These cellulose filters are used in qualitative analytical techniques to determine and identify materials.
| Code | Whatmans Grade 3 |
- Pre-pleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters.
Grade 3 (6 µm):
- Double the thickness of Grade 1 with still finer particle retention and excellent loading capacity; more precipitate can be held without clogging.
- The extra thickness gives increased wet strength and makes this grade highly suitable for use in Büchner funnels.
- The high absorbency is particularly valuable when the paper is used as a sample carrier.
- This filter is also available in the Filter Cup.
- This is a convenient, disposable 70 mm filter funnel with a 250 ml capacity moulded from polypropylene with an integral, heat bonded filter.
