YIHENG BPC Series Biochemical & Fungal Incubator with Multi-Stage Programmable LCD Controller

Overview

The YIHENG BPC Series Biochemical & Fungal Incubator is an engineered platform designed for precise, stable, and programmable environmental control in life science laboratories. Built on air-jacketed heating and compressor-based refrigeration architecture, it delivers reliable thermal regulation across a broad operational range (−5 °C to 70 °C), supporting both standard biochemical cultivation and stringent fungal growth studies requiring extended low-temperature stability. Its natural convection design eliminates forced-air turbulence—critical for sensitive cell cultures, microbial colonies, and enzyme activity assays where mechanical shear or desiccation must be minimized. The incubator complies with fundamental laboratory safety and performance expectations aligned with ISO 13485–informed manufacturing practices and supports GLP-aligned experimental traceability when integrated with optional data logging systems.

Key Features

• Air-jacketed heating system ensures rapid thermal response and minimal internal gradient formation during temperature transitions.
• Compressor-driven refrigeration enables consistent sub-ambient operation down to −5 °C—essential for psychrophilic organism studies and cold-chain validation protocols.
• Multi-stage programmable LCD controller supports up to 7 user-defined programs, each comprising 9 sequential steps (63 total steps), with adjustable parameters per step: target temperature, dwell time (0–5999 minutes), ramp rate, and fan speed level (3 settings).
• Fuzzy PID temperature control algorithm maintains high reproducibility, with documented fluctuation ≤ ±0.3 °C at elevated setpoints and ≤ ±0.5 °C at sub-zero conditions.
• Self-diagnostic interface displays real-time fault codes on the main LCD screen, enabling rapid identification of sensor anomalies, compressor faults, or door-open events.
• Dual independent over-temperature protection: primary control loop + hardware-based backup limiter with audible/visual alarm—meeting IEC 61000-6-2 EMC and basic functional safety requirements for Class II lab equipment.
• UV germicidal lamp (optional; standard on fungal-configured units) mounted at the chamber ceiling provides periodic decontamination of circulating air and interior surfaces, reducing airborne microbial load between experiments.

Sample Compatibility & Compliance

The BPC Series accommodates standard Petri dishes, multi-well plates, culture flasks (up to T225), and glassware up to 250 mm height. Its mirror-polished stainless-steel interior (304 grade), fully rounded corners, and removable shelf supports facilitate cleaning validation per ISO 14644 cleanroom maintenance guidelines. A 25 mm diameter pass-through port on the left side allows feedthrough of sensors, tubing, or power cables without compromising chamber integrity. While not certified to UL 61010-1 or EN 61010-1 as a standalone medical device, its construction and thermal management align with general-purpose laboratory equipment requirements under ANSI Z240.1. For regulated environments, optional USB data export and RS-485 interfaces support integration into 21 CFR Part 11–compliant audit trails when paired with validated third-party software.

Software & Data Management

The embedded controller logs temperature readings at user-selectable intervals (default: 1 minute) and stores up to 30 days of historical data internally. Optional connectivity includes:

• USB port for direct transfer to FAT32-formatted USB drives (no proprietary drivers required); exported CSV files contain timestamp, setpoint, actual temperature, and alarm status flags.
• RS-485 Modbus RTU interface for integration into building management systems (BMS) or centralized lab monitoring platforms.
• Parallel printer port (Centronics-style) enables real-time hardcopy output of temperature profiles during critical validation runs.

All data exports retain native time stamps synchronized to the onboard RTC, supporting retrospective analysis and deviation investigations per ALCOA+ principles.

Applications

This incubator serves diverse applications including: bacterial and fungal strain maintenance (e.g., Aspergillus niger, Candida albicans); enzymatic reaction kinetics under controlled thermal gradients; seed germination studies requiring diurnal cycling; long-term stability testing of biologics at intermediate storage conditions; and environmental simulation for ASTM D3574 foam aging protocols. Its −5 °C capability also supports cold acclimation studies in plant physiology and cryoprotectant optimization workflows.

FAQ

What is the maximum number of programmable temperature ramps supported?
Up to 63 discrete steps across 7 independent programs—each step configurable with temperature, duration, and ramp slope.
Is the UV lamp included by default?
UV sterilization is standard on models designated for fungal applications; it is optional on general biochemical variants.
Can the incubator operate continuously at −5 °C in ambient room conditions of 30 °C?
Yes—compressor cooling capacity has been validated for sustained operation at minimum setpoint under worst-case ambient load (30 °C / 70% RH).
Does the controller support password-protected parameter locking?
Yes—administrator-level access requires 4-digit PIN entry to modify program sequences or calibration offsets.
How is temperature uniformity verified during factory acceptance testing?
Using 9-point thermocouple mapping per ISO 14644-3 Annex B methodology, with all probes calibrated to NIST-traceable standards prior to chamber qualification.
