What is a Syringe pump?

A syringe pump is a type of infusion pump used to gradually deliver a small amount of fluid (with or without drugs) to a patient or for chemical and medical research. Some syringe controllers can inject and remove solutions.

Type of Syringe Pump

The syringe pump has the following two types:

  1. laboratory syringe pumps 
  2. medical injection pumps

1) Laboratory syringe pumps 

In research laboratories for applications that require very precise liquid delivery, this equipment is used. The laboratory pumps generally control less volume and offer additional functionality that medical pumps do not have. Installed modular syringe pump and high-pressure syringe pump. Recently, OEM modular syringe pumps and high-pressure syringe pumps have become useful in industrial applications.

2) Medical Injection Pumps

This syringe pump uses to deliver controlled amounts of fluids (such as nutrition, medicine, and blood) to patients. This injection pump can be used for in vivo diagnosis, treatment, and research.

Purpose and performance of Syringe Pump

In research laboratories, syringe pumps can be used for almost any application that requires accurate measurements, especially at the micron and nanometer levels. They are used as precision dosing systems in many research fields or to accurately handle small quantities of reagents, mix very small quantities and add specific chemicals during testing. Additionally, syringe pumps on the market are compatible with microfluidic applications and facilitate research in areas such as microenvironment control. 

The microfluidic applications of the syringe pump have been greatly improved in the field of vaccine research. The syringe pump can also facilitate accurate injection in medical and biological research. For example, in neuroscience research, feeding small animals or administering very small doses to specific parts of the brain.

In industrial applications, syringe pumps can amplify, develop new materials, and have chemical, pharmaceutical, catalytic, and materials research properties. They can also play an important role in minimizing errors in instrumental microanalysis and analysis such as mass spectrometry (MS), high-performance liquid chromatography (HPLC), and liquid chromatography-mass spectrometry (LC-MS).

Construction of Syringe Pump

The syringe pump design has 3 main components, including:

  1. Hardware (machined bracket and lead screw)
  2. Motor (and electronic actuators)
  3. Software (UI and I / O)

1) Hardware

Different size syringes are held in place by the adjustable syringe clip (a). Move the screw (b) and guide rod (c) to the pressure block (d) to start the injection. Learn more about the syringe pump components and hardware. Injection pump components and injection pump components are usually lubricated with carbon or lithium grease. Learn more about lubrication conditions.

2) Electronics

All positive displacement syringe pumps are driven by a stepper motor connected to a lead screw, which controls angular motion. Further development of microelectronics technology will enable RS232 wired control and USB wired control.

Modern syringe pump designs generally include an LCD touch screen controller as the primary input and output device.

Auxiliary input and output control can use RS232 or USB control. Learn more about connecting syringe pumps to your computer.

Advantages and disadvantages of the syringe pump.

A syringe pump uses to control the minimum fluid flow rate in a planned, adjustable, and effective way. Syringe pumps are widely used in medicine for continuous injection of drugs. However, in the past few decades, syringe pumps have expanded their reach and entered the field of research.

Technology is moving towards automation and scaling, hence the introduction of the “smart bomb,” which brings research excellence and greater accuracy, greater accuracy and advanced digital data storage, access to dose guidance, and additional benefits. 

Advantages of Syringe Pump

  1. The syringe pump can control the pressure for easy handling of high-pressure liquids.
  2. A syringe pump equipped with a heater provides temperature control.
  3. Some syringe pumps allow you to switch between syringes for maximum access.
  4. Most modern syringe pumps can be programmed for greater accuracy and better control. Some models can be connected to a computer to control the computer and record injection or extraction history.
  5. The syringe pump is quick and easy to use.
  6. The syringe pump allows the user to determine the total volume of liquid and accurately dispense it.
  7. The high-pressure syringe pump can adjust the target pressure or control to perform a constant pressure test.

Disadvantages of the Syringe Pump

  1. The amount of syringe used limits the amount of fluid dispensed
  2. Excessive resistance can cause pressure and possibly damage the syringe pump.
  3. Without a current sensor, there is no way to know the current in a temporary state. 


When choosing a syringe pump for test setup, it is important to consider the following key factors.

When choosing a syringe pump for test setup, it is important to consider the following key factors.

As we all know, the syringe pump offers stability and responsiveness. The slightest movement of the motor determines the flow stability of the syringe pump, and the response depends on the fluid mechanics, resistance, and compatibility of the test device. To use the syringe pump for the best response, the test parameters must be within the range of the syringe pump.

In other words, the syringe pump can help speed up research and reduce errors that can occur when administering fluids in many advanced research areas.
