Product Manual

LSP02-3BH Independent Control High-Pressure Injection Pump

Product Description

Commodity name: LSP02-3BH Independent Control High-Pressure Injection Pump

Product Introduction

◆ The LSP02-3BH is a high-pressure, dual-channel, independently controlled infusion/withdrawal microliter syringe pump, suitable for high-precision transfer of high-viscosity, high-pressure liquids.

◆ Maximum thrust 600N

◆ Flow rate range: 0.764nl/min-197.669ml/min.

◆ Capable of accommodating different specifications of stainless steel syringes, injectors, or other syringes

◆ User-friendly human-machine interface: Large screen LCD display, digital rotary knob and membrane keypad for easy and quick operation.

◆ 5 working modes: Infusion mode, Withdrawal mode, Withdrawal-infusion mode, Infusion-withdrawal mode, Continuous mode.

◆ Power-off memory function: 1. EEPROM saves setting parameters, no need to reset after power-on.

◆ Using 485 communication bus, it can be connected to the host computer and controlled through the background software.

◆ External control interface: With input/output control functions.

◆ Liquid volume calibration function: More accurate flow rate can be obtained through the calibration program.

Typical Applications

◆ Biological laboratory

◆ High-pressure, high-viscosity liquid transfer
