This funnel has a 3-liter capacity, making it suitable for filtering substantial volumes of mixtures. A key feature is the frit, a porous glass disc integrated into the funnel that supports the filter paper and effectively retains solid precipitates while allowing the liquid to pass through under vacuum.\u003c\/p\u003e\n\u003cp\u003eThe lower vacuum assembly indicates that the funnel is specifically designed to be the lower part of a vacuum filtration assembly, connecting to a vacuum flask via a ground glass joint. Buchner funnels are commonly used in chemistry and other laboratories for tasks such as collecting synthesized solid products, purifying substances by removing particulate matter, and preparing samples for further analysis.\u003c\/p\u003e\n\u003cp\u003eConstructed from scientific-grade borosilicate glass, the Whelan Scientific Glass 3L Buchner Filter Funnel with its Coarse frit and lower vacuum design provides a reliable and effective method for laboratory-scale filtration of larger volumes, especially when dealing with fine solids.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUsed; excellent condition.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Whelan Glass","offers":[{"title":"Default Title","offer_id":47184828170492,"sku":"9245","price":323.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/8463\/5132\/files\/whelan-scientific-glass-3l-buchner-filter-funnel-lower-vacuum-fine-frit-glassware-whelan-glass-948075.jpg?v=1747576836","url":"https:\/\/lifesciencestrading.com\/zh\/products\/whelan-scientific-glass-3l-buchner-filter-funnel-lower-vacuum-coarse-frit","provider":"Life Sciences Trading","version":"1.0","type":"link"}
