SKR
SKR filter cartridges are pleated, small-area filters for critical point-of-use filtration and small batch processing of liquids and gases.
Available in two sizes, the filters are designed for use in Meissner’s SKR filter housings and in competitive filter housings that accommodate a skirt-flange sealing mechanism. SKR filter cartridges are part of Meissner’s SFE (Small Flow Element) filter product line.
A skirt-flange adapter is integrally welded to the end cap of each SKR filter cartridge. When the cartridge is installed and the housing is fully assembled, the adapter prevents fluid bypass.

What specifications or sizes are available for SKR Filters?
Specific size and specification details for SKR Filters are not provided in the current documentation. Typically, small filter cartridges like SKR Filters are available in various micron ratings and lengths to accommodate different flow rates and filtration requirements. For exact specifications, consult technical datasheets or contact the manufacturer directly.
What makes SKR Filters unique?
SKR Filters are distinguished by their suitability for critical point-of-use and small batch applications, supporting both liquid and gas filtration. Their design focuses on ensuring high-quality filtration performance in compact form factors, enabling integration into small-scale or specialized bioprocess workflows.
How do SKR Filters integrate with other systems?
SKR Filters integrate into bioprocess systems at the point-of-use stage, typically installed inline within fluid or gas transfer lines. Their compact cartridge design allows for easy connection with standard sanitary fittings and compatibility with single-use or reusable systems, facilitating seamless incorporation into existing process setups.
Are SKR Filters suitable for regulated biopharmaceutical manufacturing?
Yes, SKR Filters are suitable for regulated biopharmaceutical manufacturing environments. They are designed to meet the stringent requirements of critical point-of-use filtration, ensuring product sterility and process compliance. However, users should verify specific regulatory certifications and validation documentation as applicable to their process.
Can SKR Filters be customized?
Customization options for SKR Filters are not explicitly detailed in the provided information. Typically, filter cartridges can be customized in terms of membrane material, pore size, and cartridge length to meet specific process needs. For customization inquiries, direct consultation with the manufacturer is recommended.
What other products are commonly used with SKR Filters?
SKR Filters are commonly used alongside upstream fluid handling and support equipment such as UltraClamp™ Sanitary Clamps and Universal Lab Stand. Downstream, they may be paired with process monitoring components like the SGT (Single-Use Gauge Tee). Additionally, support accessories such as the Stainless Steel Stand for FlexFill® Biocontainers are often used in conjunction with SKR Filters to facilitate handling and integration within bioprocess workflows.
