Legato 270 Syringe Pump
Delivers full stroke for large syringes
The new Legato 270 syringe pump, from KD Scientific, Holliston, Mass, features an optimized user-configurable syringe mechanism designed to deliver a full volume in infuse and withdraw modes, whether small or large syringes are used. The reconfigurable mechanism allows the user to change the syringe clamping mechanism to hold from 0.5-µL up to 140-mL syringes. Two removable pins adjust the syringe mechanism to allow full stoke of the larger syringes. It includes a continuous push and pull pump. When used with check valves, the unit will draw fluid from a reservoir while the opposite side is dispensing fluid. After the user-selected volume is dispensed, the pump will automatically switch through the check valves and refill the empty syringes while dispensing from the other side.
