Product Description
Filter paper Grade: 50, 125 mm
  • Thinner filter design (average thickness of 115 micro-m) than most Buchner filter papers
  • Acid-treated for high wet-strength and chemical resistance
  • Nominal particle retention of 2.7 micro-m
  • Slow flow rates (Herzberg filtration speed 2685 s)
  • High purity and low ash content (0.015% ash maximum)
  • Compatible with Hirsch or Buchner funnels

GE offers three grades of hardened low ash filters. All three are designed for use in Hirsch and Buchner funnel applications and can be customized for an exact fit.
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).

Looking for a filter paper, membrane filter, or syringe filter? Let GE help you find the optimal filter for your needs to ensure reliable analysis.
