![]() | WhatmanGrade1定性濾紙1001-090 GR 1 9.0CM 100/PKWhatman定性濾紙用于定性分析技術中鑒定物質的性質。折疊好的定性濾紙與相同型號平整的濾紙相比,加快了流速和增加了負載力 |

![]() | WhatmanGrade2定性濾紙1002-055 GR 2 5.5CM 100/PK比Grade 1保留力略強,但過濾時間卻相對長些(也就是過濾速度相對慢些),比Grade1吸附性更強。除了8 μm大小顆粒的普通過濾之外,它額外的吸附性能也派上了用場,例如在植物生長實驗中截留土壤營養物質,監測空氣和土壤中的特殊污染物等,還是肉類、明膠、飼料、藥品、維生素、西紅柿、嬰幼兒奶粉等測定用標準分析濾紙。已折疊好的為Grade 2V。 |

![]() | Whatman Grade3定性濾紙1003-323 GR3 2.3CM 100/PK厚度是Grade 1的兩倍。負載力好,顆粒保留較小,無堵塞便可得到更多沉淀物。由于其濕強度好,適合放在布氏漏斗中使用。其高吸附性能可用作樣品的載體是飼料中哌嗪、乳制品中山梨酸測定的標準濾紙。 |
