What Is a Syringe Pump?
A syringe pump is made up of a precision linear drive for aspirating and dispensing discrete volumes of fluid or gas by actuating a syringe. In most cases, there is also a rotary valve driver that can actuate a valve to direct flow through specific ports for aspirate and dispense. The syringe pump is often integrated into a larger clinical or analytical instrument, as a critical component for metering and directing fluid.
Pros & Cons of Syringe Pumps
Advantages of Syringe Pumps
Syringe pumps are great for aspirating and dispensing discrete volumes of fluid. Because there are multiple syringe volumes and pump resolutions, there is a wide range of dispense volumes and dispense speeds available. This combination of precision syringes and syringe pumps provide very accurate and repeatable dispense volumes.
Disadvantages of Syringe Pumps
Syringe pumps are not good for continuous flow applications. Because a syringe has a maximum volume, it will have to refill to dispense any volumes greater than its maximum volume. Syringe pumps are typically large to accommodate a fully aspirated syringe plus the motors that drive the syringe and valve.
