Sartoguard GF Midicaps®
All members of the Sartoguard family utilize a highly asymmetric polyether sulfone (PES) membrane double layer for unmatched protection of final filters and bioburden reduction with an LRV of 6 per cm². In addition, combinations with different depth filter materials and gamma sterilizable versions are available.

- Significantly higher total throughput performance
- LRV of 6 per cm2 filtration area for Brevundimonas Diminuta and for Serratia Marcescens
Pure PES membrane
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
The Sartoguard GF filter elements combining the defined retention performance of membrane filters with high adsorptive power of glass fiber fleeces.
Unique PES Nanofleece
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.

The Sartopure® filter family is optimized for the clarification and retention by utilizing multiple layers of progressively finer pleated polypropylene or adsorptive glass fleece material. The turbidity reduction results in optimal protection of all downstream material like chromatographic columns or membrane filters.
