General description

Milligard® PES 1.2/0.2 μm nominal filters are designed for effective bioburden control and reliable particulate removal from a broad range of fluid streams. When used standalone for non critical applications, these membrane-based filters typically remove Ͱ 6 log Brevundimonas diminuta. When used upstream of sterilizing-grade filters or other unit operations, they improve processing efficiency.
Milligard® PES filters are supported by the Emprove® Program which consolidates product specific testing, quality and regulatory information to simplify compliance needs.
