Micro-Media - Model XL Series - Filter Pads
From Filter Sheets
Micro-Media XL Series Depth Filter Media, formulated with cellulose, wet strength resin and Celpure diatomite, an ultra-pure form of Diatomaceous Earth manufactured only by Advanced Minerals Corporation, is specifically designed for use in critical applications. DE can now meet the high quality standards dictated by 21CFR211.160 (b). Traditional “food-grade” forms of DE rarely meet USP-NF standards.
Most filter media manufacturers currently use DE formed to “food-grade” quality standards, NOT pharmaceutical component quality standards, which allows for problems with respect to compendial standards, purity, manufacturing and process control and packaging.
Because the majority of diatomite producers send more than 90% of their products into industrial and food-grade applications, “food-grade” DE is produced to commodity-type standards and economics, which means product specification testing is performed as little as every 10,000 kg of production volume. Unchecked variations in diatomite result in significant process deviation such as filtrate color, pH and impurity profiles.
ErtelAlsop Micro-Media filter sheets are composed of cellulose pulp, Celpure Diatomaceous Earth and wet strength resin, which causes the media to exhibit a net positive charge zeta potential. This allows for the highly efficient removal of particles smaller than the filter’s nominal rating. The Micro-Clear carbon impregnated line of media can also be manufactured using Celpure diatomite.

Product testing is always available either at your facility, through our network of distributors, or at our in-house laboratory.
Pilot Testing - Rentals
For in-plant testing and scale-up procedures, ErtelAlsop offers a variety of lab filters for rent. A portion of rental fees can be applied to the purchase of your full production filter.
The most accurate way to optimize your process is through laboratory scale testing. Samples of Micro-Media XL are available at no charge. Authorized ErtelAlsop representatives are equipped to run trials on-site, or product samples may be sent directly to ErtelAlsop for testing with prior approval.
