Our Filpaco line of filter papers have been trusted for quality, performance and value in the largest pharmaceutical companies for decades.

Qualitative Filter Paper

  • Qualitative grades of filter paper are, by definition, recommended for use in analytical methods, which determine or identify particulate constituents of a mixture irrespective of the amount present. Qualitative filter papers are often used in routine separation work that still requires high purity and consistent performance.

Quantitative Filter Paper

  • Ashless Qualitative Filter Paper is used in several test methods. Commonly used filters in many standardized test methods, like gravimetric analysis and sample preparations. where a high-purity filter is preferred. Standard ashless grades do not contain any reinforcement agents.
  • Hardened Low-Ash Filters – (Ash 0.01%) Suitable for routine gravimetric analysis and typical preparation of samples for use in analysis involving instrumental techniques. Low ash grades have intermediate ash content between qualitative grades and ashless grades.
  • Hardened Ashless Grades (Ash 0.006%) These specially treated hardened ashless grades are available for critical quantitative analytical techniques requiring increased wet-strength and handling capacity. – Tough, smooth surface of these filters is free of loose fibers to better collect wet precipitates. – Manufactured from top quality cotton linters using ultra-pure, reverse-osmosis water and further treated with dilute acid to remove organic and inorganic impurities. – High chemical resistance to strong acid and alkali solutions.

Cellulose Chromatography Paper

  • Our Great Lakes paper product line also includes chromatography, electrophoresis and blotting paper for use in gel transfer applications and chromatography techniques. These uniform, smooth, white sheets are the high purity, high quality, and high-value standard. They are used in nucleic acid research such as Southern, Northern and Western blots, electroblotting and electrophoresis. The chromatography, electrophoresis and blotting papers are made from high purity and 100% FDA compliant alpha cotton cellulose, using ultra-pure RO water and contain no additives that could cause increased backgrounds or other interference in detection systems.
    • Key Features:
      • Controlled absorption
      • Uniform absorption
      • Consistency across the sheet
      • Lot-to-lot consistency
      • High purity, no sizing or fillers
      • Excellent wet-strength and handling
      • No hard spots or density variations
      • No airborne fibers
      • Custom cut
      • Bulk packaging

Pre-Folded Qualitative Filter Paper

  • Ask about our pleated grades. They allow a faster flow rates and pleating improves the effective surface area increasing flow rate and loading capacity thus decreasing filtration time. Pleated circles are available in 125mm to 500mm diameters.

Glass Microfiber Filters

  • Glass microfiber filters are manufactured out 100% pure borosilicate glass. Glass microfiber filters have wide applications in many areas of laboratory analysis, especially when fine filtration and high loading capacity is required. Applications for glass microfiber filters include environmental analysis for water, wastewater, testing of soils, air pollution and monitoring, research and process biochemistry, and gravimetric analysis involving ignition of samples.
