Opthalmics
Look to Amazon for safe, sterile production of ophthalmic solutions.
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?
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?
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
Total Flexibility
We are able to work with cartridges and housings from all major manufactures giving you complete flexibility.

CASE STUDY
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.
