Download:These validated 0.2 micron-rated sterilizing grade filters retain Brevundimonas diminuta (ATCC 19146) at 107 CFU/cm² effective filter area (EFA) and ensure very low extractables and adsorption. They are recommended for sterilizing filtration of pharmaceutical fluids including solutions with active ingredients, biologicals, biotech proteins, ophthalmics and other dilute preservative solutions.
Kleenpak capsules are rugged and compact, can be supplied with a broad range of filter media, and can be offered in up to four different filter area sizes designed for a variety of applications in pharmaceutical manufacturing environments (volumes of 30 L to 1000 L) from small to large-scale. These in-line single-use assemblies are available with sanitary or hose barb inlet/outlet fittings.
