It is recognised that optimising the chemical compatibility of solvent filters while maintaining low consumable cost is a significant concern for pharmaceutical process engineers
In processing aggressive solvents, filter cartridges manufactured from materials like PTFE are often chosen for their wide compatibility with these chemicals. This ensures effective filtration without the concern of cartridge degradation
The problem with this approach is that filter cartridges made from these materials are expensive, often so expensive that they will not be applied to less aggressive duties. These are usually filtered using lower cost, but lower compatibility, filter media such as polypropylene
This leads to a situation where multiple media types are used throughout the process, thereby introducing complexity while causing difficulties for operations, process engineering and even procurement.
Amazon Filters have resolved this dilemma with the introduction of SupaPore Halar – high compatibility, pleated filter cartridges. SupaPore Halar filters are constructed using Halar fluoropolymer offering a unique combination of mechanical properties and thermal and chemical resistance. SupaPore Halar offers greater compatibility than polypropylene media filters at a cost that is typically lower than PTFE membrane cartridges. This approach may allow a process engineer to select a single, high compatibility but lower cost filter cartridge to apply throughout the process.
