Overview
The Yiheng DHP-9162B Forced-Air Biochemical Incubator is an engineered solution for precise, stable, and reproducible temperature-controlled environments in life science laboratories. Designed according to standard biochemical incubation protocols, it employs a forced-air convection system with automatically regulated fan speed to ensure rapid thermal equilibration and minimal spatial gradient across the chamber. The unit operates on the principle of resistive heating via embedded electric heating films on mirror-finish stainless steel interior walls—providing uniform heat distribution without hot spots or cold zones. Its microprocessor-based temperature controller delivers real-time monitoring and closed-loop feedback control, enabling consistent performance across extended operational cycles. Intended for non-refrigerated applications, the DHP-9162B supports routine cell culture maintenance, microbial growth studies, enzyme activity assays, and stability testing under ambient-plus conditions compliant with ISO 13408-2 and CLSI M22-A3 guidelines.
Key Features
- Mirror-finish stainless steel interior chamber for corrosion resistance, ease of cleaning, and optical clarity during observation.
- Double-glazed inner glass door with interlocked safety logic: automatic suspension of heating and fan operation upon door opening to prevent thermal overshoot and maintain process integrity.
- Intelligent fan-speed modulation system—dynamically adjusts airflow velocity based on setpoint deviation and load condition to minimize sample desiccation and mechanical stress on delicate cultures.
- Dual-stage temperature control architecture: primary PID-regulated heating loop supplemented by an independent overtemperature cut-off circuit (optional), meeting IEC 61010-1 Class II safety requirements for laboratory equipment.
- Programmable timer function (1–9999 minutes) with auto-start capability for unattended overnight or multi-day incubation protocols.
- Standard RS485 serial interface (optional) supporting Modbus RTU protocol for integration into centralized lab management systems and audit-ready data logging.
Sample Compatibility & Compliance
The DHP-9162B accommodates standard laboratory vessels including Petri dishes, multi-well plates (6–96-well), Erlenmeyer flasks (up to 2 L), and tissue culture flasks (T75–T225). Its 160 L working volume and optimized internal geometry allow stacking of up to four adjustable stainless steel shelves (two included; additional trays available). Chamber humidity remains passive (non-controlled), making the unit suitable for applications where moisture retention is managed externally (e.g., via humidified containers or sealed culture vessels). The device complies with GB/T 23792–2009 (Chinese national standard for biochemical incubators) and conforms to electromagnetic compatibility (EMC) requirements per EN 61326-1:2013. Optional UV-C germicidal irradiation module (254 nm) enables periodic decontamination of interior surfaces, supporting GLP-compliant facility hygiene practices.
Software & Data Management
While the base configuration features a standalone digital controller with LED display, optional connectivity modules enable traceable data acquisition. The RS485 interface—when paired with Yiheng’s proprietary LabLink™ communication software—supports real-time temperature streaming, historical trend visualization, and export of CSV-formatted logs compatible with LIMS platforms. For regulated environments, the optional printer module provides continuous thermal record output with timestamp, setpoint, and actual temperature values—satisfying basic documentation needs under FDA 21 CFR Part 11 Annex 11 principles when combined with procedural controls. Audit trail functionality is implemented at the system level through firmware-level event logging (power-on/off, door openings, alarm triggers, parameter changes), accessible via secure USB export.
Applications
- Bacterial and fungal cultivation in microbiology labs (e.g., E. coli, S. aureus, C. albicans) at standardized temperatures (30°C, 35°C, 37°C).
- Enzyme kinetics and protein denaturation studies requiring stable thermal environments between 25°C and 60°C.
- Seed germination and plant tissue culture experiments under controlled ambient-plus conditions.
- Quality control testing of pharmaceutical excipients and biologics intermediates per USP environmental monitoring criteria.
- Long-term stability assessment of diagnostic reagents and ELISA kits per ICH Q1A(R2) guidelines.
FAQ
What is the maximum operating temperature of the DHP-9162B?
The unit is rated for continuous operation from ambient +5°C up to 65°C.
Does the incubator support humidity control?
No—this is a dry-air forced-convection incubator. Humidity must be maintained externally using sealed containers or supplemental humidification devices.
Is the temperature sensor calibrated to NIST-traceable standards?
Factory calibration is performed using reference-grade thermistors traceable to national metrology institutes; full recalibration services are available through authorized Yiheng service centers.
Can the DHP-9162B be integrated into a building management system (BMS)?
Yes—via optional RS485 Modbus RTU interface, enabling remote status monitoring and basic setpoint adjustment within BMS frameworks compliant with BACnet/IP or Modbus TCP gateways.
What safety certifications does this model hold?
It meets CE marking requirements under the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU), and carries CCC certification for the Chinese market (CQC19001033222).
