GR 541 40CM 100/PK
These are the supreme quantitative filter papers featuring high wet strength and chemical resistance. These papers are acid-hardened, which reduces ash to an extremely low level. The tough surfaces pf these fillters make them suitable for a wide range of critical alytical filtration operations. Each grade offers a convenient combition of filtration speed and particle retention.Fast filtration of coarse particles and gelatinous precipitates in acid/alkali solutions during gravimetric alysis. Typical applications include determining fiber in animal foodstuffs, gelatin in milk and cream, chloride in cement, and chloride and phosphorous in coal and coke.Hardened ashless: .6% ash maximum. These filters are acid-hardened to give high wet strength and chemical resistance with extremely low ash content. The tough surface makes these filters suitable for a wide range of critical filtration procedures.
