Hot-Selling High Quality 47/55/70/90/110/125/150mm Fast Speed Laboratory Qualitative Whatman Filter Paper

Product Description:

  Fast-flowing ashless filter paper is recommended for analytical processes such as aluminium hydroxide or ferric hydroxide. It is also used for filtration of large particles or gelatinous precipitates, such as iron content in iron ores and magnesium content in magnesium ores. It is also used for the determination of ambient air pollutants, such as suspended particulates, gaseous compounds (such as fluoride), etc., or filtration of digestion solutions for spectroscopic, chromatographic or mass spectrometric analysis, such as picric acid turbidity, pectic acid in foods and other determinations.

Features:

  The retention of fine particles is good, the flow rate is fast, and the load capacity is high. It can be used for high-efficiency filtration in laboratories, such as wastewater filtration in industrial wastewater monitoring, algae and bacterial culture, food analysis, protein filtration and weak β-ray radioimmunoassay. It is recommended to be used for the gravimetric determination of air particles, flue gas sampling and adsorption monitoring methods for air pollution.
  Whatman GF/A cassette filter membrane is used for static sampling and individual air samplers. These aerosol sampling membranes and particle monitoring filter membranes are characterized by high flow rates and low sample interference.
