- Vaak gebruikt als een calciumcarbonaat filter
- Alfacellulosegehalte ≥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.
