Grade 50 Filter Papers by Whatman

  • Hardened low ash: 0.015% ash maximum
  • These filters are treated with a strong acid to remove trace metals and produce high wet strength and chemical resistance
  • These are particularly suitable for Büchner filtration where the tough smooth surface of the filter makes it easy to recover precipitates
  • The maximum ash content of these grades is intermediate between ashless and qualitative grades
  • They are particularly suitable for Büchner filtrations where it is desirable to recover the precipitate from the filter surface after filtration
  • Other characteristics include high wet strength and chemical resistance, which are similar to those of the acid-hardened ashless filter papers
  • Retention of very fine crystalline precipitates
  • The thinnest of all Whatman filter papers
  • Slow flow rate
  • Hardened and highly glazed surface
  • This finish also keeps the paper free from loose surface fibers
  • Highly suitable for qualitative or quantitative filtrations requiring vacuum assistance on Büchner or three-piece filter funnels
  • Very strong when wet. Will withstand wet handling and precipitate removal by scraping. In the electronics industry, the virtual absence of fiber shedding is utilized in carriers for integrated circuits
  • This grade is also available in Smear Tab format for wipe testing (e.g., testing of surfaces for radionuclide contamination)
