Pure PES membrane

Sartoguard PES

For all, basic membrane prefiltration steps to protect your final membrane filter and downstream equipment. The single-use variants are also available as gamma sterilizable versions.

Power of glass fleece

Sartoguard GF

The Sartoguard GF filter elements combining the defined retention performance of membrane filters with high adsorptive power of glass fiber fleeces.

Unique PES Nanofleece

Sartoguard NF

The Sartoguard NF is the only gamma sterilizable membrane depth filter combination in single-use applications utilizing unique PES Nanofleece technology. The Nanofleece protects the membrane double layer from early blockage due to a high particle load.

For highest process flexibility all Sartoguard® filters are available as for conventional stainless steel or single use applications. All filter elements are available in various sizes and adapter combinations.
