Principle and application of syringe pump

The principle of the syringe pump: the syringe pump injects and extracts the liquid through the movement of the piston (first inject and then withdraw, first withdraw and then inject continuous circulation);

The important components of the syringe pump are Syringe: It is one of the main components of the syringe pump. Before choosing, you must know the amount of liquid you need to inject, how many milliliters of the syringe pump, and then determine the specifications of the syringe.

Driver: Determined according to the liquid that needs to be transported and the function mode that needs to be used. For example, the distribution model of the liquid, under what environment it is used, multi-channel injection or single-channel injection, whether there is a requirement for liquid flow rate, and what is the accuracy of each injection.

The advantages and disadvantages of the syringe pump are as follows: The advantages of the syringe pump: The injection precision of the injection pump is one order of magnitude higher than that of the peristaltic pump. It can realize the function of automatically preparing the standard curve and improving work efficiency. Disadvantages: The syringe wears quickly and has a short service life. In addition, if the syringe inhales air, it will remain in the tube, which is difficult to eliminate, and the injection volume will be inaccurate.

Classification of syringe pumps: According to the purpose: it can be divided into microsyringe pumps for laboratory use and industrial syringe pumps.

Divided by the number of channels: single-channel and multi-channel

Application fields of syringe pumps: Syringe pumps have a wide range of applications, and most of them can be used in areas that need to transmit small flow liquids. Such as microfluidics, electrospinning, mass spectrometry, industrial transportation, and other fields.
