PTFE Membrane, TE Range (TE 36), 0.45um Pore Size, 25mm Circle (50 pcs) SKU: 10411305

PTFE Membrane Filters - 10411305

Engineered for high retention efficiency and superior chemical stability, the Whatman 10411305 achieves reliable separation results across a broad range of analytical and preparative applications. Supporting this capability, quality-controlled manufacturing ensures the filtration medium delivers the retention efficiency and throughput that demanding laboratory protocols require. On this basis, controlled production conditions produce membranes with documented pore size distribution and thickness tolerances, supporting method reproducibility across multiple filter lots.

Material Specifications

Bulk packaging format provides cost-effective access for high-volume laboratories performing non-critical filtration and sample preparation.
Near-zero extractable levels ensure PTFE membranes contribute no measurable background to mass spectrometry or trace analytical workflows.
Unmatched solvent resistance allows PTFE to process chlorinated hydrocarbons, ketones, and strong oxidizers that destroy other membrane chemistries.
Permanently hydrophobic and chemically inert, PTFE resists degradation from virtually every solvent, acid, and base encountered in laboratory applications.
Excellent for filtering aggressive acids, bases, and non-aqueous solvents.

Reproducible particle counting and size distribution analysis start with a membrane surface that captures particles uniformly — the pore consistency documented above ensures your counts reflect the sample, not random variation in the filter. Under these conditions, universal chemical resistance makes PTFE the membrane you reach for when your sample matrix would dissolve any other filter medium — strong acids, aggressive solvents, and oxidizers pass through without affecting integrity. Secure your research outcomes by partnering with a filtration solution that understands your need for speed, accuracy, and reproducibility.
