The Smartline Pneumatic Pump 1950, powered by compressed air, has been designed for solvent delivery in process chemistry, column packing or preparative chromatography. Application areas:
The delivery flow rate depends on the compressed air supply and the back pressure of the column or system. Maximum delivery flow rate can be reached at minimum liquid pressure (below 1 bar). The minimum liquid flow rate (approx. 5 ml/min) is achieved at highest back pressure. The Smartline Pneumatic Pump 1950 (A50781) has a 1000 ml stainless steel pump head and can be operated at maximal 50 bar back pressure for solvent delivery.
