Technical highlights
Full control over your processes
Using the VACUU·SELECT controller is just like using a smartphone. The intuitive menu navigation via touch display is specifically designed for laboratory applications.
VACUU·SELECT offers predefined vacuum procedures for all common laboratory applications. For solvent evaporation, VACUU·SELECT automatically detects the boiling point and controls the vacuum process.
Of course, you can also individually configure and control applications and parameters. With the application editor you can simply create individual vacuum processes via drag and drop, then save them and then run them again and again.
NEW: VACUU·SELECT user management
The User management is a new extension for our vacuum controller VACUU·SELECT. For the first time, you can individually define access to different applications, functions and authorizations based on user groups.
➝ VACUU·SELECT user management
Developed for the chemistry lab
The VACUU·SELECT controller covers a wide range of applications. Chemically resistant materials and sealed display electronics protect the controller against corrosion. The touch display is designed in a way, that even when wearing thick / double safety gloves, the VACUU·SELECT still responds to your touch. The control panel can be taken off so that the pump can be placed in the base cabinet or in the fume hood, whilst you operate the controller comfortably from the lab bench.
Flexibility for your processes
VACUU·SELECT is available in various versions and fits every situation:
- The complete controller is fully equipped for operation on existing vacuum sources.
- The packages for fine vacuum control contain everything you need for control in the fine vacuum range down to 10-3 mbar.
- The powerful combination of our VARIO diaphragm pumps and the VACUU·SELECT controller offer particular benefits. The vacuum is controlled on demand via the motor speed. VARIO control is precise, highly efficient and whisper quiet.
- VACUU·SELECT is also available as a built-in version for laboratory furniture and industrial process systems.
- Integration into networks and data management systems works via appropriate connections and modern interfaces such as Modbus TCP and USB (RS-232 optional).
Vacuum control
VACUU·SELECT supports two vacuum control procedures. Classic 2-point control uses a solenoid valve with the VACUU·SELECT controller. Advanced VARIO control achieves unparalleled precision with motor speed control.
| Classic 2-point vacuum valve control | Pinpoint VARIO control via motor speed control |
 |  |
| Control by opening and closing a vacuum valve | Control via motor speed of the pump |
| Pump always runs at full speed | Pump speed adjusts in realtime ➝ Drastically reduced power consumption |
| Vacuum is maintained between the two valve switching points within the defined hysteresis range | Pinpoint vacuum ➝ Minimizes process times, saving as much as 30% compared to other control methods |
Evaporation processes: Automatic vapor pressure detection | Evaporation processes: Fully automatic evaporations at the touch of a button thanks to proven and reliable boiling pressure detection and continuous tracking through out the entire process duration ➝ Minimizes foaming and sample loss |
VARIO – Fully automatic evaporation at the touch of a button
When selecting the "Automatic Evaporation" mode, the VACUU·SELECT vacuum controller in combination with our VARIO pumps finds the boiling pressure of the solvent or even several boiling points of a solvent mixture fully automatically and continuously adjusts the vacuum to the process requirements - until the end of the process.

FAQ
How often should I adjust gauges and controllers?
Our gauges and controllers are designed for excellent long-term stability. You should perform an adjustment as required. We cannot give a general recommendation regarding the frequency. This is highly dependent on the media used in the process and the requirements for the measurement tolerances. The type of device also has an influence. Devices with capacitive sensors need to be calibrated less frequently than devices with Pirani sensors.
How often should gauges and controllers be calibrated?
There is neither a regulation nor a general recommendation in this regard. As with adjustment, the need for calibration depends on the process requirements, media used and type of device. Many customers decide on six-month or annual intervals.
Can I have my instrument calibrated at VACUUBRAND
Yes, we operate a measurement laboratory accredited by DAkkS (Deutsche Akkreditierungsstelle GmbH) as a calibration laboratory for vacuum measuring instruments. It is authorised to perform DAkkS-calibrations for vacuum measuring instruments in the range of 1300 to 10-3 mbar (abs.) and hand out DAkkS calibrating certificates.

What connections do the devices have and what materials are they made of?
The connections differ depending on the product. The information on this is precisely documented in the technical data and the operating manual. You can find these on the respective product page on our website or via our operating manual search.
How can I log and transfer data?
The DCP 3000 vacuum gauge and the VACUU·SELECT vacuum controller offer the option of data logging and data transfer via RS 232 interface. VACUU·SELECT additionally offers a USB connection as well as the option of network integration and communication via Modbus TCP. For exact information on connections and interfaces, please refer to the corresponding operating manuals. You can find them on the respective product page on our website or via our operating manual search.
Can the old CVC 3000 controller be replaced by the new VACUU·SELECT?
In general, you can simply replace the CVC 3000 with the VACUU·SELECT controller and continue to use your existing equipment. For pumping units with built-in controller, you should contact us in advance. We will then check whether the VACUU·SELECT fits into the housing of your existing pump.
