FLAT FLANGE RANGE
The DURAN® flat flange reaction vessels are valued for their universal suitability for use in the laboratories of a wide range of specialisations. Whether for reaction, distillation, evaporation or desiccation, DWK Life Sciences offers a wide range of unfinished and finished parts which always provide the optimum solution for the particular application. Due to the pure glass-glass connections, reactions with highly corrosive or highly chemically reactive substances can be carried out without problem. The vessels are notable due to a robust glass flange design with an optimum flange angle of 45°. The proven flange design (flat ground) is available with groove, consequently O-rings can be used. The corresponding stainless-steel quick release clamps with three flexible retaining clips ensure easy and safe handling. All individual parts and a wide range of accessories such as lids, O-rings and quick- release clamps etc. are compatible and can be interchanged as required. In so doing however, you must always ensure the same DN (nominal diameter) of the individual parts applies. Recommendations • All components are suitable for use under an absolute vacuum (- 1 bar). Many are rated for positive pressure operation (see product descriptions for details) • Before use, it is recommended that the glass surfaces be checked for damage such as scratches, cracks or nicks. • Damaged glassware should not be used for safety reasons. • Due to the high wall thickness and reduced thermal shock resistance under pressure loading, the flat flange vessels should be heated uniformly and gradually.
