Electrical feedthroughs move power, signal, and temperature data across the wall of a vacuum chamber without breaking vacuum integrity. Selecting the right one comes down to four considerations: What are you transferring (i.e., power, a shielded signal, multiple conductors, or temperature data)? What voltage and current does it need to carry? How many pins or…
Introduction: Why Vacuum Jacketed Hoses Matter In applications where temperature control is critical, even small amounts of heat transfer can have a measurable impact on system performance. For cryogenic systems, unwanted heat ingress leads to increased boil-off, higher operating costs, and reduced efficiency. In high-temperature processes, heat loss can affect consistency, energy usage, and overall…
Introduction Designing a vacuum system rarely ends at the chamber wall. After pumps, gauges, and instrumentation are specified, the practical challenge becomes integration—routing lines through confined spaces, maintaining centerline alignment, and resolving the misalignment that inevitably emerges between concept and installation. Vacuum fittings enable that integration. They translate layout intent into physical connections, accommodating…
ISO-KF (ISO-QF) flanges are a standard choice for vacuum systems requiring quick assembly and repeatable sealing. Despite their widespread use, KF flange sizing can be a source of confusion during system design and component selection. This article clarifies how KF flange sizes are defined, what the nominal size represents, and how to select the correct…
Dirty, particle-rich environments such as those found in vacuum coating and deposition systems frequently encounter problems with buildup and restricted conductance when regulating flow with isolation valves. Traditional industry valve solutions offer bulky designs without addressing the design features contributing to these issues. At ANCORP, we’ve designed a high conductance ball valve to address these…
Choosing the Right Feedthrough Connection for Your Needs In vacuum systems, selecting the appropriate feedthrough is crucial to achieving reliable connections and maintaining vacuum integrity while transferring power, fluids, gasses, or motion. Each of these transfers requires specialized vacuum feedthroughs, which can be daunting to select with all the available options. This guide will help…
No stranger to invention, ANCORP welcomes a second round of patent-protected valve developments to our high vacuum ball valve line. Our latest development, Heat-Thru technology, improves heating efficiency for coating, etching, and abatement systems by eliminating the cold spot commonly found in balls of heated ball valves. Heat-Thru technology is now available as an option…
Wire Seal flanges offer versatile solutions in ultra-high vacuum (UHV) settings, serving as reliable connections for fittings, valves, and instrumentation. Capable of operating across the same temperature and pressure ranges as CF flanges, Wire Seal flanges are particularly useful when tube dimensions exceed those of standard CF connections. The following guide is an installation manual…
At ANCORP, we pride ourselves on producing the industry’s leading high vacuum ball valve. Though uniquely different in its stem stabilization and valve lifetime, the ANCORP ball valve is similar to any precision instrument in its need for maintenance. It’s important to understand that even the best valves have wearable internal components that need periodic…
