Overview
The JingHong DNP-9082 is a benchtop microprocessor-controlled incubator engineered for stable, repeatable thermal environments in life science laboratories. It operates on convection-based air circulation—optimized via internal airflow design and insulated chamber walls—to maintain precise temperature setpoints across its 80 L stainless steel working chamber. Designed for routine microbiological culture, cell maintenance, enzyme activity assays, and short-term sample storage, the DNP-9082 delivers consistent thermal performance without forced-air fan interference, minimizing vibration-sensitive disturbance to delicate biological samples. Its operational range—from ambient +5°C to 65°C—covers standard mesophilic culturing conditions (e.g., E. coli at 37°C), fungal growth (25–30°C), and accelerated stability testing protocols requiring elevated temperatures.
Key Features
- Microprocessor-based PID temperature controller with dual digital LED display—simultaneously showing setpoint and real-time chamber temperature for immediate verification and traceability.
- PID auto-tuning function enables adaptive response to load changes, door openings, or ambient fluctuations—ensuring rapid recovery and long-term stability.
- Dual-door configuration: outer insulated door and inner tempered glass door allow visual monitoring without compromising thermal integrity or introducing drafts.
- 100% stainless steel interior chamber—non-porous, corrosion-resistant, and compatible with common laboratory disinfectants (e.g., 70% ethanol, diluted sodium hypochlorite).
- Robust insulation system minimizes external heat transfer and reduces energy consumption during extended operation.
- Front-accessible control panel with intuitive push-button interface—designed for glove-compatible operation and minimal training requirements.
Sample Compatibility & Compliance
The DNP-9082 supports standard petri dishes (up to 150 mm), multi-well plates (6–96-well), culture flasks (T25–T175), and test tubes stored in racks. Its uniform temperature distribution (±0.5°C across the entire chamber volume, verified per ISO 15265:2019 Annex B methodology) ensures reproducible growth kinetics and assay outcomes. While not certified for GMP manufacturing environments, the unit meets general laboratory equipment requirements under ISO/IEC 17025:2017 for calibration traceability of temperature sensors and supports GLP-compliant documentation when paired with external data loggers. It complies with IEC 61010-1:2010 safety standards for electrical equipment used in laboratory settings.
Software & Data Management
The DNP-9082 operates as a standalone instrument with embedded firmware—no proprietary software required. All temperature parameters are locally stored in non-volatile memory and retained during power interruption. For audit-ready recordkeeping, users may integrate optional external USB or RS-485 data loggers compliant with FDA 21 CFR Part 11 guidelines (when configured with electronic signature and audit trail functionality). The device supports time-stamped manual logging via lab notebooks or LIMS-compatible spreadsheets using the dual-display readout as a primary source of truth.
Applications
- Routine bacterial and yeast cultivation in clinical microbiology and academic research labs.
- Short-term incubation of immunological assays (e.g., ELISA plate development at 37°C).
- Seed germination studies and plant tissue culture pre-incubation steps.
- Enzyme kinetic experiments requiring controlled thermal activation (e.g., restriction digests, ligase reactions).
- Stability assessment of reagents, buffers, and diagnostic kits under accelerated aging conditions (40–65°C).
- Quality control testing in pharmaceutical secondary packaging validation (per USP environmental conditioning).
FAQ
Is the DNP-9082 suitable for CO₂-dependent cell culture?
No. This is a dry-air, temperature-only incubator without CO₂ regulation, humidity control, or gas-tight sealing.
Can it be stacked or installed in enclosed cabinetry?
No. Minimum 10 cm clearance is required on all sides—including rear—for adequate heat dissipation and ventilation.
What calibration documentation is provided?
A factory-issued temperature verification report (at 37°C and 55°C) is included, traceable to NIM (National Institute of Metrology, China) standards.
Does it support remote monitoring or network connectivity?
Not natively. Integration with building management systems or SCADA networks requires third-party analog/digital I/O modules and custom configuration.
Is stainless steel shelving included?
Yes—two adjustable, load-rated stainless steel shelves are supplied standard; additional shelves can be ordered separately.
