Product Overview

The DURAN® desiccator is a vacuum-suitable laboratory vessel with a ground 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 introduced into the lower part of the desiccator base, which binds the moisture of the substance to be dried, placed on the sieve plate. To accelerate the drying process, a vacuum can be connected if necessary, as the liquid evaporates faster due to a lower pressure in the desiccator. The vacuum is applied via a shut-off valve connection. To facilitate loosening of the lid, the surface grinding of the desiccator must be well greased, since after evacuation the lid is pressed onto the lower part. All DURAN® desiccators are vacuum-resistant, i.e. they can be used up to the technically maximum possible vacuum.

Boro 3.3 = Borosilicate glass 3.3 has a very good chemical resistance, virtual inert behavior, a high maximum usage temperature, high light transparency and minimal thermal expansion. Borosilicate glass 3.3 has a linear coefficient of expansion of 3.3 × 10−6 K−1 at 20 °C. It also conforms to the requirements of a USP/EP/JP Type 1 neutral glass suitable for use by the pharmaceutical industry. The properties of DURAN® are specified to ISO 3585 and ASTM-E438 Type 1 Class A.
