Alternative filter systems for saline production
Saline is used within ophthalmic manufacturing and is supplied by transferring the saline from mixing vats into moveable saline containers which are then used throughout the process. The Saline is filtered using 0.2 micron dual layer membrane filters to provide protection against contamination from debris and microorganisms. Previously, capsule filters were used and these were flushed, autoclaved and integrity tested between batches.
Noting the capsules used were not suitable for autoclaving and repeated re-use, Amazon suggested converting the capsules to cartridge filters.
Amazon was able to offer a bespoke design of a filter trolley system which integrated a 72 Series housing and SupaPore VP membrane cartridge filter.
Working in conjunction with the ophthalmic manufacturer, new work procedures and a system commission programme were introduced to prove and validate the new filter system.
