What you are seeing here is our crystal clear acrylic vacuum chamber, hinged side door with clamps. In addition, our client has asked us to add 1. A quantity of two high power feedthroughs on the top right wall, 2. An 8-pin power connector, and 3. a multi-pin feed through. These vacuum feedthroughs enable the routing of electrical power and signals from the outside of the chamber into the inside of the chamber without disrupting the vacuum.

The Feedthroughs are fully fastened to the wall and hermetically sealed by an O-Ring or Vacuum epoxy. The advantage is that the electronics can be connected and a vacuum can be pulled without leakage.

If we open the door, we can see the power cables perturbing into the inside of the chamber. Here, our client is able to connect these wires to their electrical device, close the door, and pull a vacuum. Because the walls are made of cast transparent acrylic, the electrical components inside the chamber fully visible during the test.

Did you know that we carry a many more products?

Our clients prefer to work with us because we are Experts in Custom Fabrication (especially Polymer Fabrication). What are you building? Take a look at the links below and discover some of the cool things we make.

Stainless Steel Vacuum Chambers
Stainless Steel Vacuum Chambers are vacuum chambers made from stainless steel. The advantages of a Stainless Steel Vacuum Chamber are High Vacuum and a Wide Temperature Range of applications.
Micro-D Vacuum Feedthroughs
Micro D Vacuum Feedthroughs are Micro D connectors rated for vacuum and are generally installed on the vacuum chamber wall. You can then connect from the outside to the inside of your chamber.
Our Work: Bubble Leak Testing System with a Dry off Sink used for Leak Testing Large Bags
How do you leak test Large Food Bags? This is the same question a Large Food and Beverage Processor had asked themselves because they had need for a bubble leak testing system which could be used to detect presence of leaks in their large bags. Their requirements were to test several sized bags with the largest bag being 24 inches Wide by 12 inch Deep by 9 inches High. In addition to the bubble leak testing system, they also needed a way to dry the bags after the test.
