FQA as below:

Q1. Can the drying oven handle a slight vacuum? 600 Torr = 80kPa = 11.6 psi = 0.8 atm?

The vacuum oven can , The vacuum degree can reach 80KPA.

Q2. Where in the interior chambers are the gas input and gas outlet/vacuum located? I am checking to see if they are across the chamber from each other for good gas flow for drying.
