Custom Vacuum Chambers

Guaranteed to Meet Your Special Requirements.
We can assist you with chamber concept, application, engineering, and design.
We work from your rough sketches, and prepare complete production drawings on our 3D CAD system using the latest version of SolidWorks. The cheapest chamber may not be the least expensive. To insure you receive exactly what you need, we provide you with complete production drawings for your review and written approval, before fabrication begins. Whichever vendor you choose, we strongly recommend production prints be sent to you for final approval prior to manufacturing. Approved prints minimize the possibility of design and/or manufacturing errors.

Our many years of experience permit us to offer you the following advantages:
Complete Production Drawings -- Prepared and Submitted for Customer -- Approval Before Fabrication Starts.

Standard Performance
Certification and Documentation

Every chamber shipped is certified:
*To be leak-free, leak-checked with a helium mass spectrometer to a sensitivity of
  2 x 10-10 mbar l/s. A certificate of compliance is supplied.
*Tolerances according ISO 2768-1m
*Port alignment accurate within ±1°.
*Fabricated from type 304(L) stainless steel. Options for 316L or 316LN (ESR).

Performance Options

At your option and request, we can perform, certify, and document:
*Qualification of ultimate base pressures measured < 10-10 mbar, achieved with
  the system in our facility. Certification of bakeout and pumping techniques
  employed to achieve specified pressure.
*RGA partial pressure analysis < 10-13 mbar from 0 to 200 AMU.
*Choice of the conditions under which the system is shipped, e.g., blanked off,
  under vacuum, bagged with dry nitrogen or other gas of your choice, or a
  combination of the preceding.
*Choice of materials used in fabrication. 316L, 316LN(ESR), Alumimum, Titanium, etc.
*Chemical and mechanical processes used to prepare systems and surfaces, such as
  passivation, electro-polishing, mechanical polishing (up to a #2-lap finish), or
  chemical removal of carbon and/or hydrogen from the surface.
