Main application: biological laboratory
Product introduction
LSP04-1A Laboratory injection pump is a four-channel single-push mode injection pump, mainly used in biological laboratories, with an integrated structure. Can be loaded with different specifications of syringes (sampler), LSP04-1A laboratory injection pump is suitable for high-precision, small flow liquid transfer.
Functional characteristics
LSP04-1A Syringe diameter input function: You can select the syringe from the list or directly enter the syringe diameter to determine the syringe
Working mode: single push mode
Easy to operate: large screen LCD display, digital knob and film keys are intuitive and easy to operate
Communication function: The 485 communication bus can be connected with the host computer, and it can be controlled through the background
External control interface: with input/output control function
Power failure memory function: 1. The EEPROM saves the Settings. After the EEPROM is powered on again, you do not need to reset the Settings. 2. The system is powered off when it is running in traffic mode. After the system is powered on, the system can continue to run or stop according to the set parameters
Liquid 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
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 emit a siren alarm
