Whatman 1541-400, 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 Filters make them suitable for a wide range of critical analytical filtration operations. Each grade offers a convenient combination of filtration speed and particle retention.

Fast filtration of coarse particles and gelatinous precipitates in acid/alkali solutions during gravimetric analysis. Typical applications include determining fiber in animal foodstuffs, gelatin in milk and cream, chloride in cement, and chloride and phosphorous in coal and coke.

Features:

• 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.
