Opaque Vacuum Chamber

Opaque Vacuum Chamber
An acrylic vacuum chamber does not always need to be transparent, there are instances when a vacuum chamber needs to be made from acrylic and that acrylic also needs to be fully opaque where no light can pass through.

A customer of ours reached out to us to see if it was possible to design and built a vacuum chamber that is made from polymers but is also opaque. They were testing some light sensitive equipment where it was critical that the amount of light coming in and going out was strictly controlled for. When they reached out to us, we knew that opaque acrylic existed, but we only knew about thinner acrylic panels, those which were about 0.25 inch thick. Acrylic this thin cannot be used for vacuum applications because the forces applied to the wall at 15 psi are large and will risk beveling, bending, and damaging the walls at full vacuum. Imagine a vacuum chamber which that is 10-inch by 10-inch and at 15 psi of vacuum, the force applied to the wall due to pressure differential equals the area times the pressure which is 1500 lbs. That is the weight of a car being applied to a 0.25-inch-thick acrylic panel, barely enough. So we reached out to our supplier to see if they had something thicker, and they did.

What you are looking at is an opaque acrylic vacuum chamber that is 10 inch Wide, 10 inch High, by 20 inch Deep. This is a hinged door, front loading chamber where the door fully swings open towards the front right allowing for easy chamber loading. The door comes with two hinges, two clamps, and one lid handle. Another customization made to this chamber is a 15 pin D-SUB (subminiature D) Connector on the Left Wall at center. This chamber can be easily placed onto a table top and operated as a bench top unit. Looking for a vacuum chamber? Let us know how we can help you. Contact us.

Force Decay Leak Testing Systems
Force Decay Leak Testing Systems are instruments that detect and quantify leaks in a test specimen through measuring the drop in force an inflated specimen applied onto a pressure transducer. The specimen is placed into a vacuum chamber, a vacuum is pulled, and the test sample inflates. As the test sample inflates, it applied a specific force onto the force transducer. This force is measured and recorded over time. If a leak exists, the specimen will deflate and lose pressure, as a result, the force it applies onto the force transducer will decrease. This in turn will enable for detection and quantification of a leak in the specimen.
Viewport Vacuum Feedthroughs
Viewports Vacuum Feedthroughs are windows that enable you to look into the inside of your vacuum chamber. If you are using a metallic vacuum chamber with a metallic lid, you will not be able to view the interior of your vacuum chamber unless you have a viewport. Viewports also enable a different electromagnetic spectrum of light to passthroughs.
Our Work: Vacuum Storage of Chemicals that interact with Stainless Steel
There are countless chemicals and metals that interact with Steel or Stainless Steel. According to our investigation, Gallium, Cadmium, Beryllium, and Zinc are some examples of materials which will interact with Steel or Stainless Steel during vacuum Storage.

Bubble Leak Testing or Bubble Emission Testing is a procedure where leaks are visually detected and located through the emission of bubbles while the test specimen is submerged in water. In this article, we will talk about using an acrylic vacuum box as a leak detection device. We are also going to talk about the advantage, disadvantage, and the bubble leak emission test procedures.
