Whatman 1002-042 Filter Circles, 42.5mm Dia, Grade 2, 100/pk (PN:1002-042)

Whatman Grade 2 filter papers are commonly used for routine laboratory filtration, environmental testing, soil analysis, and general sample preparation. They are ideal when you need moderate particle retention with reliable flow rates for everyday analytical work.

Grade 2 filter paper offers a particle retention of approximately 8 µm and a medium filtration speed. It is slightly more retentive than Grade 1, which means better particle capture but a slightly slower filtration time.

These filters are made from high-quality cellulose fibers, ensuring consistent porosity, good absorbency, and reliable performance. This material is widely trusted for producing reproducible results in qualitative analysis.

You should choose Grade 2 when you need better particle retention than Grade 1 without significantly sacrificing filtration speed. It is a great middle-ground option for applications that require both efficiency and improved clarity.

The 42.5 mm diameter is compatible with many standard small filtration funnels and holders, making it ideal for low-volume sample filtration and routine lab testing without requiring large filter setups.
