The four-channel syringe pump (WH-SP-04) is a high-precision fluid control equipment independently developed by Wenhao Co., Ltd. The system has the characteristics of precision, stability, and strong anti-interference ability, and can be widely used in related fields such as microfluidic drive control.
The device is a syringe pump that combines liquid injection and liquid absorption. It is easy to use and easy to operate. The parameter setting, modification and view of fluid control can be completed in the main interface of starting up. The syringe can be directly selected from the list during parameter input You can also manually enter the model and inner diameter, and then enter other parameters (flow rate, flow rate, time, infusion type, etc.). The task can be paused at any time during the work process, and various parameters can be reset and executed immediately.

1.2.1 Determination of Syringe Model
(1) Search from the list
There is a list of standard syringes in the manufacturer’s brand. After the syringe model is selected, the program automatically loads the corresponding inner diameter value.
(2) Custom input
If there is no syringe used by the user in the syringe program list, you can directly enter the type and inner diameter of the syringe. The device can store multiple sets of user-defined syringe diameter values.
1.2.2 Target parameter input
Target parameters include: liquid volume, flow rate, and time. Choose to input any two parameters, and the other parameter system will get directly.
1.2.3 Power-down memory
When the device is running, the power supply is interrupted. After the power is restored, you can choose whether to continue working according to the previous parameters.
1.2.4 Traffic jam alarm
During the operation of the equipment, if the propulsion mechanism of the syringe pump is blocked, the syringe pump will stop the propulsion mechanism and sound a whistle alarm.
By calibrating the flow rate, a more accurate dispensing volume can be obtained.
