Toxicology Experiments performed with Acrylic Pressure and Vacuum Chamber

There are several occasions when you will have to perform toxicology experimentation on your engineered systems. One of them is on aerospace components and subassemblies intended to be installed on spaceships and airplanes. During spaceflight, humans exhale carbon monoxide and other gasses which can become deadly if the concentration reaches above 5%. There are also other deadly gasses which also accumulate and must be accounted for in order to ensure safe flight.

Our client, who performs toxicology experiments that aid spaceflight missions contact us to discuss how our regular vacuum chambers could be modified in order to fit their specific need. They did not tell us exactly what experiments they were performing. However, they asked us to customize our standard vacuum chamber.

What you are looking at is our vacuum chamber that has a 5 psi pressure option with a 10 psi safety relief valve which will pop open if the pressure exceeds more than 10 psi (gauge pressure) inside the chamber. The chamber dimensions are 14 inch cube. In order to modify our acrylic vacuum chamber to be able to withstand a max of 10 psi overpressure, we had to install thumb screws that would hold the lid compressed against the O-Ring in order to keep an air tight seal.

In addition to the overpressure option, we also added two NW50 / KF50 Vacuum Ports on the rear wall. These vacuum ports are blanked off by an aluminum blank and a NW50 centering ring. This blank was removed and our client installed their own NW50 connection to their ports. On the Right wall we provided our client with two tube liquid or gas feedthroughs for the 1/4 inch tube OD. These liquid/gas vacuum feedthroughs will allow our client to run liquid or gas into the vacuum chamber without compromising the vacuum. On the Left wall, we added two gas or liquid vacuum feedthroughs for the 1/8 inch tube Outside Diameter. Also, on the left wall is a 1/2 NPT female port that was blanked off with a plug and later used by our customer to add temperature measuring device into their vacuum chamber.

Vacuum Oven Systems
Vacuum Ovens are vacuum chambers and ovens combined in one system. Vacuum ovens are necessary during processes which require the specimen to be subjected to a hypobaric and hyperthermal environment. Our Vacuum Oven Systems enable to you run a complete vacuum vs time and temperature vs time profile. We also carry portable vacuum oven systems and custom vacuum oven systems.
Belt Drive Rotary Vane Vacuum Pumps
A Belt Drive Rotary Vane Pump is almost identical to a Direct Drive Rotary Vane Pump. The only difference between the two is that the belt drive Rotary Vane Vacuum Pump is driven by a belt. There are several advantages why a belt drive vacuum pump would be preferable. One of these reasons is that the belt drive Rotary Vane Vacuum Pump runs at a slower RPM therefore the temperature created is lower, the wear and tear is less, and the overall lifetime of the pump is longer. The disadvantages are a lower CFM and performance.
Our Work: Modified 14 inch Cube Vacuum Chamber for Degassing
This custom job was a modification to our standard acrylic vacuum chambers. When it comes to working with the Us Military, they want all specs to be met 110% and they want it yesterday. The military does not mess around which is why they came to us since we know how important it is to meet specs and ship fast.

In the article we are going to cover rotary vane vacuum pumps. We will touch upon how they work, what they are used for, when to utilize a rotary vane vacuum pump, its advantages and disadvantages. Perhaps you have noticed that rotary vane vacuum pumps come in all shapes and sizes. On one website, the vacuum pump is less than a $100; on another website you see a vacuum pump quotes at $10,000. I would imagine that you immediately ask yourself what the deal here is.
