High Precision Solvent Delivery System

The pumps of the Smartline HPLC systems rely on the well proven Knauer solvent delivery technique which is known for pulse-free flow without the need for classic pulsation dampening. This is achieved through a combination of a highly precise mechanism and a “smart” drive control which Knauer simply terms “electronic residual pulsation dampening”. The technical design of Knauer’s Smartline instruments has further been optimized for the highest possible longevity of each component. Active piston backflushing, a standard feature in the Smartline Pump 1000, is a perfect example of this design philosophy. Smartline pumps can be easily upgraded at any time to form quaternary gradients, by adding a low pressure gradient module or by adding one or more pumps for high pressure gradients. All models are also available in a biocompatible version with titanium inlays. For further information see:
