Efficient Filtration, Durable Material

Based on our own experience this lab filter provides excellent filtration with a durable material that can withstand tough lab conditions. Its quantitative filter properties provide accurate and reliable measurements. The only downside is its slightly higher price point compared to other lab filters .Overall, an exceptional product worth investing in for reliable and efficient filtration..

Pros
  • Provides accurate and precise quantitative analysis results
Cons
  • Has a small diameter which may limit the amount of sample that can be filtered at once

Quality papers on the Whatman website. Works very well

This is not a quantitative filter paper. According to the GE Lifesciences website (maker of Whatman filter paper), grade 598 filter paper is a quality filter paper. I have used them to filter functionalized silica with particle sizes from 60 to 250 µm and they have worked great. A pore size of 8-10 µm was excellent for our use. Lost a star due to false claim about quantitatively sorted filter paper.

Pros
  • Diameter: 90mm
Cons
  • Some bugs
