F3G-5BGW-3 Three-unit 5L Bottom-Magnetic Stirred glass bioreactor

The F3G series bioreactor system is designed for conducting multiple process experiments simultaneously, providing an efficient solution for parallel fermentation research, process development and parameter optimization.

Available in F3G-JGW-X and F3G-BGW-X configurations, the system offers different agitation arrangements to accommodate varying material characteristics and experimental requirements. The vessel features a high-borosilicate glass body combined with 316L stainless steel components for the lid and base, supporting laboratory operation and off-site autoclaving.

Equipped with a 15.6-inch 2K embedded LED touchscreen and an intelligent PID fuzzy control system, the bioreactor enables centralized monitoring and precise regulation of critical process parameters. Its integrated agitation, aeration, feeding, temperature and dissolved oxygen management functions support flexible fermentation workflows.

Key Features & Advantages

Parallel Process Experimentation

Supports simultaneous exploration of multiple fermentation processes, helping researchers compare operating conditions and evaluate process parameters within the same experimental platform.

Integrated Functional Systems

1. Automatic Foam Detection and Defoaming

The integrated foam management system continuously detects foam levels and supports automatic defoaming treatment. Foam control can be performed using a defoamer or a dedicated defoaming pump, depending on the selected configuration.

2. Intelligent Process Control

Critical fermentation parameters are managed through an intelligent PID fuzzy control algorithm. This control approach helps maintain stable operating conditions and reduces parameter fluctuations during experimental processes.

3. Multi-Channel Aeration System

The bioreactor is equipped with a circular aeration ring at the bottom of the vessel. Additional aeration configurations are available, including optional four-channel gas supply and top-surface aeration.

Mass flow meters are provided for precise gas flow measurement and management of:

• Air

• Oxygen (O₂)

• Nitrogen (N₂)

• Carbon Dioxide (CO₂)

4. Exhaust Gas Condensation

An integrated exhaust condenser is included to support exhaust gas treatment during fermentation operation.

5. Variable-Speed Feeding System

The feeding system uses a variable-speed peristaltic pump for fed-batch fermentation processes. It supports different feeding strategies, including:

• Linear feeding

• Exponential feeding

• Multiple feeding modes

These options provide flexibility when developing and optimizing fermentation feeding procedures.

Optional Accessories and System Expansion

The F3G series supports additional modules and accessories to accommodate more advanced fermentation control, monitoring and analytical requirements.

Available optional configurations include:

Optional configurations can be selected according to the specific process, experimental objectives and automation requirements.

Application & Customization

The F3G series is suitable for parallel fermentation experiments, laboratory process development and fermentation parameter optimization. Its configurable vessel volumes, alternative agitation structures and expandable monitoring modules allow users to adapt the equipment to different research and process development needs.

Tank volume, tank quantity, diameter-to-height ratio and optional functional modules can be customized upon request.

For configuration selection and technical inquiries, please provide your required vessel volume, agitation method, number of parallel tanks and desired monitoring or automation functions.
