Whatman Glass Microfiber Filter PapersWhatman glass microfiber filter paper includes grade GF/A, GF/B, GF/C, GF/D, GF/F, 934-AH, GF6, GF8, GF10, GF92 and more . Whatman offers two types of glass microfiber filters manufactured from 100 percent borosilicate glass: binder-free glass microfiber that is chemically inert and binder glass microfiber. These depth filters combine fast flow rates with high loading capacity and the retention of very fine particles, extending into the sub-micro range.
Whatman Qualitative Filter PapersWhatman qualitative filter paper includes grade 1, 2, 3, 4, 5, 6, 591, 595, 597, 596, 602 h, 113, 114, 91, 93, 113, 114, 588, 1573, 1575 and more. These cellulose filters are used in qualitative analytical techniques to determine and identify materials. Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters.
Whatman Quantitative Filter PapersWhatman qualitative filter paper includes grades 40, 41, 42, 43, 44, 589/1, 589/2, 589/3, 50, 52, 54, 540, 541, 542 and more. Whatman Quantitative FIlter papers are designed for gravimetric analysis and the preparation of samples for instrumental analysis. They are available in three formats to meet your specific needs: ashless, hardened low ash and hardened ashless.
Whatman Quartz Fiber Filter PapersWhatman quartz fiber filter paper includes grades QM-A, QM-B and QM-H. High-purity quartz (SiO2) microfiber filters are used for air sampling in acidic gases, stacks, flues, and aerosols, particularly at high temperatures up to 800°C and in PM2.5/PM10 and trace element analysis. Due to the low level of alkaline earth metals, artifact products of sulfates and nitrates (from SO2 and NO2) are virtually eliminated.
