Ashless grades are very pure filters suitable for a wide range of critical analytical filtration procedures. Whatman quantitative filter papers are designed for gravimetric analysis and the preparation of samples for instrumental analysis.
Ashless: 0.007% ash maximum
Fine (2.5 µm) nominal particle retention rating, eliminates large particles that might otherwise interfere with sensitive instrumentation
Herzberg filtration speed of 1870 s
Commonly used as a calcium carbonate filter
High-quality Cotton Linters
Highly retentive, for very fine precipitates. Normal loading; limited wet strength. Laboratory standard for critical gravimetric analysis
