DURAN® flat flange cover, DN 60, vacuum-tight, 4 necks, MH NS 29/32, SH 2xNS 19/26 u. 1x NS 14/23 slanted

DURAN® flat flanged lids, with side necks: 2 x NS 19/26 oblique and 1 x NS 14/23 oblique, DN 60 Flat flange vessels are large-volume reaction vessels which are regarded as an alternative to round-bottom flasks and consist of a base and a lid. These two parts are held together by means of a clamping ring. A seal or ground-glass grease prevents the ground-glass surfaces from jamming. Various standard ground joints in the lid allow the flat flange vessel to be combined with other components (e.g. dropping funnels, stirrer shafts, etc.). Plan flange vessels are well suited for preprative work such as general reactions, distillations, evaporations and dryings involving solid and viscous substances. Because of their walls, flat flange vessels are suitable for safe work under pressure and vacuum. Special features and advantages: With one middle neck (NS): 29/32 and three side necks (NS): 2 x 19/26 oblique; 1 x 14/23 oblique Pressure and vacuum resistant due to geometry and solid wall thickness Tight closure due to standard ground joint Application: Chemically and thermally demanding processes, Safe working under pressure or vacuum, At maximum application temperature of 250 °C at permissible operating overpressure, the temperature difference in the glass wall of plan flange reaction vessels must not exceed 30 °C.
