This programmable syringe pump (ASP500) is an intelligent syringe pump with touchscreen and features a wide range of pumping flow rates at 0.5 µL/min - 60 mL/min. It has withdrawal and infusion working modes and can control and synchronize the pumps to allow uninterrupted liquid transferring.   The programmable function allows users to customize special infusion/withdrawal procedures thus meeting complex applications requirements, such as trigger dispense, periodic dispense and multiple-step infusion etc.  It is compatible with glass syringes with a volume range of 50µL to 25mL.  The syringe pump can be installed vertically or horizontally thus meeting versatility requirement when integrated with various analytical systems such as  micro-manipulators and stereotaxic instruments for biological  research applications.
