Tisch
PES Membrane Filter, 5.0um, 47mm, Nonsterile, 200 Pk SKU: SF18120

Polyethersulfone (PES) Membrane Filters - SF18120

Designed to deliver reproducibility and confidence across critical sample types, the Tisch SF18120 provides the filtration consistency that method validation demands. At its core, quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. Consistent surface properties across the full membrane area support uniform particle capture and reliable results in gravimetric, microscopic, and culture-based analytical workflows.

Material Specifications

• Materials of construction maintain their mechanical and chemical properties at temperatures up to 60°C, supporting heated filtration protocols.
• Inherent hydrophobicity resists wetting by aqueous solutions, making the membrane suited for gas-phase applications and non-aqueous solvent filtration.
• Naturally hydrophilic, PES membranes require no pre-wetting and offer broad compatibility with aqueous buffers, alcohols, and mild organic solvents.
• Minimal background interference from extractables ensures PES membranes protect the integrity of sensitive biological preparations during filtration.
• Engineered for rapid throughput, PES provides an asymmetric pore structure that resists premature clogging during high-volume filtration runs.

Maintaining accreditation under ISO 17025 or similar quality frameworks requires documented traceability at every step — the specification compliance of each membrane lot supports your ongoing audit readiness. Thermal stability allows you to autoclave and reuse membrane holders without replacing the filter medium, reducing consumable costs in high-throughput workflows. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.

Wettability

Hydrophobic

• Enzyme Recovery - Ensures minimal yield loss during the filtration of dilute enzyme solutions due to its inherently low-binding surface.
• Bioreactor Sampling - Integrated into sampling ports to allow fluid withdrawal from bioreactors without compromising the vessel environment.
• Buffer Batching - Clarifies large batches of biological buffers in production, protecting downstream chromatography columns from fouling.
• Microarray Substrate - Provides a low-background surface for protein array printing, minimizing noise in high-throughput screening applications.
• 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.
