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.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"DSCBalances","offers":[{"title":"10311887","offer_id":36822125772950,"sku":"10311887","price":2272.27,"currency_code":"USD","in_stock":true},{"title":"10311897","offer_id":36822127116438,"sku":"10311897","price":392.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0489\/6990\/8374\/files\/digi-28804-original-png.jpg?v=1792610692","url":"https:\/\/www.dscbalances.com\/products\/whatman-grade-588-qualitative-filter-papers","provider":"DSCBalances","version":"1.0","type":"link"}
