SANIpore® DS

Final Sterilizing Filter Elements

SANIpore® DS Filter Cartridges have been established as a new generation of PES membranes in sterile-grade filtration. The unique double-layer PES membrane design not only provides excellent microbial retention but is also cost-effective.

SANIpore® DS filter cartridges are frequently sterilized with steam or hot water to extend service life and reduce replacement costs.

Polyethersulfone is particularly suited for the filtration of products that contain substances that adsorb to the media. The lower binding characteristics of PES make it a good choice for the filtration of valuable protein solutions such as vaccines and biologicals.

Common questions about Sanitek

Common Questions about SanitekWhat is the asymmetric PES?

The size of the apertures changes along the membrane’s thickness, with the greatest openings appearing on one side and the smallest openings on the other. Each side of the membrane appears slightly different when viewed with reflected light at low incidence angles. In comparison to the side with the smallest pores, the side with the greatest pores will appear more matte or dull (which will appear shinier).

The majority of people can quickly distinguish the sides if they have some experience. Without effecting retention, the membranes can be utilized with either surface pointed upstream. However, pointing the bright side upstream enables more accurate examinations of the retained particles while orienting the dull side upstream boosts overall throughput.

Common Questions about SanitekHow do you assure the quality of your products?

At Sanitek, we pay attention to the details of every link and strictly adhere to ISO 9001:2008 and ISO 13485:2005 standards to ensure the quality of our products.
