General description: | Whatman quantitative filters are designed for gravimetric analysis and the preparation of samples for instrumental analysis. They are available in three formats designed to meet your specific needs. Ashless: 0.007% ash maximum for Grades 40 to 44 and a maximum of 0.01% for the 589 Grades-very pure filters suitable for a wide range of critical analytical filtration procedures. Hardened low ash: 0.015% ash maximum-treated with a strong acid to remove trace metals and produce high wet strength and chemical resistance. These filters are particularly suitable for Büchner filtration where the tough smooth surface of the filter makes it easy to recover precipitates. Hardened ashless: 0.006% ash maximum-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. Grade 589/3: <2 μm (slow filter paper) ‘Blue Ribbon Filter’, ashless standard filter paper for very fine precipitates (class 2d acc. to DIN 53 135). Slow filter paper with highest efficiency for collecting very small particles. Also used for many analytical routine methods in different industries, e.g., determination of the amount of insoluble contaminants in animal and vegetable fats and oils. |
