CX-HL series high-pressure infusion pump is a high-precision, low-pulsation high-pressure infusion pump, which can achieve large flow and stable solvent delivery. The flow rate of liquid delivery can range from 0.001mL/min to 3000mL/min.
As an infusion system, in the process of sample purification, it can be used as a solvent delivery pump to provide stable mobile phase delivery for the purification process. In addition, it can also be used as an injection pump for the injection of large-volume samples during the preparation process to provide accurate injection volume.

Its main features are as follows:

• Double plunger series mode, floating plunger design;
• Advanced pump drive system makes the pump performance better, higher precision, and better stability;
• Adopt electronic pulsation compensation technology, multi-point flow correction, to ensure flow accuracy in the full flow range, more accurate flow rate, more stable performance, reliable operation, and high cost performance
• Open computer anti-control communication protocol, convenient for third-party software control;
• Touch screen design;
• Humanized interface design;
• Flow multi-point calibration;
• The firmware program can be updated online;
• Power-off protection;
• LAN connection, stable data transmission;
• The instrument can alarm in time and automatically stop the operation of the pump according to the set procedure.

√The power supply is a 90V~240V wide voltage input switching power supply, which supplies power to the cooling system, stepper motor driver, control system and other devices.
√The control system is the core part of the CX-HL series of high-pressure infusion pumps. It allows users to set the flow rate according to their needs, select the working mode of the pump, write time programs and GLP event records, etc.
√The pressure measurement system can measure the size of the liquid pressure in the liquid path, and the user can select different chromatographic columns and mobile phases according to this value; by setting the maximum pressure and minimum pressure, the high-pressure infusion pump can be in the best working state and avoid Occurrence of overpressure and leakage.
√The stepper motor driver and stepper motor are high-voltage power devices, which ensure that the liquid in the liquid path can smoothly flow through the chromatographic column and the flow cell, so that the infusion work can proceed smoothly.
√The pump housing unit part mainly includes pump head assembly, one-way valve assembly, cam mechanism and so on.
According to different infusion volume, CX-HL series infusion pump can be divided into the following seven types:
