General description
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
