Reliable sterile filtration for the most difficult solutions

Todays ophthalmic prescriptive drugs and lens care solutions have a wide variety of additives to enhance the user experience with respect to comfort and efficacy. These additives can play havoc with filtration systems and reduce efficiencies in production if not properly designed. We can help you implement an optimised system to guarantee sterility of your final product while maximising throughputs and reducing processing times.

Not able to repeatedly process full batches of product

Not able to repeatedly process full batches of product?

Cellulose based additives such as HPMC and CMC can have variable in the quality of the raw materials. This variability can cause problems with the mixing step and problems such as undissolved or part dissolved components can occur. Sometimes the filtration step can actually cause further precipitation of the cellulose based solution. Careful design and selection of the filtration system can help to eliminate these problems as provide trouble free processing of the batch.

Suffering product loss through low percentage preservative at final fill?

Below specification concentration of preservatives such as BAK and PHMB can be caused by the adsorption preservative on the filtration membrane. This can be mitigated by flowing to drain until the required specification is reached or recirculating to fully saturate the membrane with preservative. Getting the filtration stage designed correctly at the beginning can shorten your time to market as well as maximising product margins

Is cost per litre your driver

Is cost per litre your driver?

If you are manufacturing a simple lens care solution for packaging that is relatively easy to filter you will want to concentrate on trying to minimise your production costs. Solutions without complex comfort agents that mainly contain preservatives can be sized at much higher flux rates without affecting the quality of the final product. Using a filter with a high flux rate membrane and low preservative binding characteristics can effectively reduce your cost per litre, facilitating an increase number of processed batches per day

CASE STUDY

Alternative filter systems for saline production

Alternative filter systems for saline production

Application

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.

The solution

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.

Reducing risk and improving lead- times in monomer production

Reducing risk and improving lead- times in monomer production

Application

Monomer production is a critical part of the production process and previously a competitors pleated polypropylene capsule filters, rated at 1.2μm, 2.5μm and 5μm had been used.

The filters are important in ensuring the monomer is free of any impurities before being used in the lens manufacturing process.

The solution

Amazon Filters carried out an extensive technical review of the process and offered a like for like capsule from its SupaPore PCG Capsule range. The Amazon capsules were subjected to a rigorous validation process which involved testing to demonstrate equivalence to the previous capsules and to ensure the change did not impact on the filtration time which is critical for this batch process.

Benefits

Improved lead times and greater security of supply has reduced the potential risks to the manufacturer's monomer production. In addition to the cost savings achieved by switching supplier, Amazon Filters also add value to the process by offering local and readily available support. This gives them direct and immediate contact with their filter supplier which is crucial on such a critical system.
