Sterile Acro Disc WBC Syringe Filters w/ Leukosorb Membrane, 10/Pk
Pall SKU: AP-4951

Pall Acrodisc Leukosorb Syringe Filters, Nominal Retention, 25 mm, 10/Pk - AP-4951

Quality controls across fiber web formation and finished device testing support consistent capture performance across Pall lots. At the bench, a leukocyte-capture syringe filter retains white cells while the filtrate passes through to collection. The fiber matrix combines size-based retention with surface adsorption while letting red cells and platelets travel onward and achieves leukocyte reduction in a single forward pass. Polypropylene construction resists chemical degradation from routine sample matrices while holding a reliable seal against the membrane edge and holds extractables low for sensitive analyses. For studies working from limited blood volumes, single-pass separation preserves both the retained cells and the filtrate.

Technical Specifications

• Red blood cells and platelets deform and pass into the filtrate
• Leukocyte reduction of whole blood samples in a single forward pass
• Hydrophilic fiber surface wets directly with whole blood
• Fiber surface tuned for surface charge and critical wetting surface tension
• Multimodal fiber matrix captures leukocytes by size retention and adsorption

Housing Specifications

• Resists stress cracking from aqueous salt and buffer solutions
• Plasticizer-free polyolefin construction keeps the fluid path clean
• Reliable housing-to-membrane seal prevents bypass at rated pressure
• Tough polypropylene body tolerates repeated handling at the bench

When you are working from a limited blood draw, the separation step has to succeed the first time. Selective leukocyte separation keeps both of your blood fractions usable across genomic, immunophenotyping, and cell-analysis workflows. Ask our friendly customer service team to confirm the pore size, membrane, and sterility options your filtration application calls for.

• Genetic Screening - Provides a clean WBC sample for high-quality genomic DNA isolation to support accurate and reliable diagnostic testing
• Stem Cell Research - Isolates specific cell populations gently and efficiently for culture or analysis to maintain cell viability and function
• Leuko-depletion - Removes white blood cells from blood samples for transfusion research studies to prepare pure plasma or RBC fractions
• WBC Isolation - Separates white blood cells from whole blood without complex density gradient centrifugation to simplify laboratory workflows
• DNA/RNA Extraction - Recovers leukocytes for downstream genetic analysis and PCR workflows, ensuring high-quality input material for sequencing
• Bedside Prep - Facilitates rapid leukocyte capture in point-of-care or field settings where centrifugation equipment is not readily available
