Degassing/Vacuum Chambers
Hello all!
I work at a small CM in the midwest and I’m looking into degassing chambers for small scale R&D and QC use. Our production tanks are not fitted with vacuums and so therefore it’s difficult to tell if a formula is clear or hazy, if viscosity is accurate, etc. due to aeration.
I’ve seen resin art videos online where people use these chambers to remove air bubbles. The resin is much lower viscosity than some of the gels we produce, which is where I’m hesitating. The product I’m looking at is linked below:
Any thoughts or experience? We’d only need to deaerate, at max, 500 - 600g worth of material at a time. QC would be doing even less.
Thanks in advance!

Depending on the viscosity of your substance, degassing with a basic vacuum chamber might be impractical or impossible. The higher your viscosity, the longer degassing will take, and there will be a point where the material will simply fail to degas. The best practice for degassing high-viscosity fluids is to use a vacuum oven such that you can heat the material as well as apply vacuum, as the vast majority of fluids become less viscous when heated.
Vacuum ovens are significantly more expensive than basic vacuum chambers, but for R&D scale you can get small, simple vacuum ovens for a bit over $1000.

If you need something to be both in a vacuum and heated, you could launch it into the infinite void of space in the general direction of the sun, or you could put it in a vacuum oven. We think … Continue reading
