A precision-ground glass joint (like a 24\/29 size) creates a much tighter seal with a matching funnel than a simple rubber stopper or \"bung\" can provide.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"dF3vjf\" data-sfc-root=\"c\" data-sfc-cb=\"\" data-hveid=\"CAEIAhAB\" data-complete=\"true\" data-sae=\"\"\u003e\u003cspan class=\"T286Pc\" data-sfc-cp=\"\" data-sfc-root=\"c\" data-sfc-cb=\"\" data-complete=\"true\"\u003e\u003cstrong class=\"Yjhzub\" data-sfc-root=\"c\" data-sfc-cb=\"\" data-complete=\"true\"\u003eRigidity and Alignment\u003c\/strong\u003e: Heavy Buchner funnels (especially ceramic ones filled with liquid) can be top-heavy.
