Pall
Acro Disc Syringe Filters w/ Nylon Membrane - DMSO-Safe - 0.2um, 25mm, Sterile, 50/Pk SKU: 4433

Pall AcroDisc 4433 syringe filters with nylon membrane deliver superior filtration performance for critical laboratory applications requiring reliable particulate removal and sample clarification. These premium 0.2 micron syringe filters are specifically engineered to provide consistent, high-quality results while maintaining sample integrity throughout the filtration process. Designed for demanding research environments, these sterile syringe filters offer exceptional chemical compatibility and robust construction that laboratory professionals can depend on for their most sensitive analytical procedures.

The advanced nylon membrane technology provides excellent particle retention efficiency at the 0.2 micron pore size, ensuring effective removal of bacteria, precipitates, and other contaminants while maintaining optimal flow rates. The hydrophilic nylon syringe filters offer broad chemical compatibility, including full DMSO safe certification, making these laboratory filters ideal for pharmaceutical, biotechnology, and analytical chemistry applications. The membrane's inherent low protein binding characteristics help preserve sample composition and minimize analyte loss during filtration, critical for maintaining data accuracy in quantitative analyses and laboratory research.

These versatile laboratory syringe filters excel in sample preparation for HPLC sample prep, GC analysis, ion chromatography, and spectrophotometric analysis, particularly when working with organic solvents, buffer solutions, and protein-containing samples. The DMSO-safe syringe filters ensure reliable performance with dimethyl sulfoxide and other aggressive solvents commonly used in drug discovery and chemical synthesis workflows. The sterile filters are equally effective for clarifying cell culture media, removing particulates from biological samples, and preparing solutions for microbiological testing where sterility maintenance is paramount for laboratory applications.

Each nylon membrane filter features excellent filtration area, a compact design, and a robust polypropylene housing that withstands typical laboratory pressures without compromising membrane integrity. The sterile syringe filter packaging ensures immediate use in aseptic applications without additional sterilization steps, streamlining laboratory protocols and reducing contamination risks. The ergonomic design facilitates easy handling and secure syringe connection, minimizing the potential for leaks or sample loss during filtration procedures in research laboratories.

The universal luer-lock connections ensure secure attachment to most syringe types, while the low hold-up volume design maximizes sample recovery. The consistent manufacturing quality and rigorous quality control testing guarantee batch-to-batch reproducibility, essential for maintaining analytical method validation and regulatory compliance.

The Pall AcroDisc 4433 syringe filters represent an optimal balance of performance, reliability, and value. The combination of superior nylon membrane technology, comprehensive chemical compatibility, and sterile convenience packaging makes these filters an essential component for advancing research outcomes where sample purity and analytical accuracy are non-negotiable requirements.
