About this item
Cytiva's Whatman Grade 42 quantitative papers have the finest retention of all Whatman ashless filter paper grades. Grade 42 is designed for gravimetric analysis and sample preparation for instrumental analysis.
- Fine (2.5 µm) nominal particle retention rating, eliminates large particles that might otherwise interfere with sensitive instrumentation
- Commonly used as a calcium carbonate filter
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.
