Acro Disc Premium SyRing Filter, Glass Fiber 92 Grade, 1.0um Retention Rating, 1000/Pk
Pall SKU: AP-4142

Pall Acrodisc Glass Fiber (GF) Syringe Filters, 1 µm, 25 mm - AP-4142

Quality controls spanning raw membrane casting through final device integrity testing ensure consistent performance across Pall production lots. A syringe filter holds its membrane in a leak-tight housing for clarification at the bench. The glass microfiber matrix delivers nominal retention as a depth medium and offers broad chemical compatibility. The polypropylene housing routes flow to minimize backpressure in service while holding extractables low for sensitive analyses and prevents sample bypass under rated operating pressure. When chromatographic methods demand particle-free injections, point-of-use syringe filtration clarifies the sample before it reaches the column.

Technical Specifications

• Biologically inert borosilicate fiber with broad chemical compatibility
• Naturally hydrophilic surface wets rapidly with aqueous samples
• Nominal depth retention with high dirt-loading capacity
• Withstands high-temperature pre-conditioning up to 500°C
• Inorganic construction suits demanding sample-preparation chemistries

Housing Specifications

• Medical-grade polypropylene with broad chemical compatibility
• Thermal-bonded construction keeps adhesives out of the fluid path
• Stable across the full aqueous pH range in routine sample work
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate

Removing particulates from your buffers and mobile phases extends column life and keeps your baselines steady. Upstream buffer clarification keeps avoidable particulates out of your flow path across routine and validated analytical methods.
