Yiheng BPH-9162 Precision Constant Temperature Incubator

Overview

The Yiheng BPH-9162 Precision Constant Temperature Incubator is an engineered solution for laboratories requiring stable, reproducible thermal environments for cell culture, microbiological growth, enzyme assays, and long-term stability studies. Designed around a six-side direct heating architecture and a high-efficiency forced convection system, the BPH-9162 ensures rapid temperature equilibration and minimal spatial gradients across its 160 L stainless steel chamber. Its operational range spans from ambient +5°C to 80°C, with a resolution of 0.1°C and a typical fluctuation of ±0.2°C under steady-state conditions—performance validated at the critical 37°C setpoint used in mammalian cell culture. The incubator complies with fundamental design principles outlined in ISO 13408-2 (aseptic processing environments) and supports GLP-compliant workflows through traceable temperature control, real-time diagnostics, and optional data logging interfaces.

Key Features

• Mirror-finish 304 stainless steel interior with radius-rounded corners (R-corner design) for seamless cleaning and reduced microbial retention.
• Digital PID temperature controller with intuitive menu-driven LCD interface; displays setpoint, actual temperature, elapsed time, and error codes simultaneously.
• Intelligent fan-speed modulation: automatically adjusts airflow intensity based on thermal load and setpoint, minimizing sample desiccation during extended incubation.
• Independent dual-limit temperature protection circuit: provides hardware-level overtemperature cutoff and audible/visual alarm independent of the main control loop.
• 25 mm diameter access port on left chamber wall for external sensor integration, gas line routing, or cable management without compromising seal integrity.
• Self-diagnostic firmware: detects and displays fault codes (e.g., sensor open-circuit, heater failure, fan stall) directly on the LCD panel for rapid troubleshooting.

Sample Compatibility & Compliance

The BPH-9162 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), with two adjustable stainless steel shelves included as standard. Its chamber geometry (500 × 380 × 750 mm internal) allows unobstructed stacking and airflow clearance above and below loaded trays. While not certified for Class II biosafety applications, the unit meets essential electrical safety requirements per IEC 61010-1 and electromagnetic compatibility standards per IEC 61326-1. Optional UV germicidal irradiation (254 nm) can be integrated for periodic decontamination between runs—validated per ISO 15714 for surface microbial reduction. For regulated environments, the optional RS485 interface supports Modbus RTU protocol, enabling integration into centralized facility monitoring systems compliant with FDA 21 CFR Part 11 when paired with validated software.

Software & Data Management

The BPH-9162 supports multiple data acquisition pathways. A USB host port enables direct export of temperature/time logs to FAT32-formatted USB drives (U-disk), generating timestamped CSV files compatible with Excel, MATLAB, or LIMS platforms. Optional RS485 communication (Modbus RTU) permits bidirectional control and real-time parameter readout via LabVIEW, Python (PyModbus), or custom SCADA systems. An embedded thermal printer (optional) produces hard-copy records meeting ALCOA+ data integrity criteria—including date/time stamp, operator ID field (via front-panel input), and deviation alerts. All logged data retains audit trail capability when used with compliant third-party software, supporting GMP documentation requirements for stability testing per ICH Q5C and accelerated aging protocols per ISO 11137.

Applications

• Mammalian and insect cell culture maintenance at 37°C ± 0.5°C, with uniformity verified per ASTM E2876-22 (Standard Practice for Performance Testing of Laboratory Incubators).
• Bacterial and fungal cultivation (e.g., E. coli, S. aureus, C. albicans) across defined temperature gradients (25–45°C) for growth kinetics and antimicrobial susceptibility testing.
• Enzyme activity assays requiring precise thermal stabilization during kinetic measurements (e.g., ELISA, PCR pre-incubation, ligase reactions).
• Material stability assessment of pharmaceutical intermediates and excipients under ICH Q1A(R2) long-term and accelerated storage conditions.
• Environmental simulation for seed germination, soil microbiome studies, and biodegradation assays under controlled thermal regimes.

FAQ

What is the maximum operating temperature and does it support sterilization cycles?
The BPH-9162 has a maximum setpoint of 80°C. It is not designed for autoclave-grade sterilization (121°C); however, dry-heat decontamination up to 80°C for ≥2 hours is supported for non-critical surfaces.
Can the incubator maintain humidity control?
No—this model is a dry-air constant temperature incubator. Humidity control requires a separate humidified incubator (e.g., CO₂-capable units with steam injection).
Is the temperature uniformity specification valid across the full volume or only at the center?
Uniformity of ±1.5°C at 37°C is measured per ISO 13408-2 Annex D using nine-point mapping (center + eight peripheral locations), confirming compliance across the entire usable chamber volume.
Does the unit include validation documentation or IQ/OQ support materials?
Factory calibration certificates (NIST-traceable Pt100 sensor) are provided. Full IQ/OQ protocols and templates are available upon request for qualified customers adhering to GxP frameworks.
What safety certifications does the BPH-9162 hold for international use?
The unit conforms to IEC 61010-1 (safety) and IEC 61326-1 (EMC). CE marking is applied for EU markets; UL/cUL listing requires regional variant configuration and is not standard on base models.
