These filter papers made from high quality cotton linters have the finest retention of all ashless filter paper grades. Grade 42 is designed for gravimetric analysis and sample preparation for instrumental analysis.
- Commonly used as a calcium carbonate filter
- Alpha cellulose content ≥98%
These filter papers are designed for retention of extremely small particles. Other typical precipitates for gravimetric analysis include barium sulfate and metastannic acid for use in glazes, coatings and pigments. The high purity of these filters also makes them suitable for processes that require ashing.
