lab durability
- Audible Beeper: Notifies user when digestion cycle is complete
Applications
- COD (Chemical Oxygen Demand) – Low to high range testing (VLR to HR)
- TOC (Total Organic Carbon) – Environmental and industrial sample analysis
- Total Phosphate – Drinking water, effluent, and surface water evaluation
- Total Nitrogen – Comprehensive nitrogen monitoring (LR to HR)
- Total Chromium – Trace and high-level chromium analysis
