Filtry jakościowe Grade 1575

Wolny papier filtracyjny o wysokiej wytrzymałości w stanie mokrym. Papier ten ma takie same właściwości w zakresie odporności chemicznej jak papier klasy 1573.
Slow filter paper with high wet strength. This paper has the same chemical resistance characteristics as Grade 1573.

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.
