Wet-strengthened filters for vacuum filtration

For many vacuum filtration applications, a thin filter paper with a slow flow rate and excellent wet strength can maintain sample quality and purity. Because Grade 50 thin filter papers are hardened to minimize fiber shredding, they are a good choice for use as carriers in integrated circuits.

Grade 50 thin filter paper from GE Healthcares Life Sciences business is very strong when wet. It will withstand wet handling and precipitate removal by scraping.

Grade 50 is also available in Smear Tab format for wipe testing (e.g., testing of surfaces for radionuclide contamination).
