In general, I knew that they use vacuum chamber when degassing is required between microfluidics or MEMS researchers.
How much level, pressure, is proper to theses works?
Of course, I used vacuum pump connecting with desicator.
Hi, I have never actually measured the pressure, but i can assure you that you will usually not need very low pressures. Check the following link: http://blogs.rsc.org/chipsandtips/2013/10/02/periodic-degassing-of-pdms-to-create-a-perfect-bubble-free-sample/
For PDMS, less than 0.005 Mpa is suggested and keep for 20min or more time.
For degassing the PDMS, it's also important to use the shutter of the desicator to allow some air in during the process, which will cause many large bubbles on the surface to explode. So low level or vacuum is only one factor.
By the way, PDMS is much easier than some of the resins in terms of degassing, because latter only allow you
