CL3030 High-performance Capillary Electrophoresis Liquid Chromatography with CL101B Intelligent High Voltage Power Supply (Negative Power Supply)

Feature

• ·    Imported motor, imported drive, imported efficient pulsation damper, strong buffer capacity, small pulsation, single-plunger reciprocating pump, proportional valve controlled with coded disc, high precision
• ·    Unique one-way valve design, no degassing required for mobile phase, imported sealing system, high pressure resistance. The anti-pressure device patent design makes bubbles not easy to enter the flow cell
• ·    The flow cell can be replaced, which makes it suitable for analytical high-performance liquid chromatography and high-performance capillary electrophoresis separation system
• ·    Safety control: upper and lower limit control of pressure, buzzer alarm, automatic shutdown
