Flexicon PD12L with MC12-B Controller – Product Introduction

The Flexicon PD12L with MC12-B Controller is a high-precision peristaltic filling and dispensing system designed for aseptic liquid handling in pharmaceutical, biotechnology, food, and laboratory environments. Combining the robust PD12L pump head with the intelligent MC12-B master controller, the system delivers exceptional accuracy, contamination-free operation, and flexible integration into automated production lines.

At its core, the PD12L operates on the peristaltic pumping principle, where fluid is transferred through a flexible tube compressed by rotating rollers. This design ensures that the liquid only contacts the tubing and filling path, eliminating any direct contact with mechanical pump components. As a result, the system is ideally suited for sterile, sensitive, or high-purity applications where cross-contamination must be strictly avoided.

The MC12-B controller serves as the central control unit of the system, enabling precise programming, monitoring, and synchronization of filling operations. It supports multiple operating modes, including single fill, multi-cycle dispensing, and continuous production mode. Through its intuitive interface, operators can configure parameters such as fill volume, speed, cycle timing, and calibration settings with high repeatability.

One of the key advantages of the PD12L system is its high dosing accuracy, typically reaching ±0.5% for standard volumes above 0.5 mL. This level of precision is achieved through advanced motor control, stable tubing compression geometry, and real-time calibration feedback via the MC12-B controller. The system can also automatically compensate for variations in tubing elasticity and fluid viscosity, ensuring consistent performance over long production runs.

The PD12L is widely used in aseptic filling applications, including vial filling, reagent dispensing, diagnostic kit production, and laboratory sample preparation. Because the tubing is disposable and easily replaceable, the system significantly reduces cleaning requirements and downtime between different product batches. Tube changeovers can typically be completed within minutes, making it highly efficient for multi-product environments.

The MC12-B controller enhances operational efficiency through its ability to manage multiple dispensing heads simultaneously. In industrial configurations, a single controller can coordinate up to 16 PD-series pump units, allowing scalable production from laboratory-scale development to full industrial filling lines. The controller also supports integration with external systems such as PLCs, balances, and printers, enabling full process automation and data traceability.

Another important feature of the system is its user-programmable recipe management. Operators can store multiple filling profiles for different products, including parameters such as fill volume, pump speed, acceleration profile, and cycle delay. This ensures rapid product switching while maintaining consistent quality control standards.

From a mechanical standpoint, the PD12L pump head is constructed using corrosion-resistant materials such as anodized aluminum and stainless steel components. It is designed for durability and long service life under continuous operation. The pump head is optimized to minimize pulsation effects, ensuring smooth and stable fluid flow even at high dispensing speeds.

Safety and compliance are also key aspects of the system design. The closed tubing system ensures that liquids are fully isolated from mechanical components, reducing contamination risks and supporting compliance with GMP and pharmaceutical manufacturing standards. Additionally, the system supports sterile tubing sets that are pre-packaged and traceable, further enhancing regulatory compliance.

In summary, the Flexicon PD12L with MC12-B Controller is a versatile and reliable solution for precision liquid handling. Its combination of aseptic design, programmable control, high accuracy, and modular scalability makes it a preferred choice for laboratories and production environments requiring both flexibility and strict process control.
