(Including Degassing Pressure Display Accuracy ›0.01 MPa
and Injection Valve) Injection Valve Pressure Resistance 35 MPa
Injection Valve Material PEEK
Injection Valve Orifice 0.4 mm
Degassing Each chromatographic pump module is equipped with a standard
degassing system to quickly remove micro-bubbles in the mobile
phase and ensure system stability.
Modular pump-valve Plus a large-capacity Gradient Elution The main unit can accommodate 2 sets of independent
chromatographic pump modules simultaneously to achieve
degassing modules high-precision column oven binary high-pressure gradient functionality.
Type Adopts forced air heating circulation technology to ensure
temperature stability.
