Smart Syringe Pumps: IoT Integration And AI-Based Flow Control

The syringe pump is an indispensable precision instrument in modern laboratories. It achieves high-precision liquid delivery by mechanically pushing the syringe piston. Compared with the traditional manual injection method, the syringe pump has significant advantages such as precise and controllable flow, good repeatability, and programmable operation. With the rapid development of cutting-edge fields such as nanotechnology and biotechnology, the precision requirements for micro-liquid delivery are getting higher and higher, and the syringe pump technology is also constantly improving. This article aims to comprehensively introduce the technical characteristics and application status of laboratory syringe pumps, and provide a reference for scientific researchers to choose appropriate syringe pump equipment.

2. Working principle and classification of syringe pumps

2.1 Basic working principle

The core working principle of the syringe pump is to drive the screw mechanism through a stepper motor or servo motor to accurately control the displacement of the syringe piston. The system calculates the speed at which the piston needs to move according to the set flow parameters, converts the rotary motion into linear motion through precise mechanical transmission, and pushes the liquid in the syringe to be output at a constant flow rate.

2.2 Main technical parameters

Flow range: Modern laboratory syringe pumps usually have a wide range of flow regulation capabilities from 0.001μL/min to 100mL/min

Flow accuracy: high-end products can reach ±0.5% or higher

Pressure range: generally up to 0-200psi (about 1.38MPa)

Resolution: displacement resolution can reach below 0.1μm
