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:packing of HPLC columns at pressures up to 1000 bardelivery of supercritical fluids such as CO2 (with mounted pump head cooling device)metering against constant pressureThe 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 (A50751) has a 100 ml stainless steel pump head and can be operated at maximal 1000 bar back pressure for solvent delivery.Key featuresno electrical connection required, therefore suitable for operation in hazardous environmentscan be configured with four different pump heads (double piston design)easily changeable pump headspump heads can be equipped with eluent cooling or heating devicemaintenance-free pump drive
