Whatman® qualitative filter paper, Grade 2
circles, diam. 125 mm, pack of 100
General description
These cellulose filters are used in qualitative analytical techniques to determine and identify materials. Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters.
Grade 2: 8 μm, (medium flow filter paper)
Slightly more retentive than Grade 1 with a corresponding increase in filtration time (i.e., slightly slower filtration speed). More absorbent than Grade 1. In addition to general filtration in the 8 μm particle size range, the extra absorbency is utilized, for example, to hold soil nutrient in plant growth trials. Also used for monitoring specific contaminants in the atmosphere and in soil testing.
Other Notes
Field of Use : For internal research use only. Products are not intended for diagnostic use or resale.

SCANCIA Borate Flux and additive selection
To make sure we could cover every application, we have 2 purity grades (99.99 & 99.998%, metal basis) and an extensive range of formulations. If you can′t find yours here, just ask: we also make custom formulations.
What makes our fluxes different? Besides being the purest, they are far homogeneous than most fluxes, they have integrated non-wetting agents, flows easily, are less hygroscopic and are backed by Scancia′s dedicated scientists making only one thing: flux.
The basic compositions range from Lithium Tetraborate (LiT – Li₂B₄O₇) to Lithium Metaborate (LiM – LiBO₂)
