BASi syringe pumps are modular systems that consist of a syringe pump drive and a drive controller. Two controller configurations are available for use with BASi Syringe Pump Drives: the Worker and the Hive. The Worker Controller offers easy setup and great mobility. The Hive Controller provides the capability to independently control up to four syringe pumps from one controller. This makes it not only flexible and powerful, but also very cost-effective. Syringe drives sold separately.
