  • Recirculating inert gas purification apparatus used with gloveboxes, gloveboxes incorporating the same and methods of using the same
    Patent number: 10549004
    Abstract: An apparatus that may entirely be contained in a glovebox for the removal of at least one contaminant from an inert atmosphere. The apparatus includes a body, a media in the body for the removal of at least one of the contaminants from the inert atmosphere flowing through the media, a fan for causing the inert atmosphere to flow through the media and body, and a motor for driving the fan. The apparatus may be provided in combination with a glovebox. A method of purification of the inert atmosphere using such an apparatus is also provided.

  • Vacuum oven, system incorporating the same and method of using the same
    Patent number: 6914218
    Abstract: A vacuum oven for decontaminating items, a system incorporating multiple such vacuum ovens and a method of operating such system are provided. The ovens are portable. They can have a vacuum drawn in them and can be heated by being coupled to a vacuum and a power source, respectively at a first location and then be decoupled from the vacuum and power sources and moved to a second location such as a glove box or clean room while still maintaining a vacuum.

  • Electromagnetic interference filter
    Patent number: 6816033
    Abstract: An electromagnetic filter has a pair of solder-in filters assembled together outside of a filter housing, inserted into, and soldered to the filter housing. The solder-in filters have a metal casing and a capacitor encapsulated within the metal casing and attached to the metal casing. A glass hermetic seal on one end of the solder-in filters reduces the risk of moisture entering the filter during the testing process and adversely affecting the electrical properties of the filter.
