Designed for efficient sample preparation, this syringe filter features a 4 mm diameter and a 0.45 micron pore size, making it ideal for rapid filtration of small-volume samples in analytical and laboratory settings. The polypropylene housing ensures excellent chemical compatibility and mechanical strength, while the hydrophobic PTFE membrane enables reliable filtration of aggressive solvents, harsh chemicals, and aqueous-organic mixtures. Frequently used prior to chromatography or mass spectrometry analyses, these filters help protect instrument columns and detectors by preventing particulate contamination.

Each pack contains 100 single-use units, supporting workflows in pharmaceutical development, environmental testing, food safety, and clinical research. The low protein binding of the PTFE membrane helps maximize sample recovery, which is essential for trace analysis and quantification assays. Compatible with a wide range of solvents and sample types, the design supports applications in HPLC, UHPLC, and GC systems, as well as sample clarification before spectrophotometric and ion chromatography measurements. This product integrates seamlessly with manual and automated syringe and autosampler setups, providing consistent, reproducible results. For broader filtration needs, consider other membrane materials, pore sizes, or diameters available within the Captiva Premium Syringe Filter portfolio.
