#### Sector

Healthcare

## Background

Amazon Filters is one of Europe’s leading process filter manufacturers and prides itself on providing a high level of technical and logistical support to its customer base. We identified an application to offer alternative filter systems to those traditionally used by one ophthalmic manufacturer for its saline production processes.

As well as targeting cost savings, we identified that its existing [capsule filter](https://www.amazonfilters.com/products/filter-cartridges-and-capsules/capsule-filters) wasn't fit for application purpose, specifically in regards to autoclaving and re-using.

## Application 

Ophthalmic manufacturers use saline throughout the manufacturing process, which they obtain by transferring the saline from mixing vats into moveable saline containers.

The Saline is filtered using 0.2 micron dual layer [membrane filters](https://www.amazonfilters.com/products/filter-cartridges-and-capsules/membrane-filters) to provide protection against contamination from debris and microorganisms.

Previously, the manufacturer used capsule filters were which they flushed, autoclaved, and integrity tested between batches.

![Diagram of a filter](https://www.amazonfilters.com/hubfs/image-png-Dec-08-2022-01-26-08-4029-PM.png)

## Solutions

Noting the capsules weren't suitable for autoclaving and repeated re-use, we suggested converting the capsules to [cartridge filters](https://www.amazonfilters.com/products/filter-cartridges-and-capsules).

We offered a bespoke design of a filter trolley system which integrated a [72 Series](https://www.amazonfilters.com/products/filter-housings/sanitary-housings/72-series) housing and [SupaPore VPBA](https://www.amazonfilters.com/products/filter-cartridges-and-capsules/membrane-filters/supapore-vp-biological-filters) membrane cartridge filter. Working in conjunction with the ophthalmic manufacturer, we introduced new work procedures and a system commission programme to prove and validate the new filter system.

## Benefits

The Amazon [pharmaceutical filtration system](https://www.amazonfilters.com/industry/pharmaceutical-filters) provides huge cost savings, as the previous capsule could only be autoclaved 3 times (max). By contrast, our filter can be autoclaved 20 times, reducing operational costs by a factor of >4.

This also meant less stock-holding and less waste from used filters. In addition, the lightweight portable trolley system has made processing saline much easier, cleaner, and safer, as operators can move and adjust the trolley height easily as required. Consolidated use of the filter cartridge across multiple applications provided additional benefits.
