Acro Disc Syringe Filters w/ Nylon Membrane - 0.45um, 25mm, 200/Pk
Pall SKU: 4438

Pall Acrodisc Nylon Syringe Filters, 0.45 µm, 25 mm, 200/Pk - 4438

Quality controls spanning raw membrane casting through final device integrity testing ensure consistent performance across Pall production lots. A syringe filter seats a membrane in a sealed housing that threads onto a standard luer fitting. Nylon wets on contact with aqueous samples through its hydrophilic surface and supports high-volume routine filtration. The polypropylene housing resists aqueous acids, bases, and alcohols in routine use and maintains housing integrity through the filtration run. Where analytical results depend on clean samples, syringe filtration removes particulates at the moment of preparation.

Technical Specifications

• Alkaline-resistant across a broad range of aqueous buffers
• Low extractable contribution to sensitive analytical preparations
• Broad compatibility with alcohols, aliphatic, and aromatic solvents
• Non-sterile for routine clarification and sample prep
• Absolute pore size rating provides consistent results across filtration protocols

Housing Specifications

• Stable across the full aqueous pH range in routine sample work
• Rigid polypropylene body holds its shape under manual filtration pressure
• Resists aqueous acids, bases, and alcohols in routine sample prep
• Optimized internal geometry minimizes backpressure in service

Clarify your routine aqueous samples in a single pass and cut down on juggling multiple filter types at the bench. Consistent aqueous clarification keeps your sample preparation moving as a dependable step in your aqueous sample prep.
