YiHeng BPC-250F Biochemical Incubator

Overview

The YiHeng BPC-250F Biochemical Incubator is an air-jacketed, compressor-cooled laboratory incubator engineered for precise, stable, and contamination-controlled environmental conditioning of biological samples. Designed in accordance with ISO 13485-aligned manufacturing practices and aligned with GLP-compliant operational requirements, it delivers reliable thermal performance across a broad operating range (−5 °C to 70 °C), supporting applications including microbial cultivation, enzyme activity assays, biochemical reaction kinetics, and long-term stability studies. Its natural convection architecture eliminates forced-air turbulence that may desiccate sensitive cultures or disrupt sedimentation-based assays—making it particularly suitable for non-agitated cell culture, fungal growth, and reagent storage where airflow-induced evaporation must be minimized. The unit’s monolithic polyurethane foam insulation ensures low thermal leakage and high energy efficiency, while its mirror-finish stainless-steel interior (with radius-corner transitions) facilitates rapid decontamination and meets standard cleanroom-compatible surface criteria.

Key Features

• Air-jacketed heating system with independent compressor-based cooling enables simultaneous heating and cooling control—critical for maintaining setpoints near ambient or below zero.
• Fuzzy PID temperature controller with programmable timer (up to 99 h 59 min) ensures minimal overshoot and high reproducibility (<±0.3 °C fluctuation at elevated setpoints).
• Three-speed adjustable natural convection fan allows optimization of internal air movement—reducing sample desiccation during extended incubations without compromising uniformity.
• Integrated self-diagnostic system displays real-time fault codes on the backlit LCD interface, enabling rapid identification of sensor drift, compressor anomalies, or heater failures.
• Multi-segment programmable controller supports up to 7 programs, each comprising 9 steps (63 total steps), with independent configuration of temperature, dwell time, and ramp rate—enabling gradient-based protocols such as cold acclimation or thermal stress profiling.
• Dedicated 25 mm access port on left chamber wall permits external probe insertion or cable routing without compromising seal integrity or thermal stability.

Sample Compatibility & Compliance

The BPC-250F accommodates standard-sized culture vessels—including Petri dishes, multi-well plates, Erlenmeyer flasks (up to 2 L), and serum bottles—within its 300 L usable chamber volume (520 × 550 × 1050 mm). Its stainless-steel interior complies with ASTM F1526-21 standards for biocompatible surfaces, and optional UV germicidal irradiation (254 nm) provides supplementary air and surface decontamination between runs—supporting ISO 14644-1 Class 8 clean environment maintenance when operated in controlled laboratories. The unit meets IEC 61010-1 safety requirements for laboratory equipment and incorporates dual independent temperature monitoring: primary control sensor plus redundant overtemperature cut-off circuitry (audible/visual alarm at user-defined threshold), satisfying essential risk mitigation criteria under FDA 21 CFR Part 11 Annex 11 for audit-trail-capable instrumentation.

Software & Data Management

While the BPC-250F operates via embedded firmware with no proprietary software dependency, it supports traceable data acquisition through optional interfaces: RS-485 Modbus RTU protocol for integration into centralized building management or LIMS systems; USB host port for direct export of time-stamped temperature logs to FAT32-formatted USB drives; and analog output (0–5 V or 4–20 mA) for connection to external chart recorders or PLCs. All logged data includes timestamp, setpoint, actual chamber temperature, and event flags (e.g., door open, alarm trigger), fulfilling minimum ALCOA+ data integrity principles for regulated environments. Optional thermal printer support enables hard-copy generation of validation reports compliant with ISO/IEC 17025 documentation requirements.

Applications

• Microbial growth studies (bacteria, yeasts, molds) under defined thermal regimes
• Biochemical assay incubation requiring stable sub-ambient temperatures (e.g., cold-active enzyme characterization)
• Stability testing of diagnostic reagents, vaccines, and biologics per ICH Q1A(R2)
• Environmental simulation for ecotoxicology or soil microbiome research
• Pre-incubation conditioning of media, buffers, and agarose gels prior to electrophoresis or plating
• Long-term storage of temperature-sensitive reference standards and calibration materials

FAQ

Does the BPC-250F support humidity control?
No—this model is a dry incubator. Humidity control requires separate vapor generator integration or selection of YiHeng’s dedicated humidified incubator series (e.g., HPS series).
Can the unit operate continuously at −5 °C in ambient environments above 30 °C?
Yes, provided adequate ventilation clearance (≥10 cm on all sides) and ambient relative humidity remains below 80% RH non-condensing.
Is the UV lamp included as standard equipment?
No—UV sterilization is an optional accessory. When installed, it operates independently of temperature control and features manual activation with automatic shutoff after 30 minutes.
What calibration documentation is supplied?
Each unit ships with a factory calibration certificate referencing NIST-traceable standards, covering temperature uniformity and fluctuation verification at three points (center, top-left, bottom-right) per ISO 17025 procedures.
How is firmware updated?
Firmware updates are performed via USB drive using YiHeng’s certified update utility; no network connectivity or cloud interface is implemented—ensuring air-gapped security for regulated labs.
