定量濾紙（Quantitative filter paper）是專門用於重量分析與精密定量分析的濾材。定量濾紙以低棉絮、經酸洗硬化處理的高純度α-纖維素纖維製成，並以去離子水沖洗以提升純度，紙面孔隙細密且分布均勻，過濾時能截留極小顆粒，同時使液體快速通過並維持低灰分含量。定量濾紙常見於沉澱物收集、重量分析、大氣污染監測與廢水及土壤成分分析等用途。
依處理等級可分為無灰級、低灰硬化級與硬化無灰級三種形式，低灰硬化級具備較高的濕強度與化學耐受性，適合搭配布氏漏斗使用。
定量濾紙比較看孔徑（1～8 µm）：數字愈小，截留的沉澱物愈細但流速愈慢；數字愈大則流速愈快、截留顆粒愈粗。
以上為此型式規格範圍，實際規格依帶頭/貨號資料為準。
