What is a syringe pump used for in a lab or a factory? It moves a small amount of liquid at a set speed. A plunger pushes the liquid out of a syringe. DK Infusetek lists these uses on its site: microfluidics, flow chemistry, battery work, coating, electrospinning and dispensing. Its pumps are for labs and factories. They are not for medical use.
These pumps do seven main jobs: microfluidics, electrospinning, lipid nanoparticle synthesis, flow chemistry, reagent dosing, precision coating and cell injection.
What Is a Syringe Pump Used For in Practice?
A syringe pump moves a small amount of liquid at a steady speed. Labs and factories use it when a tiny mistake can ruin the result. It helps with research, making fibers, adding chemicals and thin coating.

Real examples are on the Application page. They come in four groups: Life Science, Microfluidic, University Laboratory and Electrospinning.
How a Syringe Pump Delivers Controlled Flow
Flow rate equals linear speed times the inner cross-sectional area of the syringe. Linear speed is how fast the plunger moves. A wide syringe moves more liquid at the same speed. A narrow syringe gives a slower, finer flow.
The ISPLab01-Pro page gives two examples. A 1 mL plastic syringe has an inner diameter of 4.70 mm. Its flow is 0.0173 μL/min to 2.2889 mL/min. A 150 mL plastic syringe has an inner diameter of 40.00 mm. Its flow is 1.2566 μL/min to 165.8712 mL/min.
A motor and a lead screw push the plunger. This parts breakdown shows four main parts. They are the drive mechanism, the syringe holder and clamp, the plunger driver and the control interface.

Syringe Pump Uses in Microfluidics Research
Microfluidic work uses tiny amounts of liquid in very small channels. A syringe pump sends steady flow into those channels. The flow range of the ISPLab01-Pro is 0.008 nL/min to 165.871 mL/min.
Example From Heidelberg University
Heidelberg University started a new institute in 2022. It is called IMSEAM, short for the Institute for Molecular Systems Engineering and Advanced Materials. Its microfluidic station uses the ISPLab01. The Selhuber-Unkel Group used the pump to move deionized water, polystyrene beads and cell solution. The group was changing microfluidic chips with thermoresponsive hydrogels.
Electrospinning and Nanofiber Production
Electrospinning uses a high-voltage electric field. The field pulls a polymer solution into very thin fibers. The fibers are collected as nanofiber membranes or yarns.
The flow rate of the polymer solution sets how thick the fibers are. It also changes their shape, structure and strength.
What the ISPLab Series Offers
Flow range of 0.008 nL/min to 165.8 mL/min per channel
You can change the flow in real time without stopping the pump
Four modes: Infusion, Withdrawal, Infuse then Withdraw, and Withdraw then Infuse
RS232 and RS485 (MODBUS) ports connect it to computers and PLCs
Lipid Nanoparticle Synthesis in Biopharma
Lipid nanoparticles (LNPs) are tiny bubbles made of lipid. They protect bioactive molecules. In LNP experiments, the rate, volume and time of liquid delivery all matter.
The SPM modular pump works well for LNP preparation. Its linear speed is 1 μm/min to 132 mm/min. It can run up to eight independent modules at once. One screen shows all of them.
The pump calibrates itself automatically before infusion. You can change the flow in real time. It supports RS232/RS485 (MODBUS). It has power-loss memory and stores up to 10 modes. Each channel has its own occlusion alarm, which warns of a blockage.

Flow Chemistry and Precise Reagent Dosing
In flow chemistry, liquids move as a steady stream. A standard syringe pump must stop when the syringe is empty. A continuous flow model does not have that stop.

The SP60-8A has 8 channels and a rotary valve. It can do automated pipetting, dilution and dispensing. Its repeatability error is below 0.2%. Its accuracy error is below 1.0%. Both were measured at full stroke with deionized water.
The dispenser instructions from ClaremontBio recommend the DK INFUSETEK SPLab/ISPLab series. They are for the Automated Lateral Flow Reagent Dispenser.
Precision Coating in Industrial Production
Precision coating puts a thin, even layer of liquid on a surface. The SP60-1A page names five industries. They are automotive glass, electronic coatings, optical lens thin-film deposition, battery electrode fabrication and printing ink. Uneven flow can leave streaks and uneven thickness.
The SP60-1A speed range is 0.01 mm/s to 60 mm/s. Its speed resolution is 0.01 mm/s. Its volumetric accuracy is below 1%. That is at full stroke with deionized water. An optical encoder spots missed steps. RS232, RS485 and CAN links let it run up to 15 coating heads or spray nozzles. It also has 2 TTL inputs and 3 TTL outputs. They sync it with other devices.
Cell Injection and 3D Cell Printing Support
3D cell printing constructs tissue-like structures layer by layer. Bioink is filled with live cells and extruded via a precise nozzle. Changes in flow or pressure spikes might damage the cells.
DK Infusetek used its SPM/3×ZU-I pump in a 3D cell printing machine. Speed range of SPM is 1 µm/min to 132 mm/min. Accuracy of placement ≤±0.5%. Each channel is independent. It also offers real time monitoring and retract distance settings.
For cell injection and other suspension work, DK Infusetek has the MIX60 stirring pump. It also provides a stirrer for the pump. It has a 10 ml glass syringe with a stirrer within it. It can manage up to 20 functioning stages. One common usage for suspensions is to inject cells.
Syringe Pump vs Infusion Pump: Key Difference
A plunger is pushed by a syringe pump. Best for tiny amounts and extremely slow, fine flow. An infusion pump pushes a fluid via tubes from a bag. It is suitable for huge quantities and extended delivery.
Not better each time. Each one. The proper decision relies on volume, flow rate, and run time. The comparison article has more detail.
How to Read Syringe Pump Accuracy Numbers
Each accuracy value is related to one model and one test scenario. Don’t compare numbers between models until you’ve verified the test configuration.
The ISPLab01-Pro has an error of less than or equal to plus or minus 0.3% for stroke >= 30 % of the maximum stroke. Under a similar rule, the CFSP-I/CU-I error is ≤±0.1%. Shorter strokes are not included in these figures.

Check four things before you choose. They are flow range, syringe size, number of channels and how you control it (touch screen, RS232 or RS485). The site sorts its pumps into four groups: laboratory, continuous flow, modular and industrial pumps.

FAQs
What is a syringe pump used for?
A syringe pump is used to move small amounts of liquid at a set speed. DK Infusetek lists six fields, including battery work and coating. Its pumps are for labs and factories.
How does a syringe pump control flow rate?
A syringe pump sets flow rate with plunger speed and syringe size. Flow rate equals linear speed times the syringe's inner cross-sectional area. A motor and lead screw move the plunger at the set speed.
Is a syringe pump the same as an infusion pump?
No. A syringe pump pushes a plunger. It works best for small volumes and very slow, fine flow. An infusion pump moves fluid from a bag through tubing. It works best for large volumes and long delivery.

The ISPLab Series works well for electrospinning, says DK Infusetek. Its flow range is 0.008 nL/min to 165.8 mL/min per channel. You can change the flow in real time without stopping the pump.
Can a syringe pump run continuous flow?
Yes, a continuous flow model can. The CFSP-I/CU-I has a continuous flow range of 0.06 μL/min to 70 mL/min. A standard syringe pump must stop when the syringe is empty.
What are the main parts of a syringe pump?
A syringe pump has four main parts. They are the drive mechanism (motor and lead screw), the syringe holder and clamp, the plunger driver and the control interface, where you set the flow.
Conclusion
