PES Membrane Filter, 0.8um, 47mm, Nonsterile, 100/Pk SKU: SF18090

Polyethersulfone (PES) Membrane Filters - SF18090

Designed to deliver reproducibility and confidence across critical sample types, the Tisch SF18090 provides the filtration consistency that method validation demands. Developed with critical workflows in mind, reproducible separation characteristics define the membrane structure, protecting downstream instruments and preserving sample integrity throughout the filtration process. For this reason, precision manufacturing ensures that each membrane disc delivers the rated retention, flow rate, and surface consistency that analytical and microbiological methods require.

Material Specifications

• Economical bulk packaging supports laboratories with high consumable throughput where individual sterile wrapping is unnecessary.
• Rigorous quality controls validate retention at rated pore sizes, positioning PES for critical pharmaceutical and biotechnology filtration.
• Asymmetric membrane architecture concentrates the retentive layer at the surface while maintaining an open substructure for sustained high flow.
• Polyethersulfone (PES) membranes deliver high flow rates with ultra-low protein binding, making them the preferred choice for biological sample filtration.
• Engineered for rapid throughput, PES provides an asymmetric pore structure that resists premature clogging during high-volume filtration runs.

Scaling from development to routine production requires membrane consistency at every lot, and the documented specifications provide the reproducibility needed to validate the filtration step once. Meeting this challenge, ultra-low protein binding ensures your biological filtrates retain the analyte concentrations present in the original sample, protecting yield in sensitive preparations. Take control of your sample preparation variables and ensure that your data reflects the true nature of your work, rather than the quality of your consumables.

Hydrophilic

• Tissue Culture Support - Acts as a porous growth support for 3D tissue culture inserts, allowing nutrient diffusion while anchoring the cells.
• Environmental Water Test - Recovers bacteria from water samples for culture analysis, ensuring high recovery rates due to uniform pore structure.
• Enzyme Recovery - Ensures minimal yield loss during the filtration of dilute enzyme solutions due to its inherently low-binding surface.
• Microarray Substrate - Provides a low-background surface for protein array printing, minimizing noise in high-throughput screening applications.
• Bioreactor Sampling - Integrated into sampling ports to allow fluid withdrawal from bioreactors without compromising the vessel environment.
• TFF Cassette Production - Used as the core membrane in flat-sheet tangential flow filtration devices for protein concentration and diafiltration.
