The ASP12-1B syringe pump is the latest innovation from Longer Pump, combining advanced pumping methods with the highest accuracy.
This syringe pump can go down to flow rates as low as 0.0033 nL/min and stands out from the ASP11 series thanks to its broad syringe size compatibility (0.5 µL - 150 mL) and advanced continuous infuse/withdraw operating mode.
With its high-resolution touchscreen interface, compact vertical design, and exceptional flow stability, its versatility makes it an ideal choice for a wide range of applications.
This syringe pump can handle syringes from 0.5 µL to 150 mL.
Flow range 0.0033 nL/min-226.0 mL/min, accuracy ≤ ±0.35%.
