General description

A general qualitative filter for less critical routine analysis. Widely used in industrial laboratories and students laboratories for routine filtration. Reeve Angel products are designed for routine, repetitive applications for which an inexpensive product is acceptable, such as qualitative analysis. Reeve Angel products deliver as promised, every time. The filter is wet-strengthened with a small amount of chemically stable resin to extend the life of the filter and improve handling. Normal qualitative applications will not introduce any significant impurities into the filtrate. However it is not recommended for Kjeldahl nitrogen analysis.

Features and Benefits

  • Retains medium-fine precipitates
  • Relatively slow filtration speed
  • Smooth surface and close texture
  • For general-purpose qualitative analysis
