Description
Vacuum controller VC 900 is a compact regulation unit for precise vacuum applications in the laboratory. It combines integrated pressure sensing with a two-point controlled valve, allowing the control unit to be positioned independently of the operating interface for flexible installation. Typical uses include rotary evaporation, distillation and central vacuum supply systems. Pneumatic hose connections are ID10 for process lines, ID10 for coolant and ID4 for inert gas. Permissible media and ambient temperature range is +10 to +40 °C. The instrument weighs 1,2 kg and measures 101 × 181 × 67 mm (W × H × D), making it easy to place on benches or within apparatus setups. Manufactured by KNF, the controller offers straightforward operation and reliable two-point regulation for reproducible vacuum levels. Suitable for both standalone and system-integrated vacuum management, it supports efficient solvent recovery and process control in chemical, pharmaceutical and analytical laboratories. Pack size is one piece.

Questions about Vacuum Control Unit VC 900
What is this article?
Vacuum Control Unit VC 900 is the article on this page. Luminix Health distributes KNF for laboratory use. It sits in Shakers, rockers & rotators, inside Stirring, shaking & mixing, in Lab instruments.
A shaker, rocker or rotator moves a rack, a plate or a bottle so the contents keep moving without a stirrer bar. Orbital, reciprocating and rocking motions are different. The platform, the load and the speed range are the specification.
Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
