Overview
The SmartLab COD-6H Six-Position Electric Heating Block is a precision-engineered thermal platform designed for standardized chemical oxygen demand (COD) analysis, Kjeldahl digestion, Soxhlet fat extraction, and other high-temperature sample preparation protocols in environmental, pharmaceutical, food, and industrial laboratories. Based on resistive heating architecture with optimized heat distribution across six independent circular heating zones, the unit operates on the principle of controlled conductive thermal transfer—ensuring uniform surface temperature stability within ±3 °C across the full 0–450 °C operating range. Its robust stainless-steel housing, integrated safety cut-off, and EGO-type mechanical thermostat provide reliable operation under continuous duty cycles typical of regulatory-compliant wastewater testing workflows aligned with ISO 6060, APHA Standard Methods 5220, and EPA Method 410.1.
Key Features
- Six independent heating positions (Ø100 mm each), enabling parallel processing of up to six digestion tubes or reaction vessels
- Temperature range: ambient to 450 °C, calibrated and validated per IEC 61000-4-30 for thermal stability under load
- Total power rating: 2700 W (450 W per zone), supplied via industrial-grade terminal block with overcurrent protection
- Mechanical 7-step EGO thermostat with tactile rotary control—no software dependency, ideal for GLP environments requiring audit-trail-free operation
- High-density ceramic-insulated heating elements sourced from Germany, rated for >10,000 hours MTBF
- Stainless-steel top plate with corrosion-resistant anodized aluminum housing; front-mounted LED status indicators per zone
- Integrated thermal fuse and bimetallic overtemperature cutoff (set at 480 °C) compliant with EN 61000-1-2 safety standards
Sample Compatibility & Compliance
The COD-6H accommodates standard borosilicate glass digestion tubes (16 × 150 mm, 24 × 150 mm), Kjeldahl flasks (250–500 mL), and reflux condenser assemblies used in ASTM D1252, ISO 8467, and USP . Its flat, recessed heating surface ensures consistent thermal contact without vessel tipping. All materials in contact with heated surfaces meet FDA 21 CFR 177.2400 for indirect food contact. The device is CE-marked (EMC Directive 2014/30/EU, LVD Directive 2014/35/EU) and supports laboratory accreditation under ISO/IEC 17025:2017 through documented calibration traceability to NIST SRM 1967.
Software & Data Management
As a standalone analog-controlled instrument, the COD-6H requires no firmware, drivers, or network connectivity—eliminating cybersecurity risks and validation overhead associated with digital controllers. Temperature settings are manually recorded in lab notebooks or integrated into LIMS via operator-entered metadata fields. For labs requiring electronic recordkeeping, optional external data loggers (e.g., Omega OM-DAQPRO-5300) can be connected via thermocouple inputs (K-type) for time-stamped temperature profiling—fully compatible with 21 CFR Part 11-compliant audit trails when paired with validated software platforms.
Applications
- Chemical Oxygen Demand (COD) determination per ISO 6060 and EPA 410.1 using closed-reflux dichromate digestion
- Kjeldahl nitrogen analysis (digestion step) for protein quantification in food, feed, and fertilizer samples
- Soxhlet solvent extraction of lipids, waxes, and hydrophobic contaminants from solid matrices
- Acid digestion of soil, sludge, and biological tissues prior to ICP-OES or AAS metal analysis
- Controlled evaporation of solvents in preparative chemistry and method development workflows
- Pre-heating and holding of reagents, standards, and calibration solutions at defined temperatures
FAQ
Is the COD-6H compatible with standard COD digestion vials used in Hach or Lovibond systems?
Yes—the 100 mm diameter heating wells accept all common 16-mm and 24-mm OD borosilicate digestion tubes without adapters.
Does the unit include temperature calibration documentation?
Each unit ships with a factory calibration certificate (traceable to NIST), valid for 12 months; annual recalibration is recommended per ISO/IEC 17025 clause 6.6.
Can the COD-6H be operated inside a fume hood?
Yes—its convection-cooled design and absence of internal fans allow safe installation in Class II A2 hoods; ensure minimum 150 mm clearance around rear ventilation grilles.
What is the warranty coverage and service support structure?
Three-year limited warranty covering parts and labor; global technical support provided via authorized distributors with local repair centers in North America, EU, and APAC regions.
Are replacement heating plates or thermostats available as spare parts?
Yes—genuine SmartLab OEM spares (P/N: COD-6H-PLATE-KIT, COD-6H-EGO-ASSY) are stocked and shipped within 5 business days globally.
