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.

Some materials are super sensitive to temperature making it more difficult to vacuum dry . It is crucial to make sure that the temperature remains constant as it can end in a loss of materials if an error were to happen. Not being able to completely control your vacuum can result in making you restart the process back to square one.
Many people come to find out that they have problems when it comes to vacuuming powder. Especially drying fine powder that tends to get puffed up and pulled into the vacuum pump flooding it. With the pumps flooded this leads to an unfortunate problem, one you end up losing the powders you’re trying dry and two it isn’t the best for your pump either.
The precise vacuum control of the SNAP is driven by the integrated patent-pending Dinamo valve with delivers both proportional vacuum control as well as proportional bleed control and supports high flow with KF25 orifices so its ideal for your larger cubic foot ovens. The internal sensor is isolated from your vacuum drying process so that the sensor won’t get contaminated and vapors will not disrupt your readings. The SNAP is designed for highly precise control and is ideal for automating vacuum oven control in the 1 torr to 775 torr range. With the SNAP you are able to Automate your vacuum control through the click of a button.
Don’t Forget the Grease How many connections do you see? When putting together distillation systems that function under vacuum, you cannot forget to use vacuum grease on all the connections or leaks will happen. Tracking down a leak after everything is set-up just leads to frustration and wastes time! Important Considerations for Set-Up All the glass parts should be handled gently, washed, and dry before loading. A good quality vacuum grease should be applied to each joint and connection before installation that includes all glass and vacuum fitting interfaces. Lastly, check the vacuum hoses and pump for proper function. What
