The Hibar B series Rotary Valve precision dispensing pumps are ideally suitable for higher viscosity applications that require dispensing volume of 50 µl to 20 ml per shot. These pumps provide extremely high dispensing accuracies of ±0.2% or better. The hibar pumps combine this proven dispensing technology with state-of-the-art servomotor drives to provide precise, programmable control over the dispense volume and speeds. Recipes and parameters such as acceleration, fill volume and fill speed can be downloaded to the pump with ease with a simple serial connection.
