Tisch SKU: SF17400

Tisch Scientific PTFE Syringe Filters, 5 µm, 25 mm, 100/Pk - SF17400

Tisch Scientific's sales team brings fast, courteous service to every filtration order, from first quote through fulfillment. Syringe filters span a wide range of membrane chemistries and pore sizes, so the format can be matched to the sample matrix and solvent system in use. Chemically inert PTFE resists attack from the harshest process chemistries while clarifying solvent streams at the rated pore size and suits solvent filtration where other membranes fail. The polypropylene housing resists aqueous acids, bases, and alcohols in routine use and delivers a chemically clean filtrate to the downstream step. Where bench-scale prep must move quickly from one sample to the next, each sample starts as clean as the last without a carry-over risk or a cleaning step between uses.

Membrane Characteristics

• Minimal moisture absorption pairs with a low tare mass
• Non-fibrous, fully synthetic structure sheds no fibers into filtrate
• Insolubility in all known organic solvents avoids swelling and pore distortion
• Hydrofluoric acid resistance holds even in fully acid-digested samples
• Strong oxidizing agents like nascent chlorine and concentrated sodium hydroxide cause no attack

Housing Characteristics

• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream
• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
• Impact-tolerant polypropylene body withstands routine bench handling without damage

A filter that softens or swells in your solvent fails you mid-run, batch after batch. Solvent-stream filtration handles the solvents and reagents your methods rely on across the organic solvents and harsh reagents your methods use.

• Extractables Testing - Clarifies packaging material organic solvent extracts ahead of LC-MS analysis, keeping background low for leachable detection.
• Spirits Congener Analysis - Clarifies distilled spirits samples ahead of GC analysis, protecting columns from residue during congener profiling.
• Dissolution Testing - Stops the dissolution reaction and clarifies samples, with low API binding for accurate potency quantitation.
• Battery Electrolyte Prep - Clarifies lithium-ion battery electrolyte in carbonate solvents ahead of GC-MS purity and impurity analysis.
• Aggressive Solvents - Clarifies chlorinated hydrocarbons and aromatics without membrane degradation, delivering pure filtrate quality consistently.
• Trace Metals Analysis - PTFE's low metal-extractable profile clarifies acid-digested samples for clean, low-background ICP-MS and ICP-OES results.
