Liquid and Gas Vacuum Feedthroughs

A Liquid or Gas Vacuum Feedthrough will enable you to run liquid or gas into the vacuum chamber without compromising the vacuum. You may need either heat or cool your device during vacuum operations. One way to do this is to run a coolant line from the outside to the inside of the vacuum chamber and then connect that line to the specimen. All this can be done while the specimen is under vacuum and while the coolant line is flowing and cooling your specimen without interfering with the vacuum performance. You can have as many lines as space allows, the diameter can range from 0.0625 in and up. What you are seeing in the image are 30 tubes each with a 2-millimeter diameter being run from the outside towards the inside of the vacuum chamber – the other image is a simple 1/4 inch OD Swagelok gas feedthrough.
