The LVS 105 T - 10 ef is the perfect partner for your rotary evaporator. It has been optimised for rotary evaporator application with an ultimate vacuum of 2 mbar and peak flow of 20 l/min, allowing non-volatiles such as DMF to be evaporated at 30°C. It combines a powerful built in chemical duty diaphragm vacuum pump with Ecoflex control principals. Heating of the pump heads allows a consistent clean vacuum without gas ballasting. The Ecoflex control continuously adjusts the pumping speed to match the vapour load of the process and allows the pump to exhibit single point control which reduces bumping and foaming whilst achieving increased evaporation rates. The built in digital vacuum controller allows easy adjustment of the desired vacuum level as well as the option to select common solvents from the built in solvent library. An inlet trap protects the pump from ingesting liquids and particles and an exhaust vapour condenser for optimal solvent recovery. Scope of delivery: chemical duty diaphragm pump in casing, inlet trap, exhaust condenser, Vacuum Controller 521 with ecoflex digital vacuum control

The perfect pump for your Rotary Evaporator whether you are working with high or low boiling point solvents - designed for chemical applications all contact parts are made of highly chemically resistant materials such as PTFE, PEEK, PVDF, PP and all glassware is plastic coated.
Free flow of 20 l/min. Vacuum to 2mbar. Corrosion resistant pump for use with acid / solvent vapours. Digital vacuum controller built in. Oil-free diaphragm technology. Compact and portable. Inlet and exhaust separators to collect condensates. Exhaust condenser for solvent recovery.
Very low vacuum allows easy evaporation of even non-volatile solvents - for example DMF at just 30°C
Ecoflex speed control system - the future for evaporation technology. The ecoflex control continuously adjusts the pumping speed to match the vapour load produced by the evaporation process, regardless of changes in other parameters. Boiling points can be selected via jog-dial from the internal solvent library, or can be automatically derived by the controller with sensitivity adjustable by the user. The Ecoflex control allows single point control which eliminates bumping / foaming allows faster evaporation and saves energy.
This pump has a compact design to save benchtop space and is designed for continuous running. It is for use with rotary evaporators vacuum ovens and vacuum concentrators.
Use tubing of 8mm inner diameter to connect this pump to vessels.
