Syringe Pumps vs Peristaltic Pumps


Different applications require a pump, among all the options peristaltic and syringe pump systems, are the most suitable. However, the selection of the best is always a disjunctive. In general terms, laboratory and industrial processes use peristaltic pumps. A user needs to know more about the systems and proper comparison of these technologies. In some cases is difficult to understand what are the fundamental differences between the pumps that a scientist can find in the laboratory. In this review, we address the main characteristics, pros, and cons of peristaltic and syringe pumps.

What Is A Peristaltic Pump?

Peristaltic liquid pumps squeeze plastic tubing through rollers in rotatory movement. Perhaps, are the most affordable option and reliable, especially for large rates and volumes. One significant advantage is that the peristaltic pump system never touches the sample. However, the tubing has to be replaced from time to time. Laboratory peristaltic pumps are not the most reliable option for slow rates and small volumes due to the pauses in the flow; this is a disadvantage that generates pulses which may affect the operation of high-precision applications. The study of microfluidics, for example, is not recommended through high-volume peristaltic pumps.

What Is A Syringe Pump?

Syringe pumps are classical syringe holders, with a motor-controlled plate and stepper motors that allow tow work at minimal rates as one microliter/min. Chemyx offers the Fusion 200 two-channel syringe pump, which allows a broad pallet of rates for different applications, especially microfluidics and nanoliter control. Furthermore, in some cases, picoliter control is achieved with this pump. The handling of damaging liquids such as inks or corrosives is possible due to the new syringe bodies. Additionally, this allows the application of high-viscosity liquids and high pressure.


Even though peristaltic pumps are inexpensive devices compared to syringe pumps, the applications for both pumps are entirely different, higher flow control is provided by syringe pumps and the applications that require this exceptional tune flow are mainly: fluid batteries, microfluidic reactors, micro and nanomanufacturing among others. Furthermore, classical HPLC and GC/MS equipment can implement syringe pumps; on the contrary, peristaltic pumps are more reliable for high-volume applications. Syringe pumps are the most reliable option for Biological and biochemical studies, biotechnological areas require complex operations as gradients for drugs and therapeutic interventions.

Concluding Remarks

Chemyx offers syringe pump systems to its valuable clients due to its facility to provide the most reliable and controllable flux, in the case of peristaltic pumps are suitable equipment for rough studies which no require an excellent tune control in a small volume. Such applications cannot be reached by the peristaltic pumps, for that reason if a user is looking for the applications above mentioned the Chemyx syringe pumps are the best choice over simple peristaltic pumps.
