DURAN exsiccator DN 300 with knob lid, flat flange, without connection

DURAN® exsiccator with knob lid, DN 300 The DURAN® exsiccator is a vacuum-suitable laboratory vessel with ground-glass lid, which is used for storing moisture-sensitive substances and for drying moist products. Separated by a sieve plate (made of metal or porcelain), a drying agent is placed in the lower part of the exsiccator base; it binds the moisture of the substance to be dried, which is placed on the sieve plate. The drying process can optionally be accelerated by connecting a vacuum, since the liquid evaporates faster at a lower pressure in the exsiccator. The vacuum is applied via a stopcock connection. To make it easier to remove the lid, the flat ground joint of the exsiccator must be well greased, since after evacuation the lid is pressed onto the base. All DURAN® exsiccators are vacuum-resistant, i.e. they can be used up to the technically maximum possible vacuum. Special features and advantages: Due to the substantial wall thickness and the precise processing of the vacuum-tight ground joints on the lid and base, storage under vacuum is possible even over a longer period By connecting a vacuum to the stopcock, the drying process can be accelerated Suitable for full vacuum (0 mbar) Spare parts such as lids, bases, stopcocks and closures are compatible and can be exchanged as required (observe DN) Application: Ideal for removing moisture from solids, storing moisture-sensitive materials over long periods, for applications requiring vacuum drying, drying materials, safe working under vacuum
