Whatman 2827-047 Grade 934-AH RTU Glass Microfiber Filter, 4.7cm, 100/PK

RTU means the filters are pre-washed, pre-weighed, and ready for immediate use, eliminating the need for preparation before testing. This saves time and ensures consistent, reproducible results, especially in regulated methods like total suspended solids (TSS) analysis.

These filters are widely used for total suspended solids (TSS), total dissolved solids (TDS), and volatile solids analysis in water testing. They are also suitable for environmental monitoring, wastewater analysis, and air pollution studies.

The 934-AH RTU filter provides approximately 1.5 µm particle retention with high flow rates, allowing efficient filtration of fine particles even in turbid or high-load samples.

These filters are made from high-purity borosilicate glass microfiber, offering low extractables, minimal fiber shedding, and high temperature resistance (up to ~550°C). This makes them ideal for gravimetric and high-temperature analytical methods.

These filters meet Standard Methods (e.g., 2540D) for water testing, ensuring compliance with widely accepted analytical procedures. Their consistent weight, high loading capacity, and reliable retention make them a trusted choice for accurate environmental and laboratory measurements.
