The filtration of pharmaceutical and biological fluids requires a complete understanding of the filtration process, including both filter media and filter equipment. ErtelAlsop is the only US based manufacturer of a complete line of depth filtration products from sanitary laboratory equipment to sanitary production equipment, pharmaceutical grade filter paper and double O-ring plug-in style Pak® lenticular cartridges.

Cellulose based depth filter media provide a highly effective solution for clarifying or polishing pharmaceutical products such as  syrups, Large Volume Parenterals (LVPs), Small Volume Parenterals (SVPs), Active Pharmaceutical Ingredients (APIs), and biological products such as blood plasma, blood fractions, animal sera, fermentation broths, cell culture media and veterinary products. Depth filters are also widely used as a prefilter to final membrane filters. They are highly effective in minimizing the particulate challenge placed on the membrane, thereby providing ideal operating conditions to allow the membrane to realize its full potential.
