Cytiva Whatman™ Qualitative Filter Paper: Grade 113V Circles

Description

Saves time required to quadrant-fold circles to fit conical filter funnels in repetitive or multiple analyses. Whatman™ Qualitative Filter Paper: Grade 113V Circles boast the fastest flow rate of the qualitative grades. Crepe surface promotes ultra high loading capacity.

These extremely strong filter papers have a high wet strength due to the addition of a small quantity of chemically stable resin. Normal qualitative applications will not introduce any significant impurities into the filtrate.

• Ultra high loading capacity with a particle retention well suited for use with coarse or gelatinous 
• Fastest flow rate of the qualitative grades
• Crepe surface
• Thickest filter paper in the qualitative range
• Retention of coarse particles: nominal particle retention rating of 30 μm
• Pleated for easy use in applications involving a conical filter funnel

Note: Resins contain nitrogen so these grades should not be used in Kjeldahl estimations or similar operations.
