Overview
The MKN DHP-80 Electric Constant Temperature Incubator is a precision-engineered benchtop incubation system designed for stable, uniform thermal environments essential in microbiological culture maintenance, cell propagation, enzyme activity studies, and long-term biological sample storage. It operates on resistive heating with external heater placement—eliminating direct thermal radiation onto samples—and employs natural convection airflow to ensure homogeneous temperature distribution throughout the chamber. The unit is calibrated to maintain setpoint stability within ±0.5 °C across its operational range (ambient +5 °C to 65 °C), making it suitable for applications requiring ISO/IEC 17025-compliant environmental conditioning, GLP-aligned microbiology workflows, and routine QC procedures in pharmaceutical, academic, and agricultural research laboratories.
Key Features
- Microprocessor-based digital temperature controller with LED display, offering setpoint resolution of 0.1 °C and real-time monitoring of chamber temperature.
- Dual-layer tempered glass observation door with silicone-sealed perimeter—minimizes thermal leakage while enabling non-intrusive visual inspection without compromising internal stability.
- Externally mounted heating elements positioned at the rear wall—prevents localized overheating, eliminates temperature overshoot during ramp-up, and safeguards heat-sensitive cultures and reagents.
- Stainless steel interior chamber (304 grade) with rounded corners and seamless welds—facilitates cleaning, resists corrosion from repeated disinfection cycles, and complies with ISO 14644-1 Class 8 cleanroom-compatible surface requirements.
- Adjustable stainless steel shelving (2 standard shelves included; optional third shelf available)—supports flexible load configuration and unrestricted air circulation.
- Over-temperature protection circuit with independent mechanical safety thermostat—automatically cuts power if internal temperature exceeds user-defined limit by >3 °C.
Sample Compatibility & Compliance
The DHP-80 accommodates standard Petri dishes (up to 150 mm), multi-well plates (6–96-well), test tubes (13–18 mm OD), Erlenmeyer flasks (up to 1000 mL), and sterile storage containers. Its chamber volume (80 L) and uniformity profile meet ASTM E171-22 requirements for thermal uniformity testing of laboratory ovens and incubators. The device conforms to IEC 61010-1:2010 for electrical safety in laboratory equipment and supports documentation traceability required under FDA 21 CFR Part 11 when integrated with validated data logging systems. It is routinely deployed in facilities adhering to USP , ISO 13485, and WHO TRS No. 961 Annex 2 for microbiological quality control environments.
Software & Data Management
While the DHP-80 operates as a standalone analog-digital hybrid unit, its RS-232 serial interface enables connection to external PC-based data acquisition platforms (e.g., LabVIEW, MATLAB, or custom Python scripts) for time-stamped temperature logging, alarm event capture, and CSV export. Optional MKN TempLog Pro software (v3.2+) provides configurable sampling intervals (1–300 s), real-time graphing, audit trail generation, and PDF report export compliant with ALCOA+ principles. All logged data retain metadata including operator ID, instrument serial number, calibration certificate ID, and environmental timestamp—supporting full traceability for GMP/GLP audits.
Applications
- Maintenance of bacterial, fungal, and yeast stock cultures (e.g., ATCC strains) at defined temperatures (e.g., 30 °C for Aspergillus niger, 37 °C for E. coli DH5α).
- Incubation of agar plates post-streaking or pour-plating in antimicrobial susceptibility testing (AST) per CLSI M07-A11 guidelines.
- Seed germination assays in plant physiology research under controlled thermal regimes.
- Pre-incubation of ELISA plates and immunoassay reagents prior to detection steps.
- Stabilization of pH electrodes and reference standards before calibration in analytical chemistry labs.
- Short-term storage of clinical specimens (e.g., stool, sputum) prior to microbial isolation—aligned with ISO 15189:2022 pre-analytical phase controls.
FAQ
What is the temperature uniformity specification across the working volume?
Temperature uniformity is ±0.8 °C at 37 °C (measured at 9 points per IEC 60068-3-5), verified during factory calibration.
Is the incubator compatible with CO₂ or humidity control modules?
No—the DHP-80 is a dry-air, non-humidified, ambient-atmosphere incubator. For CO₂ or humidity-dependent applications, consider the MKN CHP series.
Does the unit include NIST-traceable calibration documentation?
Yes—each unit ships with a factory calibration certificate (ISO/IEC 17025-accredited third-party verification optional upon order).
Can the incubator be validated for IQ/OQ/PQ protocols?
Yes—MKN provides validation templates aligned with ASTM E2500-22 and EU Annex 15; on-site qualification support is available via certified field service engineers.
What is the expected service life under continuous operation?
With scheduled preventive maintenance (biannual sensor verification and door gasket inspection), the unit maintains performance integrity for ≥8 years of 24/7 operation.
