Allegro™ Connect Buffer Management System
The Allegro Connect buffer management system provides buffer on demand. It is a flexible system designed for pilot scale, clinical batches and commercial production to ensure that the right buffer is delivered at the right time, providing an efficient, streamlined workflow. The modular system design enables up to six high volume process buffers to be supplied as required, one at a time, directly to the batch unit operation such as chromatography or tangential flow filtration (TFF) based on buffer inline-dilution (ILD) and utilizing a single-use flow path. Multi-column chromatography (MCC) application buffer requirements can also be met by the Allegro Connect buffer management system, delivering a maximum of four process buffers at the same time to the MCC chromatography system.

The standard system comprises of a control unit and two buffer workstations. Buffer concentrates are diluted in-line with water for injection (WFI) at point of use with typical dilution factors of 5x - 20x. These significantly smaller buffer volumes offer a reduced labor cost and alleviate the need for large mixing/hold vessels that take up a large overall footprint. The Allegro Connect buffer management system provides a reduction in capital expenditure.
The Allegro Connect buffer management system alleviates traditional bottlenecks in buffer preparation and provides a solution to the challenges faced as processes become increasingly intensified and the range of biotherapeutics becomes more diverse.

Performance
The Allegro Connect buffer management system has been designed to simplify and improve process buffer workflow by providing ‘just-in-time’ process buffer directly to the unit operation. Valuable floorspace is saved by using in-line dilution of buffer concentrates and water for injection (WFI) at point of use, to meet the target buffer specifications. Buffer workflow is simplified by eliminating the need to prepare and store large volumes of process buffer in advance. Operator workspace is improved with a more compact footprint around unit operations requiring high buffer volumes. Total buffer cost/L is reduced by up to 12%, attributable to a reduction in costs for labor, reagents and capex expenditure. The reduction in the overall footprint of buffer preparation/hold and storage vessels enables up to 75% valuable facility floor space savings.
The system has an additional option for bioburden protection, providing increased assurance against microbial contamination. Each in-specification buffer can be filtered prior to filling the process bag, with up to six single-use capsule filters with automated capsule venting to ensure ease-of-use. Additional protection can be achieved by using single-use manifolds with sterile connectors to maintain a low bioburden.
Designed for Ease of Use
The Allegro Connect buffer management system has undergone extensive user testing, to ensure the system is simple and intuitive to use, fits with operators’ existing workflows, and eliminates the risk of user error.
The system features on-screen visual instructions and shadow-boarding to guide users and ensure correct manifold installations of the single-use systems.
Inline monitoring of buffer concentrates acts as an additional safety check that manual installation activities have been successfully completed.
