"This pump can control very good pressure when reducing it or bringing it back to atmospheric pressure. It has multiple options, you can create your programs where you set the pressure and the time, and it gives you graphs on the way pressure evolves over time. It is actually fun to work with. Also, it can keep the pressure you set with high precision. What I noticed however is that when setting a large time for the pressure to go down, it actually drops too quickly, so this feature can still have some improvement. It is easy to use, and very intuitive."

"Best diaphragm pump in the world. No down time in 14 years. Effective and economical system."
VACUUBRAND® VARIO®-control chemistry diaphragm pumps, combine the intuitive VACUU·SELECT® touch screen controller with variable motor speed. The VACUU·SELECT controller simpifies your work and allows VARIO® select chemistry diaphragm pumps to deliver unparalleled precision. Select from a set of predefined applications, modify an existing process or create your own using the drag-and-drop editor. The pumps run whisper-quiet and respond to demand in real time by adjusting pumping speeds to match process conditions. VACUUBRAND chemistry diaphragm pumps deliver exceptional performance in a durable and low-maintenance design. Chemically-resistant wetted materials allow the pump to be used with aggressive gases and vapors. The oil-free design contributes to clean processes and products as well as eliminating the time and expense related to oil-changes. The inlet separator prevents particles and liquid droplets from entering the pump, extending pump life. The exhaust vapor condenser allows for nearly 100% solvent recovery.
