Cytiva
Filter Circles, Qualitative, Grade 50
Retention of very fine crystalline precipitates. The thinnest of all Whatman filter papers. Slow flow rate. Hardened and highly glazed surface. This finish also keeps the paper free from loose surface fibres. Highly suitable for qualitative or quantitative filtrations requiring vacuum assistance on Büchner or 3-piece filter funnels.
Will withstand wet handling and precipitate removal by scraping. In the electronics industry, the virtual absence of fiber shedding is utilised in carriers for integrated circuits.
- Very strong when wet.
- Hardened low ash grades.
