YIHENG BPH Series Precision Temperature and Humidity Controlled Incubator for Cell Culture

Overview

The YIHENG BPH Series Precision Temperature and Humidity Controlled Incubator is engineered for reliable, long-term cell culture, microbiological growth, and tissue-based assays under tightly regulated thermal conditions. Designed in accordance with ISO 13485-aligned manufacturing practices and validated for GLP-compliant laboratories, this incubator employs a forced-air convection system with microprocessor-controlled PID regulation to maintain uniform temperature distribution across the chamber—critical for reproducible mammalian cell proliferation, stem cell expansion, and primary culture maintenance. Unlike basic dry incubators, the BPH series integrates high-fidelity environmental control architecture, including real-time monitoring of internal thermal gradients, programmable ramp-and-hold profiles (optional), and passive humidity retention via stainless-steel chamber design—making it suitable for applications requiring minimal CO₂-independent stability, such as insect cell lines, fungal cultures, or non-CO₂-dependent hybridoma work.

Key Features

• Intuitive 4.3-inch backlit LCD interface with menu-driven navigation—displays setpoint, actual temperature, timer status, and diagnostic codes simultaneously.
• Mirror-finish 304 stainless-steel interior with radius-cornered construction (R ≥ 15 mm) and removable shelf supports—enabling complete decontamination and compliance with ISO 14644-1 Class 7 cleanroom-compatible cleaning protocols.
• Optimized horizontal airflow ducting with variable-speed centrifugal fan—dynamically adjusts air velocity based on thermal load to minimize evaporative stress on open petri dishes and flasks without compromising uniformity (±0.2 °C at 37 °C, measured per ASTM E2797-21).
• Fault-tolerant fuzzy PID controller with dual-stage heating algorithm—ensures rapid recovery after door openings (<6 min to re-stabilize at 37 °C, per IEC 61000-4-2 testing conditions) and eliminates overshoot during ramp cycles.
• Dual independent alarm system: primary temperature deviation alert (±1.0 °C from setpoint) and secondary hardware-limit cutoff (programmable upper threshold up to 85 °C), both accompanied by visual LED indicators and audible beeper (85 dB @ 30 cm).
• Standard 25 mm diameter access port on left sidewall—pre-drilled and gasket-sealed for integration with external sensors, gas lines, or data loggers without compromising chamber integrity.

Sample Compatibility & Compliance

The BPH incubator accommodates standard life science consumables—including T-25 to T-225 flasks, 6–96-well plates, Petri dishes (up to 150 mm), roller bottles, and multi-layer cell factories—across all four model variants (BPH-9042 to BPH-9272). Chamber volume ranges from 39 L to 252 L, supporting scalable workflows from benchtop R&D to pilot-scale bioproduction. All models comply with IEC 61010-1:2010 safety requirements for laboratory equipment and meet electromagnetic compatibility standards per EN 61326-1:2013. Optional UV-C germicidal irradiation (254 nm, 15 W lamp) provides supplementary surface decontamination between runs, supporting adherence to CLSI M22-A3 and USP environmental control guidelines for aseptic processing areas.

Software & Data Management

Equipped with RS-485 Modbus RTU interface (optional), the BPH series enables seamless integration into centralized lab infrastructure via third-party SCADA or LIMS platforms. The built-in USB host port accepts FAT32-formatted USB flash drives for autonomous logging of time-stamped temperature records at user-defined intervals (1 s to 60 min resolution). Data exports as CSV files compatible with Excel, MATLAB, or Python pandas analysis pipelines. When paired with optional YIHENG CommSoft v3.2, users gain audit-trail-enabled operation—meeting FDA 21 CFR Part 11 requirements for electronic records through password-protected user roles, immutable event logs, and digital signature support. Print output via integrated thermal printer (optional) produces traceable hardcopy reports compliant with ISO/IEC 17025 documentation standards.

Applications

• Mammalian cell line maintenance (HEK293, CHO-K1, HeLa) under serum-containing or serum-free media formulations.
• Bacterial and yeast culture propagation for plasmid amplification, protein expression screening, and fermentation inoculum preparation.
• Embryoid body formation and organoid differentiation protocols requiring extended thermal consistency (>72 h).
• Stability studies of biologics, vaccines, and diagnostic reagents per ICH Q5C guidelines.
• Environmental simulation for accelerated aging tests of medical device packaging materials (ASTM F1980).
• Seed germination and plant tissue culture in phyto-laboratories where CO₂ supplementation is not required.

FAQ

What is the maximum allowable ambient temperature for continuous operation?
The unit is rated for uninterrupted use at ambient temperatures between +5 °C and +35 °C, with relative humidity ≤ 80 % RH non-condensing.
Can the incubator maintain humidity levels?
The BPH series is a temperature-controlled incubator with passive humidity retention only; active humidification is not included. For precise RH control, consider pairing with an external saturated salt chamber or upgrading to the YIHENG BHV series.
Is validation documentation available for IQ/OQ/PQ protocols?
Factory-supplied DQ/IQ templates and calibration certificates (NIST-traceable thermistor probes) are provided. Full OQ/PQ execution requires site-specific sensor mapping and is supported by YIHENG’s qualified field service engineers.
Does the unit support remote monitoring over Ethernet or Wi-Fi?
Native Ethernet/Wi-Fi is not integrated; however, RS-485 connectivity allows bridging to industrial gateways (e.g., MOXA EDS-G205A) for TCP/IP translation and cloud-based dashboard visualization.
What is the warranty coverage and service response time?
Standard 24-month parts-and-labor warranty applies. Priority technical support is available via email and phone during business hours (GMT+8), with on-site service dispatch within 5 business days for major metro areas in APAC and EU regions.
