Overview
The CZGY DB Series Digital Stainless Steel Electric Heating Plate is a precision-engineered laboratory heating platform designed for consistent, controllable thermal treatment of samples during sample preparation, digestion, evaporation, drying, and pre-heating protocols. Utilizing resistive heating elements embedded beneath a seamless 304 stainless steel top plate, the device delivers uniform surface temperature distribution across its active area—critical for reproducible results in analytical workflows. Unlike open-coil hotplates or ceramic variants, the solid stainless steel surface resists chemical corrosion from acids, bases, and organic solvents commonly used in wet digestion (e.g., HNO₃/HCl/HF mixtures) and environmental sample processing. Its analog-free digital PID temperature controller ensures stable setpoint maintenance within ±1 °C over the full operating range (ambient to 300 °C), meeting baseline thermal stability requirements for ISO/IEC 17025-compliant laboratories performing method-defined heating steps.
Key Features
- Corrosion-resistant 304 stainless steel working surface—mechanically durable and compatible with aggressive reagents used in EPA Method 3050B, 3051A, and ASTM D5681 digestion procedures.
- Digital LED display with intuitive push-button interface (SET, △, ▽) for precise temperature setpoint entry and real-time monitoring.
- PID-based closed-loop temperature control system—minimizes overshoot and stabilizes surface temperature within ≤2 minutes after setpoint change.
- Three standard configurations optimized for throughput and spatial demand: DB-1A (200 × 150 mm, 500 W), DB-2A (350 × 200 mm, 1000 W), DB-3A (400 × 300 mm, 1500 W).
- Integrated sensor error compensation function (SC parameter)—allows field calibration adjustment between −50 and +50 digital units to align displayed temperature with traceable reference thermometry (e.g., NIST-traceable RTD or thermocouple probe).
- Thermal cut-off protection and overtemperature safeguard circuitry—complies with IEC 61010-1 safety requirements for laboratory electrical equipment.
Sample Compatibility & Compliance
The DB Series accommodates a wide range of container types—including borosilicate glass beakers, quartz crucibles, PTFE digestion vessels, and ceramic evaporating dishes—without risk of surface adhesion or thermal shock-induced cracking. Its flat, non-porous surface enables easy cleaning and prevents residue accumulation that could compromise subsequent analyses. The unit is suitable for use in GLP-regulated environments where documented thermal consistency is required; while not inherently 21 CFR Part 11 compliant, its digital setpoint logging capability (when paired with external data acquisition systems) supports audit-ready recordkeeping. It meets general safety standards outlined in EN 61010-1 and is routinely deployed in labs adhering to ISO 17025 accreditation criteria for method validation involving controlled heating steps.
Software & Data Management
The DB Series operates as a standalone analog-digital hybrid instrument with no embedded firmware or network connectivity. Temperature setpoints and real-time readings are displayed locally via a 4-digit LED screen. For integration into LIMS or ELN ecosystems, optional external USB or RS-232 data loggers (sold separately) may be connected to capture time-stamped temperature profiles. Sensor offset correction (SC parameter) provides basic traceability alignment—users are advised to validate accuracy annually using a calibrated reference thermometer per ISO/IEC 17025 clause 6.5.2. No proprietary software is required; configuration remains accessible via front-panel controls only.
Applications
- Acid digestion of soil, sediment, and biological tissues prior to ICP-OES or ICP-MS analysis.
- Controlled evaporation of solvent extracts in pesticide residue testing (AOAC 2007.01, EN 15662).
- Drying of filter papers and gravimetric precipitates in water quality testing (APHA 2540B, ISO 11923).
- Pre-heating of reagent solutions and calibration standards in clinical chemistry and pharmaceutical QC labs.
- Support heating for reflux assemblies and distillation setups where uniform base temperature is essential.
- Thermal conditioning of culture media components before autoclaving in microbiology workflows.
FAQ
Can this heating plate be used for open-vessel acid digestion?
Yes—its 304 stainless steel surface withstands exposure to nitric, hydrochloric, and hydrofluoric acids at temperatures up to 300 °C when used with appropriate fume hood ventilation and PPE.
Is the temperature reading traceable to national standards?
The unit supports user-initiated sensor offset correction (SC parameter); however, full traceability requires periodic verification using an accredited reference thermometer per ISO/IEC 17025.
Does it support programmable ramp-soak temperature profiles?
No—the DB Series offers only single-point setpoint control. For multi-step thermal protocols, external programmable controllers or compatible data loggers must be employed.
What safety certifications does it carry?
It conforms to IEC 61010-1:2010 for laboratory electrical equipment, including dielectric strength, leakage current, and thermal cutoff requirements.
Can custom surface dimensions or power ratings be manufactured?
Yes—CZGY accepts OEM/ODM requests for non-standard configurations; lead time and minimum order quantities apply.
