Ultra High Vacuum Chamber Manufacturers

Applied Vacuum facility
Applied vacuum technology, Inc. was incorporated in 1989. Our 43,000 sq. ft. facility is located in Waconia, MN, a suburb of the Twin Cities.


Applied Vacuum Technology was founded by a former manager of Physical Electronics, who directed fabrication of vacuum chambers and components for PHI's surface analysis instruments. Today AVT continues with our primary focus in custom fabrication of stainless components and chambers for high and ultra-high vacuum applications. 

Our staff is comprised of a variety of backgrounds including physics, materials science, non-destructive testing, mechanical engineering and business administration. AVT has extensive design and manufacturing experience for surface science instruments, semiconductor processing equipment, vacuum coating systems, and other vacuum equipment.   


AVT supplies custom components, chambers and assemblies for a variety of industries that utilize vacuum equipment and process. Research markets include Advanced Materials, Atomic Science, Particle Physics, Energy, Biomedical and other disciplines employing UHV systems. Commercial markets include Semiconductor Processing, LED, Microelectronics, Decorative and Performance Coatings, Aerospace, and others. 

We also have engineering and manufacturing resources available from our parent company, Anderson Dahlen, which has over 40 years of custom stainless fabrication for food processing, pharmaceutical, chemical, nuclear and other industries.

AVT's core competencies involve machining and welding of stainless steel with careful utilization of Ultra-high vacuum (UHV) fabrication techniques. We are keenly aware of material choices and preparation techniques, and their impact on end product vacuum performance. AVT stocks an extensive array of ESR (Electro-slag remelt), VAR (Vacuum-arc remelt) and standard grade low carbon stainless steels; as well as a number of other alloys commonly used for vacuum components and chambers.  We have experienced resources for special processing of raw material and finished products such as vacuum heat treating, annealing, stress relieving, dehydrogenation, passivation, electro-polishing and other techniques commonly required for ultra-high vacuum ad well as XHV (Extreme high vacuum) applications.
