Allegro™ CM150 Auto Single-Use Tangential Flow Filtration System

Optimized small scale SUTFF processing

The Allegro CM150 Auto TMP control is a single-use tangential flow filtration (SUTFF) semi-automated system designed for pilot or small scale process ultrafiltration and diafiltration (UF/DF) applications at 2-20 L batch volumes.

The system layout is optimized for a low minimum recirculation loop, to ensure final target volumes can be achieved and provide excellent product recovery.

The programmable logic controller (PLC) based control system ensures easy operation and monitoring of UF applications, constant volume diafiltration, and provides real-time trending and data logging capabilities.
  • Designed for ease of use
  • Single-use sensors – Pressure, flow, conductivity, temperature, ultraviolet (UV)
  • Low feed / retentate volume ~100 mL
  • Excellent product recovery
  • 0.1 – 0.4 m2 cassette area

System Functionality

The Allegro CM150 Auto system is part of a broader range of SUTFF systems offered by Pall for processing 2 L to 2000 L batches. The system has the flexibility to run Cadence™ SUTFF modules or T-series Centramate™ cassettes with Omega™ or Delta membrane, and a dedicated kit offers the option to operate hollow fibers.

Scalability of performance is critical in developing tangential flow filtration (TFF) processes. The Allegro CM150 system is designed for use in small scale good manufacturing practice (GMP) manufacture and for process development activities, to generate scalable data. Continuity of single-use component choice and design approach across our system range provides reliable scale up from Allegro CM150 system to the larger scale Allegro SUTFF systems.

The system offers the flexibility needed for single-use processing. The base system can run with just pressure and flow sensors or utilize the additional optional sensors for conductivity, temperature and UV, depending on the process requirements. The base system accommodates this flexibility, and base systems can be upgraded later if additional features are needed for new projects.



All connections and key controls are easily accessible from the front of the system.

Performance

System Performance

The Allegro CM150 SUTFF system can process at typical crossflows of with 5 to 8 L/min/m2. It has a recirculation pump capacity of 150 L/Hour and can typically run 0.1 – 0.4 m2 cassettes (running at a crossflow of 5 L/min/m2). The system is supplied with retentate biocontainers to run 5-10 L batch volumes. Starting with larger volumes can be managed by running the system in a fed batch mode.

The data in figures 1 to 4 show the results from a x20 IgG concentration (starting concentration 10 g/L) and x5 diafiltration volumes with phosphate-buffered saline (PBS). The efficiency of the diafiltration was monitored by following the removal of 7% glucose added to the protein solution

The system showed good mixing, negligible foaming in the retentate biocontainer, and efficient diafiltration of the solution.

The system is fully drainable via the low point recovery valve.
