Years of continual innovation

Engineering and Design



The VAC Engineering Team is responsible for analysis, design, verification and validation of designs for all standard and new products as well as custom systems.  VAC has successfully completed countless custom designs over the years, including design to customer specifications, modifications of existing designs, prototype development, and completely new designs.  Recently, VAC Engineering worked closely with the VAC Sales staff to devise and bring to fruition our revolutionary, patented Genesis and NexGen inert gas cartridge purification systems.

VAC uses 2D and 3D drafting and modeling to support our standard and custom products.  VAC can provide stress analysis for determination of window and material thickness for standard and custom systems, as well as seismic analysis to UBC requirements using finite element analysis as required.  

VAC can provide special processes and testing as required, including among others, certified welding and inspection to ASME Boiler and Pressure Vessel Code Section IX and helium mass spectrometer leak testing to ASTM E498 and ASTM E499.

VAC maintains a longstanding membership in the American Glovebox Society (AGS), and VAC engineers have been active in developing and reviewing documents and publications of the AGS Standards Development Committee for many years.  Presently, the VAC Engineering staff has a combined total of almost 100 years of experience in the design of inert gas purification systems and gloveboxes.
