Supreme quantitative filter papers offering medium retention and flow rate.
- Hardened ashless: 0.006% 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.
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 analytical filtration operations. Each grade offers a convenient combination of filtration speed and particle retention.
Grade 540: 8 µm
The general purpose hardened ashless filter paper with medium retention and flow rate. Extremely pure and strong with a hard surface. High chemical resistance to strong acid and alkali. Frequently used in the gravimetric analysis of metals in acid/alkali solutions and in collecting hydroxides after precipitation by strong alkalis.
