In laboratories across the globe, the Whatman name is synonymous with quality, reliability and ease of use. Now manufactured by Cytiva, Whatman products are specified for the most exacting applications because they work right the first time, every time.
Pronitron supplies Whatman filter paper (a Cytiva brand) to laboratories in Turkey and helps you choose the right grade. The range covers qualitative Grades 1-6, ashless quantitative Grades 40-44, hardened Grades 50, 52, 54, 540, 541 and 542, glass microfiber filters (GF/A, GF/B, GF/C, GF/D, GF/F, 934-AH, EPM 2000) and quartz filters (QM-A, QM-B, QM-C, QM-H), in circles, sheets, rolls, fluted and cone formats. Cellulose grades are made from cotton linters with at least 98% alpha cellulose; binder-free glass microfiber filters are 100% borosilicate glass, usable up to 550 °C, and GF/F retains particles down to 0.7 µm.
- Qualitative filter papers: Grades 1, 2, 3, 4, 5, 6 – routine clarification and qualitative analytical separations. Grade 1 is the most widely used filter paper.
- Quantitative ashless filter papers: Grades 40, 41, 42, 43, 44 – gravimetric analysis and sample preparation for instrumental analysis (0.007% nominal ash).
- Hardened low-ash / ashless papers: Grades 50, 52, 54, 540, 541, 542 – high wet strength and chemical resistance for Büchner filtration.
- Wet-strengthened and general-purpose papers: Grades 91, 113, 114, 1573 and the 500 series – industrial and routine applications.
- Folded and fluted filters: Ready-to-use fluted, pyramid and quadrant-folded formats for faster flow and higher loading capacity.
- Glass microfiber filters: GF/A, GF/B, GF/C, GF/D, GF/F, 934-AH, EPM 2000, TCLP and Multigrade GMF 150.
- Quartz microfiber filters: QM-A, QM-B, QM-C, QM-H – high-temperature air sampling.
- Ready-to-use (RTU) glass fiber filters: pre-washed, dried and weighed for TSS / TDS determination.
