Ahlstrom 616513 Glass Quantitative Filter Papers, Grade 615, 12.5cm Diameter (Pack of 5000)

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, 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, or in Kjeldahl estimations
