Filter Papers – Professional Grade 1, Box of 100 (18.5cm Diameter)

These Professional Grade 1 Filter Papers (18.5cm diameter) are high quality laboratory consumables designed for accurate, consistent filtration in educational and professional science environments. Ideal for larger scale practical work, they provide reliable performance where precision and repeatability are required.

Designed for quantitative analysis, these filter papers are a Whatman No. 1 equivalent, offering a balanced combination of a medium particle retention rate and a medium to fast flow rate. This makes them well suited to general purpose laboratory filtration, allowing efficient separation without sacrificing clarity or accuracy. Supplied as a box of 100 circular filter papers, each with a generous 18.5cm diameter, they are ideal for use with large Büchner funnels and high volume filtration setups.

Consistent, durable, and dependable, these professional grade filter papers are an excellent choice for busy science departments and advanced practical investigations.
