The ASP12-XB multichannel syringe pump represents Longer Pump’s newest innovation, integrating advanced pumping technology with exceptional precision. It achieves flow rates as low as 0.0033 nL/min and distinguishes itself from the ASP11 series through its wide syringe size compatibility (0.5 µL–10 mL) and advanced continuous infuse/withdraw 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 pump can handle 4, 6, 8, or 10 syringes, ranging from 0.5 µL to 10 mL.
Flow range 0.0033 nL/min-39 mL/min, accuracy ≤ ±0.35%.
