Multipurpose membrane filtration system for pilot testing
Optimize your pilot-scale processes with a versatile filtration system that supports valuable product purification, ensuring precise separation and concentration for diverse applications like biopharmaceuticals and plant-based formulations.

Performs Membrane Filtration and Concentration
The Alfa Laval PilotUnit Multi is a versatile skid-mounted membrane filtration system designed for precision filtration challenges across various industries such as pharmaceuticals, biotech, and food and beverage. It offers a comprehensive solution by allowing you to test and scale processes for microfiltration, ultrafiltration, nanofiltration, and reverse osmosis in both batch and semi-batch modes. This system integrates seamlessly into your existing production line with its PLC-based control and data logging capabilities for enhanced automation and process monitoring.
With a membrane area that ranges from 3 to 15 m², and the ability to handle volumes between 50 and 1000 liters, the PilotUnit Multi is engineered to accommodate a wide range of viscosities and product types. The system features a robust stainless steel structure with easy maneuverability, including a pump, heat exchanger, and control instruments to maintain optimal cross-flow rates, minimizing fouling. It is especially suitable for high-temperature and pH-tolerant applications, making it highly adaptable across different operational needs.
Common applications include the production of monoclonal antibodies, protein supplements, flavor enhancers, and plant-based milk alternatives like almond milk. The unit is customizable with options for online monitoring and additional membrane area through modules like the Alfa Laval LabStak™ M39H, facilitating increased throughput and experimentation with different membrane types. Its compact design and integrated components minimize space requirements while maintaining efficient energy consumption, and it meets industry standards such as GMP, ensuring reliable compliance in regulated environments.
