High precision 10-channel micro laboratory syringe pump

The high precision 10-channel micro laboratory syringe pump is engineered to deliver versatile and accurate performance, catering to a wide range of laboratory applications. Users benefit from the convenience of inputting syringe inner diameters from a list or directly through membrane buttons, facilitated by a user-friendly human-machine interface featuring a large LCD display and a digital knob for quick and straightforward operation. Offering four distinct working modes—perfusion, extraction, extraction perfusion, and continuous—the syringe pump adapts seamlessly to diverse applications. Its memory function, stored in an EEPROM, eliminates the need for manual resetting after power-on, ensuring operational continuity. In flow mode, the pump seamlessly resumes operations based on the pre-configured parameters if power is interrupted, enhancing efficiency.

Safety is a priority with the incorporation of a protection function that halts the pump's propulsion mechanism and generates an audible alarm when encountering an obstruction, preventing potential damage. Advanced control options are facilitated by the syringe pump's connectivity to a host computer via a 485 communication bus, allowing seamless control through background software. The external control interface enhances flexibility with input/output control capabilities. Calibration functionality ensures precise flow rates, and a syringe protection function adjusts the limit block position to safeguard against potential damage.

The syringe pump's technical parameters are impressive, operating in perfusion mode with a remarkable flow range from 0.831 μL/min to 21.675 mL/min, making it adaptable for diverse needs. Capable of accommodating ten syringes, it offers substantial flexibility in laboratory settings. With a maximum stroke of 140mm and a stroke resolution of 0.156μm, the pump ensures precise fluid dispensing. Its line speed range spans from 5 μm/min to 130 mm/min, with reliable stroke control accuracy of ≤0.5% when exceeding 30% of the maximum stroke. The pump exhibits robust performance with a rated linear thrust of over 180N, providing dependable operation. Syringe selection is user-friendly, allowing direct input of the inner diameter or selection from built-in options of the main manufacturer's syringe models.

Precision is further enhanced with flow correction via a calibration procedure, enabling fine-tuning of parameters such as dispensing liquid volume and injection time. The flexibility extends to parameter display options, allowing users to choose between fluid volume, flow rate, or linear velocity. The syringe pump incorporates a power-down memory function, resuming operation based on the pre-power-off state upon restart, ensuring continuous workflow. For effective control and status indication, the pump offers a 2-channel OC gate signal output and multiple control signal inputs, including channels for start/stop control and TTL level signal control.

Seamless connectivity is achieved through the RS485 communication interface, enhancing control capabilities. The syringe pump's dimensions of 280×210×140 mm and a weight of 4.5 kg contribute to its compact design. Operating within a power supply range of AC 200V-260V with a power consumption of 35W, it thrives in a laboratory environment with a relative humidity of less than 80% and a temperature range of 0°C to 40°C, ensuring reliable and accurate performance.
