Product Description
The Whatman Grade 934-AH RTU Glass Microfibre Filter | 9907-024 is a premium-quality ready-to-use (RTU) borosilicate glass microfibre filter designed for the determination of total suspended solids (TSS), dissolved solids, and volatile solids in water and wastewater analysis. The filters are pre-washed, pre-dried, cooled, desiccated, and pre-weighed, eliminating time-consuming preparation steps required by standard laboratory methods. This significantly improves laboratory efficiency while ensuring highly accurate and reproducible analytical results.
Manufactured from binder-free borosilicate glass microfibres, the Grade 934-AH RTU filter offers excellent chemical resistance, high loading capacity, and a 1.5 µm particle retention with fast filtration rates. Its fine retention characteristics make it suitable for filtering highly turbid water samples while maintaining excellent flow performance. These filters comply with US EPA Standard Method 2540 for total suspended solids analysis, making them a trusted choice for environmental laboratories and regulatory testing.
The 9907-024 variant consists of 24 mm diameter ready-to-use filter discs supplied in packs of 100. Each filter is packaged in an individual aluminum weighing pan with barcode identification, allowing laboratories to eliminate manual weighing and improve traceability. The filters are widely used in environmental monitoring, wastewater treatment plants, pharmaceutical laboratories, research institutions, industrial quality control laboratories, and academic facilities requiring reliable gravimetric analysis.
