The Buchner listings describe vacuum-filtration use. Look for the cylindrical cup and perforated plate, then check the exact item dimensions. The side-arm flask, adapter, vacuum apparatus and filter paper shown in a use scene are not part of the funnel purchase.

The Eisco Labs 13cm I.D. Buchner funnel and its 6-pack explicitly state this filter-paper range. It is not a fit specification for the 7.5cm or 9cm hBARSCI options.

The four-piece transfer set contains four different sizes: 2.25, 2.75, 3.25 and 3.9in. The 10-pack filter funnels contain ten funnels in the one selected diameter. Buchner case listings are identified separately.

The selected funnel, set or pack stated in its listing. Surrounding labware in a scene, such as a flask, beaker, hose, pump, rack or filter paper, is not included unless the item listing expressly says so.
