  • Foreline Traps
    Molecular sieve traps containing type 13X synthetic zeolite effectively prevent oil backstreaming and trap water vapors at room temperature.Type 13X zeolite will adsorb molecules with critical diameters up to 10 angstrom. The sieve charge can be reactivated by baking out in place when a base vacuum
  • Vacuum Baking Process - What Is It And Why Would You Choose It For Your Application?
    High and ultra-high vacuum applications require parts that are free from volatile materials that would lead to contamination of the vacuum system. The vacuum baking process, also called bake-out, involves placing the parts into a chamber and heating them, under vacuum, to drive out gases and other
  • What Is A Virtual Leak And How Does It Affect Your Vacuum System?
    A virtual leak is a trapped volume of gas within a vacuum chamber that cannot be easily pumped out due to restrictions in the path connecting the trapped gas to the main chamber. Virtual leaks reference a leak that cannot be found during any activities or tests performed outside of the vacuum
  • Low Outgassing Accelerometers and Cables for Thermal Vacuum and Vibration Test Environments
    Exposure to the high vacuum level of a space environment induces material outgassing in ordinary accelerometers and cables. Any substance subjected to a vacuum has the potential to release trapped gasses. Contaminants from outgassing can condense onto nearby surfaces such as photo-optic devices
  • Outgassing And O-Rings
    Outgassing, also called offgassing, refers to the release of gas that has become trapped, frozen, dissolved, or absorbed in another material. Outgassing is a common problem when creating, or maintaining, a clean high-vacuum environment.
  • What Is A Vented Screw And Why Would You Need One?
    vacuum systems and enable faster, more efficient pump-down of HV, UHV, and EUV systems. These components allow the quick evacuation of trapped pockets of air and surface contaminants from blind-tapped holes.
  • Going Mobile - Ultrasound Monitoring Diesel Engines (.pdf)
    Ultrasound as a predictive maintenance tool is used successfully in many industrial applications in industries of all kinds. It is used as an inspection tool for detecting positive and negative pressure leaks such as those found in compressed air systems or vacuum pumps. Some industrial processes
  • Designing Atmospheric-Pressure Plasma Sources for Surface Engineering of Nanomaterials
    composition, it is expected that their dielectrophoretic (DEP). properties are also unique. cDEP is a technique developed to improve upon traditional. and insulator-based DEP devices by replacing embedded metal electrodes with fluid. electrode channels positioned alongside desired trapping locations
