Programmable Syringe Pump is a device that can precisely control liquid flow and is commonly used in fields such as chemistry, medicine, pharmaceuticals, and biotechnology. It pushes or extracts liquid in the syringe through a motor-driven piston, achieving high-precision and high repeatability liquid injection.
principle
Basic structure:
Syringe: As a container for storing and transporting liquids, it usually has different capacities (such as 1mL, 5mL, 10mL, etc.).
Motor: responsible for driving the piston of the syringe, usually a stepper motor, to achieve high-precision and controllable movement.
Control system: including microcontrollers or computers, used for programming injection rate, volume, and other parameters.
Working Principle:
Syringe filling: Fill the liquid to be tested into the syringe and correctly install it onto the pump fixture.
Program settings: Set the required injection program through the control panel or computer software, including parameters such as flow rate (e.g. µ L/min), injection volume, and time.
Liquid delivery: After starting the pump, the motor drives the piston to move forward or backward, pushing the liquid from the syringe to be delivered to the target container or equipment, or extracting the liquid from the target container.
Feedback control: Some programmable injection pumps are equipped with sensors that can monitor liquid flow in real-time and automatically adjust flow rate and volume based on feedback information to ensure the accuracy of injection.
application
Programmable injection pumps have a wide range of applications, and the following are some of the main application areas:
