Cytiva Qualitative Filter Papers, Circles, Grade 2, 8 um, 38.5 cm

This certified Grade 2 filter paper is tested according to the procedure detailed in ASTM E 2187-09, Sections 9.3.1 and 9.3.2. The paper meets both the conditioned (26.1 +/- 0.5 g, SD < 0.3 g) and dried (24.7 +/- 0.5 g, SD < 0.3 g) weight requirements. These cellulose filters are used in qualitative analytical techniques to determine and identify materials.

• Each lot is guaranteed to meet the ASTM E 2187-09 specifications
• Simplifies testing process by removing lot suitability testing
• Just condition and use
