Overview
The Yoyilab DHP-9272 Forced-Air Biochemical Incubator is an engineered solution for stable, reproducible microbial and cell culture environments in academic, pharmaceutical, food safety, and industrial quality control laboratories. Designed around a robust forced-air convection system, it ensures rapid thermal equilibration and high spatial temperature uniformity—critical for consistent colony formation, enzyme activity assays, and long-term viability studies. The incubator operates within a precisely regulated range of RT+5°C to 65°C, with a resolution of 0.1°C and fluctuation tolerance of ±0.5°C under standard ambient conditions (30°C, 50% RH). Its 270 L working chamber accommodates multiple stacked culture vessels, Petri dishes, or flasks while maintaining compliance with fundamental biosafety and experimental integrity requirements for non-hazardous biological work.
Key Features
- High-efficiency forced-air circulation system with optimized airflow path design to minimize thermal gradients across the chamber
- Double-door structure with high-density insulation and magnetic rubber sealing gasket to reduce heat loss and maintain internal stability during observation
- Electropolished mirror-finish stainless steel interior (304 grade) with radius-corner construction for easy cleaning and contamination control
- Adjustable stainless steel shelving (standard configuration: 2–3 shelves, fully removable and repositionable)
- 5.7-inch LCD intelligent controller displaying real-time temperature, setpoint, elapsed time, and alarm status simultaneously
- Microprocessor-based PID temperature control with over-temperature deviation protection and automatic cut-off at user-defined safety limits (optional independent dual-limit thermostat available)
- Power-loss recovery function preserving set parameters and runtime data after unexpected shutdowns
- Integrated thermal insulation using high-performance polyurethane foam (≥50 mm thickness) and low-conductivity door seals for extended service life and energy efficiency
Sample Compatibility & Compliance
The DHP-9272 supports a wide range of biological samples including bacterial cultures (e.g., E. coli, Bacillus subtilis), fungal isolates, yeast suspensions, and mammalian cell lines requiring non-CO2, non-humidified incubation. Its temperature performance meets ASTM E1282-17 (Standard Practice for Performance Verification of Laboratory Incubators) and aligns with ISO 13408-1:2018 (Aseptic processing of health care products – Part 1: General requirements) for equipment used in microbiological testing workflows. While not certified for GLP/GMP production environments out-of-the-box, its optional RS485 interface and audit-trail-capable software package enable integration into FDA 21 CFR Part 11-compliant data management systems when paired with validated third-party platforms.
Software & Data Management
The standard controller provides local parameter logging and event-triggered alarms but does not include built-in data export. Optional accessories expand functionality: an RS485 serial interface (with Modbus RTU protocol support) allows connection to laboratory information management systems (LIMS) or SCADA platforms for centralized monitoring and trend analysis. An embedded thermal printer (optional) generates time-stamped hardcopy records of temperature profiles—useful for QC documentation in food microbiology or environmental monitoring labs. All firmware updates and configuration backups are performed via USB port; no cloud dependency or proprietary software installation is required.
Applications
- Routine bacterial enumeration (e.g., total viable count, coliform detection per ISO 4833-1, APHA Standard Methods)
- Incubation of selective/differential media (e.g., MacConkey Agar, Mannitol Salt Agar, TSA)
- Enzyme kinetics studies requiring precise thermal control between 30–45°C
- Seed stock maintenance and strain preservation at sub-optimal growth temperatures
- Stability testing of probiotics, enzymes, or diagnostic reagents
- Supporting ISO/IEC 17025-accredited microbiology testing laboratories where traceable temperature validation is mandatory
FAQ
What is the recommended calibration interval for the DHP-9272?
Annual calibration using NIST-traceable thermistors or PT100 probes is advised for ISO/IEC 17025 compliance; internal sensor verification can be performed quarterly using calibrated reference thermometers.
Can this incubator be used for BSL-2 applications?
No—it lacks HEPA filtration, negative pressure containment, or UV decontamination features required for BSL-2 pathogens; it is intended for non-pathogenic or risk-group 1 organisms only.
Is humidity control available as an upgrade?
Not natively; the DHP series is strictly dry-air incubation. For humidified operation, consider Yoyilab’s HCP-series CO2/humidity incubators.
Does the unit comply with electromagnetic compatibility (EMC) standards?
Yes—it conforms to IEC 61326-1:2013 for laboratory electrical equipment regarding emission and immunity performance.
What is the warranty coverage?
Standard 24-month parts-and-labor warranty from date of shipment; extended service contracts available upon request.
