DURAN® Flat Flange Lid, 4 standard ground necks (3 angled side and 1 center)

DURAN® Flat Flange Lid, with side necks: 2 x NS 19/26 angled and 1 x NS 14/23 angled, DN 60Flat flange vessels are large volume reaction vessels which are regarded as an alternative to the round flasks and consist of a bottom part and a lid. These two parts are held together by means of a clamping ring. A seal or grinding grease prevent the grinding surfaces from tilting. The flat flange vessel can be combined with other components (e.g. dropping funnels, stirring shafts, ...) by means of various standard ground joints in the lid. Flat flange vessels are well suited for preparative work such as general reactions, distillations, evaporation and drying of solid and viscous substances. Due to their walls, flat flange vessels are suitable for safe working under pressure and vacuum.Features and Benefits:With one middle neck: 29/32 and three side necks (standard ground): 2 x 19/26 angled; 1 x 14/23 angledPressure and vacuum resistant due to the wall thickness and geometryTight closure due to standard ground jointApplication: Chemically and thermally demanding processes, Safe working under pressure or vacuum, At the maximum usage temperature of 250 °C and the maximum operating pressure, the temperature difference in the glass wall of the flat flange reaction vessels must not exceed 30 °C. more
