Vacuum Control Unit VC 900
Application: Rotary evaporation, Distillation, Multi-user vacuum systemEasy to use to control the vacuum applicationSeparate control unit with pressure sensors and two-step controlled valve to be placed independently from the operating unitVacuum controller can be operated with components from KNF and other producersPlease order the appropriate control cable for operating the N 920 G pump separately.
Vacuum Control Unit VCpro 601
Measures and displays vacuum pressure both graphically and digitally from 1100 to 1 mbar. Controlling the pressure can be done in real-time. The durable, chemically resistant sensor built into the VCpro 601 vacuum controller is a ceramic thick film hybrid. The sensor reading is gas independent and gives an absolute pressure.Precise vacuum control with timed ramp capabilityFully programmable modes to allow run repeatabilityIntuitive ICON-navigation of control screensConnectivity through LAN and RS232Built-in function for self-cleaning of diaphragm pumpSecurity levels for administrators and usersLog files on all pump activities for easy traceabilityHigh-Res display with dark and light screen modesDigital and analogue vacuum pressure displayAutomatic destillation controlCan be used with diaphragm or piston pumps from any manufacturerSuction / pressure connection: DN8 (6,35 mm ID) DN4 (3,2 mm ID)Inert Gas Port to Release Valve: DN4 (3,2 mm ID)
Vacuum Controller VACUU·SELECT
Fully equipped vacuum controller with capacitive, gas type-independent absolute pressure measurement using an alumina-ceramic diaphragm. While the base unit Vacuum Controller VACUU·SELECT®still requires a separate vacuum control valve as an accessory, there is the fully equipped Compact controller VACUU·SELECT®as two-point vacuum regulator with chemical suction line valve.With connected vacuum valve the VACUU·SELECT® automatically detects the boiling point during solvent evaporation and switches to two-point control mode. The graphical user interface offers predefined vacuum processes for all common laboratory applications. Applications, such as desired vacuum and other parameters can also be put together and controlled individually.Interactive, graphic touch display for easy operationTouchscreen display can be operated with safety glovesPredefined vacuum processes for reproducible results and time savings in the laboratoryFully automatic evaporations at the touch of a buttonEasy-to-use application editor for creating your own processesIntegrated help functionIntegrated ventilation valve also for inert gasEthernet/USB (Type A) interfaceEX approval: II 3/- G IIC T4 X Internal Atm. OnlyThe fully equipped basic unit without vacuum control valve can be positioned freely. A matching range of accessories offers everything for fitting into a variety of laboratory applications.Scope of delivery: Vacuum Controller VACUU·SELECTwith integrated ceramic vacuum sensor and venting valve, fold-out stand and power supply.Please order suction line valves separately.
