Filtry jakościowe Grade 114

Filtry o połowę cieńsze niż Grade 113, odpowiednie do wytrącania gruboziarnistych lub żelatynowych osadów. Gładka powierzchnia umożliwia łatwe odzyskanie osadu.
Only half the thickness of Grade 113 and suitable for coarse or gelatinous precipitates. Smooth surface for easy recovery of precipitates.

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.

Also available prepleated as Grade 114V.
