Vacuum system one minute run down

On request I made a VERY short vid lolz trying to show my personal preference for vacuum system. So far this configuration has been trouble free and allows a pull down recorded at the sensor of one micron. The sensor if placed closer to the puddle would likely show a slightly higher reading depending on rates of evaporation. However once pulled down into mean free path flow vacuum ranges the vacuum throughout the entire path would be nearly the same. There is no perfect vacuum that we can achieve and the placement is important to me but design wise my primary objective was to protect a very expensive Pyrani sensor.
