Yiheng DHP-9012 Series Forced-Air Benchtop Incubator

Overview

The Yiheng DHP-9012 Series is a precision-engineered forced-air benchtop incubator designed for reliable, stable thermal environments in cell culture, microbiological growth, enzyme assays, and general life science applications. Utilizing convection-based heat transfer with an optimized air circulation system, the unit maintains consistent temperature distribution across its 16 L chamber—critical for reproducible biological outcomes. The incubator operates within a controlled range of RT+5°C to 65°C, with a temperature resolution of 0.1°C and fluctuation limited to ±0.5°C under steady-state conditions. Its mirror-finish stainless steel interior ensures corrosion resistance, ease of decontamination, and compatibility with standard laboratory cleaning protocols. Engineered for daily use in academic labs, QC facilities, and R&D environments, the DHP-9012 prioritizes operational safety, energy efficiency, and long-term thermal stability without requiring external cooling or humidity control.

Key Features

• Microprocessor-based fuzzy PID temperature controller delivering high repeatability and minimal overshoot during setpoint transitions.
• Forced-air convection system with automatically modulated fan speed—reducing airflow intensity during thermal equilibrium to minimize sample desiccation while maintaining uniformity (±1.5°C at 37°C).
• Double-door design: outer insulated door with inner tempered glass observation window; heating and fan functions interlocked to halt automatically upon glass door opening—preventing thermal shock and eliminating temperature overshoot.
• Independent over-temperature cut-off circuit (optional), compliant with IEC 61000-4-2/4-3 EMC standards, providing hardware-level protection independent of main control logic.
• Configurable timer function with up to 99 hours 59 minutes programmable duration, supporting unattended overnight or extended incubation cycles.
• Heating via embedded stainless steel-sheathed resistive elements mounted on rear wall—ensuring rapid warm-up and even radiant-conductive heat distribution.

Sample Compatibility & Compliance

The DHP-9012 accommodates standard Petri dishes, multi-well plates (6–96-well), flasks (T25–T75), and test tubes without spatial interference. Its 16 L chamber supports up to two adjustable stainless steel shelves (included), each rated for 15 kg static load. All internal surfaces meet ISO 14644-1 Class 8 cleanroom material requirements for non-shedding and low particulate generation. While the unit does not provide active humidity control, its sealed construction minimizes ambient moisture exchange—making it suitable for low-humidity-sensitive protocols such as bacterial colony isolation or dry-heat pre-incubation steps. Optional UV-C germicidal irradiation (254 nm, 15 W lamp) enables periodic decontamination of circulating air and interior surfaces, supporting adherence to GLP-aligned aseptic practices. The device complies with GB/T 14710-2009 (Chinese Environmental Adaptability Standard for Medical Electrical Equipment) and conforms to CE marking directives for laboratory equipment (2014/30/EU EMC, 2014/35/EU LVD).

Software & Data Management

The base model features a single-setpoint digital interface with LED display. Optional upgrades include a multi-segment programmable LCD controller (up to 7 programs × 9 steps, total 63 segments), enabling ramp-soak profiles, scheduled start/stop, and variable fan-speed mapping per temperature stage. Data logging is supported via optional RS485 interface (Modbus RTU protocol) or embedded thermal printer (real-time timestamped output). A USB data export module (U-disk logger) records temperature history at user-defined intervals (1–60 min), generating CSV files compatible with Excel, MATLAB, or LIMS platforms. All optional communication modules support audit-trail-capable event logging—including parameter changes, door openings, alarm triggers, and power interruptions—in alignment with FDA 21 CFR Part 11 electronic record requirements when deployed with validated software configuration.

Applications

This incubator serves core workflows across academic, clinical, and industrial life science settings: mammalian and insect cell line propagation (e.g., HEK293, Sf9); aerobic and facultative anaerobic bacterial culture (E. coli, Bacillus spp.); fungal growth studies (Aspergillus, Candida); enzyme activity assays requiring precise thermal activation; seed germination testing; and reagent pre-warming prior to ELISA or PCR setup. Its compact footprint and stable thermal performance make it ideal for shared-core facilities where space and cross-contamination risk must be minimized. The absence of humidification avoids condensation-related issues in long-term cultures, while the UV option extends utility into sterile technique training and low-biocontainment mycology labs.

FAQ

Does the DHP-9012 support humidity control?
No—this is a dry-air incubator. Humidity is not regulated or monitored. For humidity-dependent applications (e.g., stem cell culture), a dedicated CO₂/humidified incubator is recommended.
Can the unit be validated for GMP environments?
Yes—when equipped with optional data logging (USB or RS485), IQ/OQ documentation templates are available upon request. Temperature mapping per ISO 14159 and alarm response verification can be performed using external calibrated probes.
What safety certifications does it carry?
It meets CE marking requirements under the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU). It is not UL-listed or FDA-cleared as a medical device, but is widely used in research-grade applications globally.
Is calibration traceable to national standards?
Factory calibration uses NIST-traceable reference thermometers. End-users may perform field verification using accredited PT100 sensors; calibration certificates are issued upon request for an additional fee.
Are spare parts and service support available outside China?
Global distributor networks provide technical support and consumables (glass doors, UV lamps, fuses, fan assemblies). Firmware updates and controller diagnostics are accessible via Yiheng’s secure portal with registered serial number authentication.
