GF／A-高效常規(guī)過濾紙。適合于收集各種水中的懸浮物，過濾水中的顆粒、藻類和細(xì)菌培養(yǎng)液等。并且廣泛地應(yīng)用于空氣污染監(jiān)測(cè)。
GF／B-比GF／A厚，濕強(qiáng)度更高，負(fù)載力亦更強(qiáng)。推薦用于濃縮細(xì)小顆粒狀的懸浮物和每平方厘米含水量高達(dá)68．5毫克的特別技術(shù)需求。適合于工業(yè)污水中大量懸浮物的收集。
GF／C-是常規(guī)水中懸浮物測(cè)定標(biāo)準(zhǔn)方法中用濾紙，也用于溶劑的澄清和細(xì)菌培養(yǎng)液過濾。在生化方面廣泛用于細(xì)胞收集、液閃計(jì)數(shù)和結(jié)合分析測(cè)驗(yàn)。
GF／D- —般用于預(yù)濾，負(fù)載力強(qiáng)。
GF／F-細(xì)微顆粒的過濾保留率*。適用于要求較嚴(yán)格的應(yīng)用如沙門菌和綠膿桿菌、蛋白溶液的過濾、HPLC分析前的樣品和溶劑過濾。
