Product introduction

LSP02-2B Laboratory injection pump is a perfusion/extraction type dual-channel injection pump, mainly used in the laboratory, with a full-size structure, excellent electromagnetic compatibility performance, ESD≥IV (IEC 61000-4-2). Multiple modes of operation enable it to adapt to the needs of a wide variety of applications in different fields. It has a very high control accuracy and a wide range of linear velocity, is the ideal high precision, small flow, low pulsation liquid transmission equipment; LSP02-2B injection pump is widely used in chemical reaction injection experiments, electrostatic spinning, long-term animal drug injection experiments and other laboratory microinjection experiments.

Functional characteristics

LSP02-2B Syringe inner diameter input function: You can select the syringe from the list or directly enter the syringe inner diameter

Man-machine interface friendly: large screen LCD display, digital knob in the film key to cooperate with the use, easy to operate, fast

Five working modes: perfusion/extraction/first perfusion and then extraction/first extraction and then perfusion/continuous operation

Power failure memory function: 1.EEPROM saves setting parameters. After powering on the PROM again, you do not need to reset parameters. 2. The system is powered off when running in flow mode. After the system is powered on again, the system can continue to run or stop according to the set parameters

Traffic jam protection function: When the propulsion mechanism of the injection pump is blocked during the working process, the injection pump will stop the work of the propulsion mechanism and give a siren alarm

485 communication bus can be connected with the host computer, through the background software to control it.

External control interface: provides input/output control functions

Liquid level calibration function: More accurate flow rate can be obtained through the calibration procedure

Syringe protection function: By adjusting the position of the limit block, the syringe can be prevented from being damaged
