Disc Filter Membrane

Each Disc Filter Membrane is precision-cut into standardized, ready-to-use circular shapes (common diameters: 25mm, 47mm, 90mm, etc.), designed for direct integration with laboratory filter funnels, syringe filters, and small-scale filtration setups. Its rigid yet lightweight structure ensures easy handling and secure placement, eliminating leakage risks during batch operations. Ideal for R&D labs, quality control tests, and small-batch production, this format allows for quick filter replacement and minimal cross-contamination. With consistent pore size distribution across every disc, it delivers reliable, reproducible results for particle analysis, sample purification, and sterile filtration of small solution volumes—perfect for industries requiring frequent, low-volume filtration with high accuracy.
