Ahlstrom-Munksjo Filtration LLC
Mfg Item # : 5050-1850
Ahlstrom manufactures high quality analytical filter papers for use in specialty end use applications. These custom designed qualitative grades are manufactured from top quality cotton linters using ultra-pure, reverse-osmosis water. Ahlstrom specialty analytical filter papers include pleated and non-pleated grades and are found in applications such as seed, asphalt and beer testing. All grades are manufactured in a strictly controlled environment that ensures high uniformity and high purity from filter to filter. Key features Qualitative analysis Low ash content 0.06% Untreated Consistent performance Wet-strengthened  grades available Custom designed for  end-use application Custom cut Bulk packaging Ahlstrom offers a full range of standard pleated grades that meet your needs from grades with rapid flow rates for filtration of viscous materials to grades with tight matrices for removal of fine precipitates. Ahlstrom’s pre-pleated grades can save valuable time and maximize the efficiency of the laboratory filter system. Pleating improves the effective surface area increasing flow rate and loading capacity thus decreasing filtration time. Pleated circles are available in 12.5cm to 50cm diameters.

Ahlstrom’s 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. Ahlstrom offers a complete range of low ash filter papers for general laboratory work that provides you with the correct combination of particle retention, filtration speed, loading capacity and wet-strength. All our qualitative grades consist of > 95% super refined a-cellulose and linter fibers. Qualitative analysis Low ash content 0.06%/li> Untreated/li> Consistent performance/li> Wet-strengthened grades available/li> Custom cut/li> Bulk packaging/li> Standard Grades (Non Wet-Strengthened) Standard qualitative filter papers are suitable for quadrant folded or gravity flow applications. These grades contain a high level of alpha-cellulose that provides high purity but will weaken when wet. The inherent strength of standard (untreated) grades does not pose a problem when they are used in routine quadrant folded applications. We do not recommend these grades for use in vacuum work or when wet handling is required. Ahlstrom 609: 4Ým – Medium Speed This grade is an evolution of Ahlstrom 613 for use in the beer industry. This is a filter paper with an extremely low iron and nitrogen content for the analysis of protein in beer.
