The ASP11-2AP Digital Lab Syringe Pump series from Longer Pump is engineered for laboratories and research facilities requiring precise fluid delivery.
In this dual low-flow version, the ASP11-2AP pump can go down to flow rates as low as 0.0009 nL/min, still with the same accuracy, high-resolution touchscreen interface, compact vertical design, and exceptional flow stability.
Available in both single (ASP11-1AP) and dual (ASP11-2AP) versions, its versatility makes it an ideal choice for a wide range of applications.
This syringe pump can handle syringes from 0.5 µL to 60 mL.
Flow range 0.0009 nL/min-23.597 mL/min, accuracy ≤ ±0.35%.
