  • Fluid Feedthroughs
    MDC fluid feedthroughs are designed for the transmission of gasses or coolants into high and ultrahigh vacuum environments. They are constructed from 300 series stainless steel and available with single or dual tube configurations. All feedthrough versions are fitted with 1/4 inch tubes
  • When Wire Feedthroughs Make Sense
    Engineers who work with pressure and vacuum chambers usually reach for off-the-shelf sealed bulkhead connectors when they need to pass power and signal wires through the chamber wall. And while these connectors may seem like the best or only way to breach the chamber walls, they can actually drive
  • Meeting Feedthrough Challenges on the A-3 Test Stand
    The purpose of this paper is to share the experience and knowledge that engineers at NASA and Douglas Electrical have gained regarding the specification of hermetic seals and feedthroughs used in engine test stand vacuum chamber applications. This paper looks specifically at the experience
  • The six challenges of specifying and procuring hermetic feedthroughs for space simulation
    The purpose of this white paper is to share the details and knowledge that engineers at Douglas Electrical have gained over the years regarding the specification and sourcing of hermetic seals and feedthroughs used in space simulation vacuum chamber applications. Having worked with most major space
  • Electrical Feedthroughs
    In the vacuum components industry there can be few more specialized technologies than the production of ceramic-to-metal seals. Ceramic-to-metal seals, the bonding of metals to ceramics are fundamental to the manufacture of thousands of components in applications where electricity and optics must
  • Motion Introduction
    MDC motion products are vacuum compatible precision instruments ideal for demanding in-vacuum sample handling applications. The motion feedthrough product line presented in this section is divided into three basic categories including rotary, linear and multi-motion instruments. Each product
  • Bell Jars Systems
    MDC stainless steel bell jars are designed for use with MDC baseplates, base wells and feedthrough collars. A dovetail groove in the jar's base flange holds a Viton® elastomer gasket, which makes the vacuum seal with one of the forementioned components. All stainless steel bell jars are fitted with a
  • Quick Disconnects
    MDC Quick-Disconnects provide a fast and convenient method for coupling and uncoupling metal and glass tubing. They can be welded, brazed, or soldered to flanges, manifolds, chambers, and other vacuum equipment. Quick-Disconnects are ideal for mounting ion gauges, thermocouple gauges, special test
