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.
Rotary evaporators are advanced scientific instruments that are commonly used in chemical laboratories, processing laboratories and in research to facilitate fractionation. This separation process allows the solvents to be removed gently through evaporation and the precise control of the temperature.
Solvent recovery is the process of extracting target products from waste or by-product solvents generated during the manufacturing process. These chemicals can then be repurposed, reducing the need to produce or purchase new solvents, while eliminating a large amount of waste and removing potentially hazardous substances from the primary processed material
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.
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?
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.
