Vacuum Measurements

MDC provides a basic but proven assortment of the most commonly used vacuum gauge tubes. Thermocouple and ionization gauge tubes designed to meet the rigorous demands of most vacuum applications are offered for replacement of Granville-Phillips, Perkin-Elmer and Varian style gauge tubes. In addition, a visual dial Bourdon gauge provides a quick method of estimating vacuum levels. 

Introduction to Vacuum Measurement

MDC offers a wide selection of optical quality windows. These hermetic viewports are available in various window materials including type 7056-glass, sapphire and fused quartz. They are constructed with vacuum grade materials using the latest in glass-to-metal and ceramic-to-metal bonding technology.

Electrical and Fluid Feedthroughs

Electrical feedthroughs are manufactured by Insulator Seal, MDC’s ceramic-to-metal seal division located in Sarasota, Florida. Insulator Seal bonds high purity alumina ceramics with low expansion metals to produce the industry’s most reliable hermetic seals. The electrical feedthroughs produced with this bonding technology are required in most any vacuum system and provide the means of delivering or transmitting high current or voltage as well as instrumentation signals in and out of vacuum systems. Non-electrical fluid feedthroughs for conventional and liquid nitrogen cooling are also offered in this section of the catalog. 

Motion and Manipulation

MDC has assembled a comprehensive selection of precision instruments ideally suited for the manipulation of samples located inside a vacuum chamber. Rotary, linear, wobble and combined motion instruments are available for precise manipulation of samples. Motion instruments are driven with fine-pitch micrometer lead screws and constructed with a welded bellows actuator for maximum reliability and UHV compatibility. Also available are multiple-axis xyz-motion stages, rotatableaxis and axial-lift stages, load-lock systems, magnetic transporters and patented sample handling systems. Automation via motorization is available for most of the motion instruments in this section.

Thin Film Deposition

Electron-beam evaporation transforms the most basic of elements into valuable thin film coatings. MDC’s e-Vap® product line is dedicated to the advancement of electronbeam technology to better serve vacuumcoating science and industry. Miniature and turnkey production evaporation sources are available to meet the needs of any vacuum coating application. Leading edge electronics, high frequency switching power supplies, source control modules and programmable beam sweeps provide the finest controls over the process of thin film
deposition.

Chambers

MDC offers standard vacuum chambers for basic research and laboratory vacuum applications. Stainless steel bell jars, feedthrough collars, baseplates and base wells with elastomer seal interfaces are ideally suited for most high vacuum applications. Standard surface science chambers fitted with Del-Seal™ CF metal seal flanges are available for demanding UHV surface analysis applications.
