A fully automated bioprocessing system, providing flexibility and improved productivity in upstream and downstream single-use processing
Single-use technology continues to be adopted across many areas of bioprocessing. The use of automation provides additional benefits in manufacture such as consistency in product quality, reduced labor costs and reduction of operator errors.
The Allegro MVP system is designed for use across a range of bioprocessing activities such as:
Media and buffer preparation
최종 조제 및 충전
The Allegro MVP system uses fully disposable flowpaths, and incorporates single-use sensors for control and monitoring of key parameters. This enables processing to be conducted at optimum conditions, using fully automated process sequences.
Good engineering design provides reliability, robust operation and minimizes risk of operator error
High degree of automation enables precise and consistent operation, control of key parameters, and minimizes operator contact
High degree of flexibility to run many different processes
The system was designed to perform the pH adjustment steps needed in media preparation and virus inactivation, with fully automated addition of acid & base stock solutions. Allegro mixers can be used with the MVP system, to ensure rapid dispersal of the added fluids during these process steps.
A large selection of pre-designed manifolds is available, with a specially designed manifold selection tool to help identify the most suitable manifold for your application.
A choice of sensors, connectors, tubing type, filters and pre-filters when selecting a flowpath ensures the manifold is completely suited to your process application.
No other system offers such a wide range of preconfigured standard manifold options.
The system is designed to automatically monitor multiple parameters and the following sensors can be selected:
Pressure (inlet, between filters, outlet single-use sensors)
pH (reusable probe in mixer)
Flow (inlet single-use sensors)
Conductivity (reusable probe in mixer or single-use sensor on outlet)
UV (outlet single-use sensors)
Mass (via load cell connection)
The sensors being used in any given process can be easily selected or deselected on the configuration screen. Sensors not being used are not shown on the main operating screen.
The phase editor in the control system allows the generation and configuration of customer specific processes in a simple and user-friendly way. This facilitates reliable, automated control of processing at optimum conditions.
Allegro MVP System capabilities:
최종 조제 및 충전
Media and buffer preparation (mixing, pH adjust, filtration)
Virus filtration and inactivation
A universal clamp can be used to support capsules with diameter 5 cm to 10.5 cm
Different capsule types
Filters in series / parallel
Vertical brackets can be moved horizontally to give flexibility with any manifold design
Depending on the process application and the flow range required, either a diaphragm or a peristaltic feed pump can be used with the Allegro MVP system.
Capsules with a diameter 5 cm to 10.5 cm (up to 30 in. Pall Kleenpak™ Nova filter or equivalent) are supported on the Allegro MVP system with universal clamps fixed to vertical brackets. This allows for different filter combinations and running filters in series or parallel.
Stax™ depth modules (up to 20 m2) can be positioned next to the Allegro MVP system, with connections running between the units.
Automated pH Adjustment
The Allegro MVP system has two small pumps which add acid/base as programmed by the software.
The acid and base stock solutions are located in the two 20 L trays.
Mixing is required for virus inactivation and media preparation. An Allegro mixer bag with acid/base ports and pH probe access point can be used with this system. The mixer can be controlled from the HMI on the MVP system.
A reusable, autoclavable, pH probe in the mixing bag will continually monitor the pH, so that the end point can be accurately determined.
Intuitive Flowpath Installation
Unique, intuitive, labelling on the Allegro MVP manifolds ensures quick and easy installation of flowpaths and filters in the correct location.
