Whatman 1827-024 Filter Circles, 24mm Dia, Binder Free Grade 934-AH, 100/pk (PN:1827-024)

Whatman Grade 934-AH glass microfiber filters are widely used for total suspended solids (TSS) analysis, water quality testing, and environmental monitoring. They are also suitable for applications such as cell harvesting, liquid scintillation counting, and air pollution sampling in laboratory environments.

This filter has a nominal particle retention of approximately 1.5 µm, allowing it to efficiently capture fine suspended particles while maintaining a fast filtration rate for large sample volumes.

Binder-free filters like the Whatman 934-AH are made from high-purity borosilicate glass microfibers, which reduces contamination risk and improves chemical compatibility. The binder-free construction also helps maintain high filtration efficiency and minimal fiber shedding during testing.

Yes. These filters are designed to tolerate high temperatures up to about 500–550 °C, making them suitable for gravimetric analysis and laboratory procedures that require heating or ashing steps.

Grade 934-AH filters offer high loading capacity and fast flow rates, allowing them to process large volumes of liquid or heavily contaminated samples without clogging quickly. This makes them particularly effective for environmental water testing and suspended solids measurements.
