Qualitative Filter Paper Grade 237 (=3)

Standard Grade (Non Wet-Strengthened)

Standard qualitative filter paper is suitable for quadrant folded or gravity flow applications. This grade contains a high level of alpha-cellulose that provides high purity but will weaken when wet. The inherent strength of standard (untreated) grade does not pose a problem when they are used in routine quadrant folded applications. We do not recommend this grade for use in vacuum work or when wet handling is required.
