Proper alignment of doors will prevent excessive gas escape and ensure door sensor alignment. Some leakage, however, is normal. Because cabinets operate under varying degrees of positive pressure, Terra door gaskets are designed to allow controlled gas escape.
All cabinets are checked prior to packaging to ensure proper door alignment. However, they can come out of alignment during shipping due to the inherent flexibility of plastic.
Doors feature sensor magnets that must be aligned with the associated sensor on the desiccator door. If these magnets are misaligned, the Dual Purge™ system may not function properly, and door seals may not seat properly, allowing nitrogen leakage.

Standard wall-mount pass-throughs such as CleanSeam™, BioSafe® and Terra’s plastic and intermittent-seam welded steel chambers can be installed and ready for operation in a few minutes once the wall cut-out is prepared. Refer to the Operating Manual for full installation details.
The process is straightforward, requiring the parts you receive from Terra, t
Static electricity is an excess or deficiency of electrons on a surface. The total number of deficient or excess electrons determines the charge on that surface. A surface exhibiting an excess of electrons is charged negatively, and an electron-deficient surface is charged positively.
Electrostatic charges are usually generated by friction between and/or separation of two dissimilar materials, at least one of which is a nonconductor or a poor conductor of electricity. The accumulated charge (stat
Nitrogen is the standard medium for contamination-free storage because it is relatively inert—it neither reacts with stored materials nor carries moisture—and because it can be isolated and purified relatively inexpensively.
Desiccator cabinets must be set up so that an appropriate flow of nitrogen forces out all moisture- and contamination-laden air. Because nitrogen has a lower specific gravity than air, it is introduced into the upper section of the desiccator; the he
