Filtry jakościowe Grade 113

Bardzo duży ładunek połączony z odpowiednią retencją cząstek sprawia, iż są one idealne do stosowania z gruboziarnistymi lub galaretowatymi osadami. Najszybszy przepływ spośród wszystkich filtrów jakościowych. Powierzchnia fałdowana. Najgrubszy papier spośród wszystkich filtrów jakościowych.
Ultra high loading capacity with a particle retention well suited for use with coarse or gelatinous precipitates. Fastest flow rate of the qualitative grades. Creped surface. Thickest filter paper in the qualitative range.

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.

This filter is also available in the FilterCup, a convenient, disposable 70 mm filter funnel with a 250 ml capacity, molded from polypropylene with an integral, heat bonded filter. Also available as Grade 113V.
