A customer approached Digivac to assist with vacuum control in an electron microscope. A vacuum within the microscope deeper than 20 Pascals (approx. 150 millitorr) causes visible degradation in the final image. The customer needed the ability to measure inside the chamber and precisely control the vacuum between 20 and 30 pascals while the electron microscope captures the image.

Trying to get to the primary drying end point can be time consuming and energy intensive whether you are going about it with a freeze dryer or a vacuum oven. However, there is a way to optimize this process so you know when your process is complete and all solvents like water are evaporated and product is dry. Wouldn’t it be time saving if you took the guess work out of your vacuum drying process?
Onboard Temperature and Vacuum Control for Most Vacuum Ovens: Vacuum ovens come with excellent temperature control mechanisms, but many are paired with manual isolation valves for vacuum. What this means is that, you can set your temperature digitally, but you have to turn valves to adjust the pressure in the chamber.
