DURAN® Vacuum Desiccator

with NOVUS standard ground joint (NS 24/29) junction tube in the lid, stopcock and flat flange

Vacuum-tight, made from DURAN® borosilicate glass 3.3. To accelerate drying, a vacuum can be applied via the stopcock. Spare parts such as lids, bases, stopcocks and caps can be interchanged (observe DN). 

Typical applications: 
Drying of moist samples and storage of moisture-sensitive substances.

Attention: The safety instructions are only valid for original DURAN® products. Therefore, please pay attention to the SCHOTT DURAN® trademark which guarantees proven DURAN® quality and highest safety during application. Working under vacuum • Vacuum-tight due to their special geometry and high wall thickness,

i.e. they can be used up to the technically maximum possible vacuum. • Optimum safety for user. • DURAN® desiccators conform with DIN 12491. • Due to the high wall thickness and the reduced thermal shock resistance under pressure loading, the desiccators must not be heated on one side only or heated using an open flame (see also chapter 5.1.6 „Richtlinie für Laboratorien“ BGR/ GUV-R 120). • Before evacuation, the glass surfaces of the DURAN® desiccators have to be checked for damages such as scratches, cracks or nicks. Damaged products must not be used for safety reasons (see also chapter 5.1.6 „Richtlinie für Laboratorien“ BGR/ GUV-R 120). • Never expose desiccators to abrupt pressure changes (do not suddenly ventilate evacuated vessels). 2 • When used under positive or negative pressure, and especially when also working with differential temperatures, additional care measures must be taken. • Glass apparatus that is under pressure or vacuum should only be subject to further strain (e.g. significant temperature change) with extreme caution, as the individual resulting stresses are additive and could readily result in failure. • Due to the high wall-thickness of the vessels and the exact machining of the vacuum-tight ground joints on the lid and base, storage under vacuum is possible - even over extremely long periods. • Before using, the ground joints must be well greased with appropriate joint grease.
