They are manufactured from 100% cotton linters with an alpha-cellulose content of greater than 98% and are acid-washed to achieve ash-free status and high purity. Available in packs of 100 pieces, these Grade 391 papers from manufacturer Sartorius are produced from pure cotton-linter feedstock for laboratory filtration. Acid washing delivers the ash-free character and high purity linked to an alpha-cellulose content above 98%. The papers are intended for quantitative work, gravimetric determinations, and filtration performed under pressure or vacuum. With a net weight of 102,000 kg, the pack supplies ash-free cellulose sheets for analytical filtration tasks. Grade 391 quantitative filter papers therefore combine 100% cotton-linter material, acid-washed processing, and a 100-piece pack format for laboratories requiring high-purity filter media.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/filter-paper\"\u003eFilter paper\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/filtration\"\u003eFiltration\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 100 pc(s)\u003c\/li\u003e\n\u003cli\u003eStorage temperature: Room temperature\u003c\/li\u003e\n\u003cli\u003eGrade: 391\u003c\/li\u003e\n\u003cli\u003eMaterial: 100% cotton linters\u003c\/li\u003e\n\u003cli\u003eAlpha-cellulose content: \u0026gt; 98%\u003c\/li\u003e\n\u003cli\u003eProcessing: Acid-washed\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sartorius","offers":[{"title":"Default Title","offer_id":57997918699852,"sku":"FT4104110","price":75.7,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/idl-FT4104110.png?v=1783731592","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/quantitative-papers-grade-391-110-mm-blue-dot-quantitative-folded-filter-paper","provider":"Luminix Health","version":"1.0","type":"link"}
