General description

Cytiva′s Whatman Grade 113V creped filter paper, for use with a conical filter funnel, offers fast filtration and high loading capacity for analysis involving coarse particles or gelatinous precipitates.

Note: Grade 113V is strengthened with chemically stable resin. However, these paper filters do contain nitrogen and should therefore not be used in Kjeldahl estimations or other nitrogen-sensitive procedures.

Wet-strengthened creped filter paper

Creped filter paper, which has a rough surface, is designed to increase loading capacity. Fluted (pre-pleated) paper filters eliminate the need to quadrant-fold circles in repetitive or multiple analyses.

Whatman Grade 113V paper filters from Cytiva′s business are further strengthened with chemically stable resin that increases wet-strength without introducing significant impurities to the filtrate. Strengthening the paper expands the range of sample types that can be separated in a conical filter funnel.

Features and Benefits

  • Extremely Fast filtration (Herzberg 28s)
  • Wet-strengthened with chemically stable resin
  • Retention of coarse particles: nominal particle retention rating of 30 µm
  • Creped filter paper supports high loading capacity
  • Fluted (pre-pleated) for easy use in applications involving a conical filter funnel
