125mm Medium Flow Quantitative Filter Paper (Box of 100)
The 125mm Medium Flow Quantitative Filter Paper from Eisco is a medium speed filter paper for routine analytical and teaching applications using standard funnels. This 125mm filter paper helps you achieve reliable separation of fine particles at a 10 ยตm nominal pore size.
Its 85 gsm construction offers good strength when wet and a moderate filtration rate, making it suitable for clarifying a wide range of aqueous samples, from reaction mixtures to environmental water tests. The 125mm diameter suits common conical and Bรผchner funnels used with mid-scale sample volumes, giving you enough surface area to avoid frequent clogging. Each box contains 100 discs, ideal for multi-user labs and student courses.
Practical Applications
– General purpose qualitative filtration in analytical chemistry workflows
– Clarifying reaction mixtures prior to further processing or analysis
– Filtration in teaching labs for titrations, precipitation reactions and separations
– Sample preparation for colourimetric or spectrophotometric measurements
– Use with medium sized Bรผchner funnels for vacuum filtration
