Syringe Pump

A Syringe Pump, (also called Infusion Pump, Media Dispenser, or Culture Media Dispenser) is a tiny positive displacement pump used in chemical and biological research for the purpose of progressively administering exact volumes of fluid.

The pace and duration of the fluid are controlled using internal software in a motor-driven device. A step motor is utilized to propel the plunger, which then pushes fluids through the needle. A syringe pump machine may be used for medical or research goals, depending on the user’s requirements. They are also capable of withdrawing fluids and utilizing numerous syringes simultaneously.

What Is a Laboratory Syringe Pump?

Researchers use a laboratory syringe pump in their research for the following top three reasons:

  • Precision

  • Accuracy

  • No pulsation

Syringe pump systems outperform medical syringe pumps by numerous orders of magnitude in terms of precision and accuracy. Syringe infusion pumps also guarantee a constant flow since, unlike peristaltic or piston pumps, they don’t pulse.

Scientific and research syringe pumps, also known as laboratory syringe pumps, can often inject smaller amounts of liquid with higher accuracy than medical syringe pumps. They can often be programmed with more sophisticated routines as well. Laboratory syringe pumps are made to be flexible and adaptable, in contrast to medical syringe pumps, which are made for highly particular, specified purposes. A syringe pump may be used in a wide variety of research settings, including thin film production, mass spectrometry, flow chemistry, microfluidics, and other areas.

Syringe Pumps’ Operational Features

  • Syringe Clamps: keep syringes in place during function.

  • Pusher Block: contacts the plunger, initiating flow.

  • Interface: allows you to easily control flow rates and volumes through programming that lets you look up syringe sizes and schedule delay times.


Syringe pumps can be categorized into four groups regarding their operating pressure:

  • Low Pressure (290N): This syringe pump suitable for high precise dosage of small volumes (nanolitres).

  • Mid Pressure (1000N): This syringe pumps are made for the precise injection of fluids into systems under higher pressures (200 bar).

  • High Pressure (2600N): This work the same as mid pressure bar, but dosing technology pressure can be ranges up to 510 bar.

  • Ultra High Pressure (7000N): This Ultra high pressure is suitable for extreme conditions in terms of high pressures (up to 13,000 psi).

What are the Advantages of Using a Syringe Pump?

The following are some of the benefits of utilizing a syringe pump:

  • They aid in maintaining a consistent flow of fluids without any vibration.

  • High-precision syringe pumps are able to inject even the lowest volumetric flows down to pico-liters.

  • Syringe pumps may be programmed for more precision, fewer mistakes, and the tracking of infusion history using a computer.

  • Higher viscosity fluids may be delivered using them.

Single vs. Dual Syringe Pumps

As the name implies, single syringe pumps can only control one syringe, whereas dual syringe pumps may, depending on the mode of operation, control either one or two syringes. Each pump, whether on a single or dual pump type, can be used to inject or remove a liquid continuously or to generate a pulsed flow.

There is a greater variety of experimental setups that may be employed when two syringes are controlled. As seen below, using two syringes, for instance, enables the exact blending of two distinct solutions. This method might potentially be utilized to create emulsions of two immiscible liquids. It can allow precise control of chemical reactions in systems like microfluidics.

Dual syringe pumps can be used to continuously pump a single solution when used in conjunction with tools like check valves and solvent reservoirs. Syringe pumps also provide separate control of each pump. So, if the experiment calls for it, one pump may be programmed to infuse while the other is in withdrawal mode, and it can be utilized as a single syringe pump if necessary.
