Includes Vacuum and Pressure Regulators and Gauges - simple to adjust and monitor vacuum level and delivery pressure. Inlet Water Trap - float ball rises to seal off pump from accidental ingestion of water. Muffler quiets pump and filters discharge air. For use with dry or aqueous vapor applications only.

Standard duty, oil-free station is an economical , portable solution for aspiring , filtering or rinsing. Added accessories include 1.2 liter autoclavable, bleach resistant collection receiver , vacuum regulator & gauge, hydrophobic inline filter, automatic shut-off and vacuum regulator to simply use.

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 30⁰C. 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.
