We Can Support With Your Membrane Filtration Requirements
Membrane Selection
We can offer a wide range of membranes with different characteristics. We can help you select the most appropriate membrane for your gas/venting or liquid filtration application and support with characterizing the membrane for bacterial/endotoxin challenge, bubble point, chemical compatibility, water intrusion, etc. We can offer membranes for diagnostic applications and advice on optimizing our materials for your assay, helping you troubleshoot any issues you may encounter during your development process
Device Integrity Testing
Once you have incorporated our membrane into your device, you will want to know if it is integral. Our Scientists can perform this testing for you.
Protein Binding
Different applications require different levels of protein binding. Point of care diagnostic devices will typically require high levels whereas intravenous (IV) filtration devices will need low levels. We can perform testing of this property on flat sheet media or finished devices.
Bacterial Retention
Bacterial challenge studies may be necessary to provide documented evidence of a filter’s capability to remove inadvertent bacterial contamination. Pall Medical typically use a method based on the industry standard ASTM F838-20 ”Standard test method for determining bacterial retention of membrane filters utilized for liquid filtration” using Brevundimonas diminuta (ATCC 19146). Other micro-organisms can also be utilized and tests can be performed using a modal system or a specified fluid, in which case protocols are developed in consultation with the client. These may include, for example, special consideration for drug formulation and filter compatibility.
