Two-way continuous syringe pump product introduction
The bidirectional continuous syringe pump (WH-BCSP-22) is a high-precision microfluidic drive and control equipment independently developed by Wenhao Co., Ltd. It has the characteristics of precision, stability, and strong anti-interference ability. It can be widely used in microfluidic drive and control. field.
The laboratory syringe pump is a perfusion/extraction type dual-channel bidirectional push-pull syringe pump, which is widely used in biology, chemical reaction injection experiments, long-term animal drug injection experiments, electrospinning applications, microfluidics and other laboratory microinjections For experiments, the syringe is pushed through a mechanical device to achieve high-precision and smooth liquid transmission.
The bidirectional continuous syringe pump is a syringe pump that combines liquid injection, liquid aspiration, and continuous modes. It contains two independent fluid flow paths. Each set of flow paths can be connected to several external pipes to achieve continuous drive and transfer of liquid. The equipment is easy to use and simple to operate. The parameter setting, modification and view of the microfluidic drive control can be completed in the main interface of the boot. The model and inner diameter of the syringe can be directly selected from the list during the parameter input process, or manually input and then input Other parameters (flow rate, flow rate, time, infusion type, etc.) are sufficient, and 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 syringe model and inner diameter value, and multiple sets of user-defined syringe models and inner diameter values can be stored.
1.2.2 Target parameter input
Target parameters include: liquid volume, flow rate, and time. After selecting and inputting any two parameters, the system will automatically give another parameter.
1.2.3 Number of cycles
The set stroke in a single direction is a microfluid distribution (liquid suction or injection process). When the number of cycles is set to 1, the single run ends and the process is completed. When the number of cycles is set to 0, it is an infinite cycle, that is, after each set stroke, it changes direction and restarts operation until it stops manually.
1.2.4 Delay time
In multiple runs, a certain interval time can be set between the two runs.
1.2.5 Stroke adjustment
After selecting the syringe model, adjust the position of the syringe pump stroke adjustment block according to the stroke length of the syringe. If the stroke is too short, the syringe cannot be fully utilized (it is recommended to set 40%-80% syringe calibration stroke); if the stroke is too long, it may Cause the syringe plunger to fall out, causing liquid leakage.
1.2.6 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.
