As Microspheres are extremely valuable medicines to develop and produce it is vital that drug manufacturers maximise their product recovery in order to secure their competitive position in the global market. The core features of our MSR™ system were designed with this crucial requirement in mind.

The product recovery method of our MSR™ MicroSphere Refiner is unique as it is fully automated and it does not require any manual product off-loading by operators through an aseptic isolator, for example. Being an all-in-one solution, the MSR™ method also minimises the number of transfers and connections to aid maximising product yield.

MSR Microsphere Refiner Product Recovery

The MSR™ is a Good Manufacturing Practice (GMP) piece of equipment, suited to multi-product applications. It is designed to allow end-users to remain agile and quickly adapt to changing production requirements.

MSR Microsphere Refiner Table

The implementation of Process Analytical Technology (PAT) in the pharmaceutical industry is encouraged by the US FDA to ensure better product quality control and quicker time to market.

The MSR™ technology has embraced the PAT initiative as it allows drug manufacturers to complete real-time monitoring of their microsphere product quality and integrity during various production stages such as filtration and drying processes (including lyophilisation).

The integration of PAT reduces the trial-and-error approach. This helps drug companies move towards right-first-time manufacturing and reduces drug development times for microspheres – traditionally more demanding than regular drugs.

Scientists in Laboratory

Developing complex drug formulations such as microsphere delivery systems has traditionally been challenging for most drug manufacturers, big or small. Ensuring that the chosen process technology used at R&D stage can be fully scalable to larger production batches is crucial. Finding out too late that a microsphere process is not scalable can have devastating impact and cost millions of dollars to drug manufacturers. The MSR™ product range was designed to simplify the scale-up development of microsphere drugs, from early R&D activities to GLP batches and then from clinical trials to commercial production. Our solutions can ensure that key process objectives (such as product yield, product quality and integrity, batch consistency, etc.) and key production parameters (such as filtration time, washing time, drying time, etc.) can be maintained at every scale.
