Syringe pumps (also known as syringe drivers) move fixed volumes of solutions at a specified rate. They do this by pushing on one or more syringes; single channel syringe pumps control one syringe, while dual channel syringe pumps control two in tandem. Scientific and laboratory syringe pumps are often capable of both infusing and withdrawing fluids at variable speeds to allow you to perform complex routines. Most such devices will let you program these routines into the devices so that you can easily repeat them across multiple experimental runs.

Laboratory syringe pumps are extremely versatile and are an essential piece of equipment for dispensing or extracting solutions in a controlled manner. They provide researchers with the ability to control the dispense rates of solutions with a degree of accuracy and precision that would be impossible to obtain by hand. As a result, syringe pumps are used in a range of experimental setups. Syringe pumps are also sometimes built into other pieces of equipment. The Ossila Slot-Die Coater, for example, uses a single syringe pump to supply a precisely control the rate of flow of the solution to the slot-die head. This helps ensure an even coating.

Our low price syringe pumps make no compromise in quality, using the same precision stepper motor that we use in our dip coater to provide an excellent degree of accuracy. Fully programmable, they enable effortless, automatic solution dispensing.

Two models of syringe pump are available: the Ossila Single Syringe Pump and the Ossila Dual Syringe Pump. In addition, if you are looking to use your syringe pump in your thin film fabrication process, our spin coater and syringe pump bundles offer excellent value. We also sell multiple syringe pump accessories, all of which are available to buy worldwide either online or via our customer support team.

Syringe Pump Buying Guide

---

There are a wide variety of syringe pumps available on the market. Understanding the key features is critical in making the right choice for your experiment.

Number of Channels

Each syringe that is part of a syringe pump is its own channel. Syringe pumps allow you to attach and use one or many syringes (or channels) at a time. Single channel pumps are useful for simple experiments where you only need to work with a single fluid. If your experiment requires the control of multiple fluids or continual pumping, look for a pump with multiple channels such as the Ossila Dual Syringe Pump.

Syringe Compatibility

A syringe pump is only as good as the syringes that you can use with it. It is important therefore to ensure that the pump you are using has as wider compatibility with different syringes as possible. The compatibility of syringes will be dependent upon the clamping mechanism and the design of the barrel and plunger flanges of the syringes. You should always contact the pump manufacturer to ensure that your syringes are compatible with a system. Our syringe pumps are compatible with many of the leading brands of syringe, but we recommend using Norm-Ject disposable Luer Lock syringes.

Channel Independence

Do you need to control each syringe independent of one another? Many syringe pumps only have a single motor to move all the syringes. This means that when one syringe dispenses, all syringes dispense. This lack of independence in control often limits what you can do with the system. Dependent multi-channel pumps have their uses when running the same dispense rates for different types of solution. However, if you are looking to use multiple syringes with different pump rates, channel independence (a feature of our dual pump model) is critical.

Withdrawal and Infusion

Most people primarily use syringe pumps in infusion mode. In infusion mode, the syringe pump pushes liquid out of the syringe. However, some syringe pumps can offer the functionality of withdrawing solution by reversing the motion of the pump. Our systems can clamp the syringe plunger, so that when the motor moves backwards, it drags the plunger backwards too. All syringe pumps with a withdrawal mode will have a similar mechanism. If you need to remove solution or are looking for continual pumping, this is essential feature.

Dispense Range

The dispense range of a syringe pump is determined both by the syringe you are using and the rate at which the motor can depress the plunger. Are you happy to switch to different size syringes to adjust the flow rate, or do you need to have complete control? If you need uninterrupted dispensing, look for a pump with a wide range of motor motion.

Dispense Accuracy

The accuracy with which a syringe pump dispenses the solution is important when you want to ensure that the amount dispensed stays the same across multiple different experiments. The accuracy of the pump itself is determined by the microcontroller circuitry and is often extremely accurate. However, the errors associated with the pump are often far outweighed by the errors in syringe diameter. The quoted accuracy of syringe pumps can therefore be misleading due to not accounting for errors associated with the syringes.

Pump Force

No motor can product infinite force. In the context of a syringe pump, this means that there is a maximum lateral force that the motor will be able to exert on the syringe plunger. Larger motors tend to be able to produce a higher force. This will allow you to move high viscosity liquids or use smaller diameter pipes. However, you should take care to ensure that the maximum pressure in the syringe does not exceed its tolerance. Some pumps, including both our single syringe pump and dual syringe pump, will offer force control so that you can set a maximum allowed force. This is particularly useful when you need to protect delicate syringes such as those made from glass or plastic.
