with DC motorperistalticlaboratory

Harvard Apparatus’ 66 and 77 Peristaltic Pumps provide highly accurate and repeatable flow rates and are extremely easy to use. High Accuracy These pumps have the same high quality micro-stepping motor that creates the legendary accuracy of Harvard Apparatus’ Syringe Pumps. Other peristaltic pumps have less accurate DC motors. No other peristaltic pump offers this quality of basic motor control. Additional accuracy features include ramped deceleration as the end-point is approached and a ‘slurping’ feature to prevent end of dispense dripping. As the end-point approaches, the pump slows to drop-by-drop delivery. As the last drop required is delivered, the pump immediately reverses one step and slurps back preventing unintended fluid delivery. Only these Harvard Apparatus innovations enable accuracy approaching that of a syringe pump from a peristaltic pump.
