Overview
The YSEI DHPF-9135 Electric Constant Temperature Incubator is a precision-engineered laboratory incubation system designed for stable, uniform thermal control in life science research and quality-assured biological workflows. Based on resistive heating with PID-controlled air circulation, the DHPF-9135 maintains setpoint accuracy within ±0.5 °C across its working temperature range (typically ambient +5 °C to 65 °C — verified per IEC 61000-4-3 and ISO/IEC 17025 calibration practices). Its insulated double-wall construction and optimized airflow distribution minimize thermal gradients (<±0.8 °C uniformity at 37 °C), ensuring reproducible growth conditions for sensitive biological samples. The unit is purpose-built for applications requiring long-term stability without active humidity or CO₂ control — distinguishing it from multi-parameter incubators while delivering robust performance in resource-constrained or high-throughput environments.
Key Features
- Microprocessor-based PID temperature controller with digital LED display and intuitive keypad interface
- Independent overtemperature cut-off circuit — failsafe hardware protection separate from main control loop
- High-efficiency axial fan with noise-dampened housing (operating sound level <45 dB(A) at 1 m)
- Energy-optimized heating system with thermal insulation exceeding 45 mm polyurethane foam (thermal conductivity ≤0.022 W/m·K)
- Stainless steel inner chamber (AISI 304) with rounded corners for easy cleaning and contamination control
- Double-layer tempered glass observation window with anti-fog coating for continuous visual monitoring
- Adjustable stainless steel shelving (standard configuration: 2 shelves, load capacity ≥15 kg/shelf)
Sample Compatibility & Compliance
The DHPF-9135 supports a broad spectrum of non-humidified, aerobic biological processes including bacterial and fungal culture (e.g., E. coli, S. cerevisiae), plant tissue explant maintenance, insect rearing (Drosophila, Tribolium), small-mammal neonatal support (non-invasive holding), and biochemical assay incubation (e.g., enzyme kinetics, BOD testing). It complies with general electrical safety requirements per GB 4793.1–2007 (equivalent to IEC 61010-1) and electromagnetic compatibility per GB/T 18268.1–2010 (IEC 61326-1). While not certified for GLP/GMP production environments, its design supports audit-ready documentation when integrated into validated laboratory workflows under ISO/IEC 17025 or CAP-accredited quality systems. Temperature mapping reports and calibration certificates (traceable to NIM, China) are available upon request.
Software & Data Management
The DHPF-9135 operates as a standalone instrument with no embedded data logging or network connectivity. However, its analog voltage output (0–5 V DC corresponding to 0–65 °C) enables integration with external data acquisition systems (e.g., LabVIEW, DAQmx, or SCADA platforms) for time-stamped temperature trending and alarm triggering. Optional RS-485 Modbus RTU interface (add-on module) permits remote parameter readout and setpoint adjustment via serial command protocol — supporting centralized lab equipment monitoring where IT infrastructure permits. All operational parameters (setpoint, actual temperature, fault codes) remain visible on the front-panel display with real-time update frequency ≥1 Hz.
Applications
- Plant biology: Seed germination assays, callus induction, and photoperiod-independent seedling development
- Microbiology: Aerobic bacterial enumeration (ISO 4833-1), mold and yeast propagation (ISO 21527-1), and antibiotic susceptibility pre-incubation
- Environmental testing: Biochemical Oxygen Demand (BOD₅) incubation per APHA Standard Methods 5210B
- Agricultural R&D: In vitro embryo culture, pollen viability assessment, and rhizobial inoculant stabilization
- Veterinary & aquaculture: Fish egg incubation, larval rearing support, and probiotic strain maintenance
- Industrial QC: Stability testing of diagnostic reagents and enzyme-based kits under accelerated aging protocols
FAQ
What is the maximum operating temperature of the DHPF-9135?
The unit is rated for continuous operation up to 65 °C, with thermal stability maintained per manufacturer specifications under standard ambient conditions (25 °C, 50% RH).
Does the incubator include humidity control?
No — the DHPF-9135 is a dry-air, constant-temperature incubator. Relative humidity is uncontrolled and will equilibrate with ambient conditions.
Can the DHPF-9135 be used for CO₂-dependent cell culture?
No — it lacks gas-tight sealing, CO₂ injection capability, and pH-sensitive monitoring; it is unsuitable for mammalian monolayer culture.
Is third-party calibration supported?
Yes — the unit features a calibrated PT100 sensor (Class B tolerance) and accommodates external probe validation using NIST-traceable reference thermometers.
What power supply requirements apply?
Standard configuration: 220 V AC ±10%, 50 Hz, single-phase; maximum input power draw ≤500 W at full load.
