Whatman 1827-110 Filter Circles, 110mm Dia, Binder Free Grade 934-AH, 100/pk (PN:1827-110)

These glass microfiber filter circles are designed for filtration of liquids containing suspended solids. They are widely used in environmental, water, and laboratory testing to remove turbidity and capture fine particulates from large sample volumes.

The Grade 934-AH filters have a nominal particle retention of 1.5 µm, meaning they effectively retain particles and solids that are larger than this size. This makes them suitable for total suspended solids (TSS) analysis and clarification applications.

These filters are made from binder-free borosilicate glass microfiber, which provides a smooth surface, high loading capacity, and resistance to high temperatures (up to ~500 °C), making them durable for laboratory filtration tasks.

This pack contains 100 individual filter circles, each with a 110 mm diameter — ideal for use with standard laboratory funnels and vacuum filtration setups that accept larger filter media.

Yes — the binder-free glass microfiber circles are provided ready to use, but because they are non-sterile, you should follow appropriate lab procedures if sterility is required for specific applications.
