ROCKER COD Reactor model CR25 179250-22

CR 25 (179250-22) is a chemical oxygen demand (COD) thermoreactor designed to perform closed-reflux COD digestion for water and wastewater testing. The unit accepts a 25-position heating block for 16 mm COD vials and provides programmable heating profiles, countdown timer and audible alarm for standardized COD methods (ISO 15705:2002) and related analyses. The reactor includes temperature control and over-temperature protection for safe, repeatable digestion of environmental and industrial water samples.

Key Features:

• Model/Part: CR 25, 179250-22 (AC 220V, 50Hz)
• 25-position heating block for 16 mm COD vials
• Temperature range: ambient +5°C to 200°C; accuracy ±2°C; stability ±1°C
• Built-in programs (examples): COD 150°C/120 min, COD2 165°C/20 min; two user-definable programs; timer 1–999 min
• Display: OLED; Maximum power: 350 W; Overheat auto-shutoff at >220°C
• Certifications: CE and UKCA; ISO 15705:2002 compliance for COD testing

Advantages:

• Programmable presets and user-definable programs enable standardized and repeatable COD digestion workflows.
• 25-position 16 mm block increases throughput for routine environmental and wastewater laboratories.
• Integrated safety features (anti-heat PTFE plate, over-temperature auto-shutoff and optional protective lid) reduce operator exposure to high temperatures and vial failures.
