DESICCATORS
DURAN® desiccators are used for drying moist substances or as storage vessels for moisture-sensitive products. To accelerate the drying process, the desiccators can be used under vacuum. 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.
All individual parts and a wide range of accessories such as lids, stopcocks, bases, etc. are compatible and can be interchanged as required. Always ensure the individual parts have the same DN (nominal diameter).
For desiccators, the DN is based on the diameter of the sieve plate; this can be measured directly. For lids, measure the outside diameter of the flange and crossreference with the tables on the product pages.
Usage tips:
- Designed for use under absolute vacuum.
- 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 a naked flame.
- Before evacuation, it is recommended that the glass surfaces of the desiccator be checked for damage such as scratches, cracks or nicks. Damaged desiccators must not be used for safety reasons.
- Never expose desiccators to abrupt pressure changes (do not suddenly ventilate evacuated vessels).
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.
