What would the moistue content be inside a cylinder where a vacuum is pulled 25-30HG? Could such a cylinder be used to "dry out" something?
jerich1000 said:What does pulled 25-30 HG. You mean pulled from that to zero? Or pulled from something else to that? If pulled to zero, then the moisture content would be zero, as the cylinder would contain a vacuum. Please clarify.

stewartcs said:You'll need to keep the lid of the container closed in order to keep the vacuum.
As soon as you open the lid, the rods will start to absorb moisture again (I don't know at what rate) so you'll have put them in the device, close the device, dry them by drawing a vacuum, equalize the pressure with atmospheric, open the device, take one out, close the device again and draw the vacuum again to keep them dry.
You may need to purge the container with dry Nitrogen to help speed up the drying process.

stryped said:So by saying equalizing the pressure to atmospheric I should add some sort of pressure relief valve to depress before opening?
The only time the lid would be open would be when a rod has to be used.
My only problem is I don't know how well a small vacuum pump would remove moisture. I sometimes use an old refrigerator pump. I would liek to have some sort of msall pump I could mount on the container.
stewartcs said:Yes you would need some type of valve to equalize the pressure. You most likely will not be able to even open the lid without equalizing the pressure (there would be a very large net force from the atmospheric pressure acting on the lid).
However, using desiccant like Mech_Engineer suggested may certainly be the simpler and cheaper route.

Unless you just want to experiment with vacuum ??

Moisture content is the amount of water or other liquid present in a substance or material. It is typically measured as a percentage of the total weight of the substance.
The most common method for measuring moisture content in a vacuum is by using a moisture analyzer, which uses heat and weight measurements to determine the amount of water present in the substance.
Vacuum pressure can significantly affect the moisture content inside a cylinder. As the vacuum pressure increases, the moisture content decreases because the pressure change causes the water to evaporate more quickly.
The ideal moisture content for a substance inside a vacuum depends on the specific substance and its intended use. In general, a lower moisture content is desirable to prevent corrosion, mold growth, and other forms of degradation.
The moisture content inside a vacuum can have a significant impact on the overall environment. Excess moisture can lead to the growth of microorganisms, rust and corrosion, and other forms of damage. Maintaining proper moisture content is crucial for preserving the integrity of the vacuum and the substances inside it.
