Argonide introduces NanoCeram® Electropositive Filters - A major advance in laboratory separation and biotechnology. Capable
of retaining >5 logs (99.999+ %) viral and bacteria particles at water flow rates more than 200 times greater than ultraporous filters.
The active ingredient of NanoCeram® filters is an alumina fiber only 2 nm in diameter. The 0.7 mm
thick filters are highly electropositive in water and attract and retain viral and bacterial microbes, endotoxins, DNA, RNA, electro-negatively
charged proteins as well as sub-micron and nanosize organic and inorganic particles. Ultra-fine particles are collected within the filter rather
than on its surface. This results in high capacity, less clogging, and with minimal pressure drop. NanoCeram® filters are capable of
longer life, even in the presence of saline solutions. They function best between pH 5 and 9.

RETENTION - Viral (MS-2) retention is 99.7% for one layer and 5-6 logs for two layers
thick. Bacteria (K terrigena and E coli) ~ 6 logs for one layer. Microbes or proteins may be desorbable at
higher pH's, with EDTA or beef extract. THROUGHPUT
(clogging resistance) - Ten fold or greater than ultraporous filters.
