Diagnostic Membranes
Membranes for In Vitro Diagnostics, Microarray & OEM
Being the first industrial manufacturer of membranes, Sartorius Stedim Biotech has developed an unmatched expertise in the production of various microporous membranes. Our exceptional broad variety of OEM membranes allows you to select the membrane with the best performance characteristics for your device. While nitrocellulose membranes are ideally suited for all protein assays, polyethersulfone (PES) membranes are setting new standards in liquid and gas filtration applications including medical devices.

Consistency Matters for Rapid Tests
Unisart® Lateral Flow Membranes provide intra-and-inter lot consistency for diagnostic lateral test manufacturers.

Get Sharp and Intense Lines on Your Blot
Unisart® Nitrocellulose Membranes are the best substrate to spot or line dispense your recombinant proteins.

Smart Multiplex Strip Design
UniSart StructSure® for Multiparameter Assays enable the design of new multiplex tests with compact and easy to assemble lateral flow format.

Let Your Protein Spots Shine on Nitrocellulose
Unisart® Microarray Slides enlighten your thousands of protein spots and fulfill the needs of massive multiplex assays.

Liquid Filtration
High Efficiency PES Membranes provide high flow rates with an excellent throughput and very low non-specific adsorption characteristics.
Venting & Gas Filtration
Gamma Compatible PES Membranes for fast air filtration combine exceptionally high flow rates with reliable liquid retention properties.
