Micro-Media - Filter Pad
The addition of filter aids and wet strength resin differentiates the Micro-Media Series from the Alpha-Media Series. But that is not where the differences end. The addition of these ingredients improves retention efficiencies by adding internal surface area and the positive charge known as Zeta-Potential. Zeta-Potential is the positively charged site within the matrix of fibers and filter aid which attracts negatively charged particles which may be smaller than the pore sizes available in the filter pad.
Wet strength resins are capable of being steam sterilized and are all free of formaldehyde. Filter aids used are Perlite and/or Diatomaceous Earth which also help to improve filtration efficiencies. Grades include: M-05, M-054, M-10, M-104, M-40, M-404, M-45, M-454, M-50, M-504, M-504T, M-70, M-704, M-85, M-854, and M-90.
The Right Choice for Critical Processing
Micro-Media Series Depth Filter Media, formulated with cellulose, wet strength resin and diatomite and/or perlite is specifically designed for use in critical applications. All components of ErtelAlsop Micro-Media are listed in the CFR as generally recognized as safe for contact with food as dictated by 21CFR 176.170.
Composition
ErtelAlsop Micro-Media filter sheets are composed of cellulose pulp, Diatomaceous Earth and/or Perlite and a wet strength resin, which charge modifies 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.

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
All ErtelAlsop media formulations can be manufactured in formats to fit your application. Filter sheets, discs and Pak Lenticular Cartridges are all available to provide you with product to optimize your application. ErtelAlsop also manufactures a complete line of filter machinery, from Small Batch and Pilot Scale Lab Filters to Plate and Frame Filters, Sealed Disc Filters and Pak Lenticular Cartridge Housings.
For over 80 years, ErtelAlsop has been proactively solving the depth filtration problems of industry. We originated and patented the Pak Lenticular Cartridge concept. We created the BioClean™ Sanitary Filter Plate Assembly to accommodate the stringent cleaning standards of the pharmaceutical industry. Most recently, we took the traditional plate and frame concept and literally turned it on its ear. The Diamond Series™ line of Plate and Frame Filter Presses combines weld-free technology for the ultimate in cleanliness with a diamond shape, which allows for complete drainage and venting.
The most accurate way to optimize your process is through laboratory scale testing. Samples of Micro-Media, Micro-Media XL Series, or Micro-Clear Media 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.
