Micro-quartz filters are useful for testing hot "stack" gases as the quartz fibers can withstand temperatures up to 900 °C. In addition, micro-quartz is used when the highest purity media is required. With excellent filtration properties and minimal traces of metals and minerals, quartz fibers are dimensionally stable and can be used in the analysis of acidic gases with the exception of hydrofluoric acid.

These syringe filters are suitable for convenient sample preparation and fluid sterilization. The syringe filters for highly loaded aqueous solutions including a glass fiber prefilter and a cellulose acetate membrane are also available with MBS housing and male Luer lock outlet.

Ahlstrom-Munksjö’s qualitative grades of filter paper are 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. These filter papers covers a wide range of laboratory applications, as liquids clarification, qualitative analytical separations for precipitates and buffers filtration, and are also used for soil analysis and in food and beverage testing. Wet-strengthened grades contain a reinforcement agent that increases their resistance to rupture when wet, such as in vacuum filtration, and their resistance when filtering acidic solutions. High Purity hardened filter papers grades 1288 to 1291 are also produced from cellulose with an alpha content of nearly 100% resulting in an ash content of <0,1%.

Ahlstrom-Munksjö manufactures a series of extremely high purity, acid washed filter papers designed for use in analytical and gravimetric analysis. The quantitative grades are manufactured from top quality cotton linters using ultra-pure, deionised water and are further treated with dilute acid to remove any remaining organic and inorganic impurities. All quantitative grades are manufactured in a strictly controlled environment that ensures high uniformity and high purity from filter to filter.
