322-H2 Pump (Compact Version)

The 322-H2 Pump is a high-performance binary solvent pump with quick gradient response and software control for analytical to semi-preparative HPLC applications.

Overview × The 322 HPLC Pump is a binary solvent pump for analytical to semi-preparative high performance liquid chromatography (HPLC). It accommodates flow rates from 0.15 mL/min up to 30 mL/min at pressures up to 8700 psi (600 bar). The 322 Pump front panel controls power and indicates pump status. Quick Gradient Response High-pressure Adjustable Volume Dynamic Mixer (AVDM™) enables fast gradient response times and homogeneous mixtures for analytical to semi-preparative applications. The adjustable mixing volume allows for easy methods switching from other HPLC system brands. The Right Pump for Your Task Two interchangeable pump head types are available to meet your application needs: • H1 pump heads: ideal for 2–12 mm ID columns with flows up to 15 mL/min and pressures up to 8,700 psi (600 bar) • H2 pump heads: ideal for 3–20 mm ID columns with flows up to 30 mL/min and pressures up to 4,300 psi (300 bar) The pump heads are easy to access and simple to maintain. Software Control The 322 Pump is controlled by an external software, such as TRILUTION® LC.
