Since the remote control unit with the control device of the pumping station is wirelessly in control connection, while a temporary opening of the trigger is not required. Rather, the pumping station can be operated with sufficient distance from outside the trigger without the laboratory personnel having to expose themselves to special risks.
- the pumping station according to the invention has a console for receiving or storing the operating unit. If the operating unit is located on the console, the pumping station can be operated as usual with the control unit located on the console. In contrast, the pumping process requires a safety distance of the operating personnel, the pumping station can be operated by means of remote control with the pumping station also wirelessly in control connection remote control unit with distance. Thus, it is only the pumping station according to the invention that it can be operated either directly with the operating unit located on the console or can also be operated wirelessly with distance by means of the remote control unit. It is a particular advantage of the pumping station according to the invention that the console also has a contact system for the power supply to the charging system for the batteries located in the operating unit.
- the batteries in the operating unit can always be charged if the pumping station is operated directly via the control unit located in the console. In this way, it is ensured that sufficient power is always available in the operating unit if the pumping operation requires a distance between the pumping station on the one hand and the remote control unit on the other hand and the pumping station is to be wirelessly controlled by remote control unit even at a distance.
- the pumping station has at least one display for displaying the process parameters, which display is connected to the pumping station via wireless data transmission. Since in the pumping station according to the invention on the remote control unit, the current process values can be both read and changed, the pumping station according to the invention can also be conveniently monitor and control distance from outside the trigger. It is particularly advantageous if an automatic boiling point detection can be displayed on the remote control unit.
- the wireless data transmission and / or control connection can be for example an ultrasound or an infrared connection.
- a radio link is preferred. Since even such a wireless connection has only a more or less limited radius of action, and since an accidental exceeding of this radius of action there is a risk that the rotary evaporator out of control, it is useful if the remote control unit has a visual and / or audible warning, which triggers an alarm as soon as the remote control unit is out of the functional area of the wireless data transmission and / or control connection.
- the remote control unit In order to be able to operate the remote control unit in a simple manner manually, it is expedient for the remote control unit to have at least one operating knob as operating element which is intended for selecting the control functions and / or for changing the process parameters. Additionally or alternatively, the remote control unit may have a touch screen as a control element, which is also intended for selecting the control functions and / or for changing the process parameters. On this touch screen, the operation can be done by directly tapping the buttons shown on the display. In this case, a preferred embodiment provides that the touch screen is simultaneously configured as a display for displaying the process parameters. It when the remote control unit has at least one control knob and at least one touch screen, which are in operative connection with each other is particularly advantageous.
- the pressure in the rotary evaporator preferably adjusted via the adjustable at the remote engine speed of the pump provided in the pumping vacuum pump to adjust the boiling point exactly and avoid foaming of the medium to achieve a reduction in noise and to optimize the life of the pumping can.
- control device In order to rule out incorrect operation, it is advantageous if special main functions of the control device can only be selected when the pumping station is at a standstill, while process-important parameters can also be changed during operation.
- a preferred embodiment according to the invention provides that individual functions of the control device are arranged in a menu structure and that by means of the at least one operating element, the scrolling through the individual menus.
