说明

一般說明

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. The resins do, however, contain nitrogen so these grades should not be used in Kjeldahl estimations, etc. Some wet strengthened grades are available in folded (prepleated) forms.

Grade 114: 25 μm (fast, smooth filter paper)
Only half the thickness of Grade 113 and suitable for coarse and gelatinous precipitates. Smooth surface for easy removal of precipitates.
