Description:
Ahlstrom-Munksjö 9500-4000 40.00cm Qualitative Slow Speed Filter Paper, 2.0 μm Retention, Wet Strengthened. This slow flow rate grade with very good retention is used in the filtration of fine precipitates and superphosphates. Grade 950 is also recommended for boiler water analysis applications and gas filtration. 100/pack.
Qualitative wet-strengthened grades are manufactured for applications using filter paper in a system or apparatus that operates under pressure or vacuum conditions. These systems require the use of extremely strong filter paper such as those in Ahlstrom's Binder Series. These grades contain a small amount of chemically stable and insoluble binding resin that strengthens the natural fiber-to-fiber bonds under wet conditions. Grades containing wood fibers or resins containing nitrogen are not recommended for use in quantitative ashing techniques and in Kjeldahl estimations. Qualitative wet-strengthened filter papers are also used in industrial laboratories where technicians require a strong and economical filter paper with consistent quality and performance.
