Four channel continuous injection perfusion system WH-CPS-04

1 Introduction

Product categories: cyclic injection pump cell perfusion system, vertical syringe pump, micro-injection pump, micro-syringe pump.
The cyclic injection pump/cell perfusion system can simulate cell culture under physiological conditions and is usually operated on a biochip or cell flow chamber.
The continuous injection perfusion system (vertical continuous micro-injection pump) is a perfusion/extraction type microfluidic sampling device, including three standard products:
One group: WH-CPS-02 continuous injection perfusion system (equipped with two syringes);
The second group: WH-CPS-04 continuous injection perfusion system (equipped with four syringes);
Three groups: WH-CPS-06 continuous injection perfusion system (equipped with six syringes).
Wenhao shares provide more channel customization services, such as 8, 10, 12, and other microfluidic sampling equipment!
The continuous injection perfusion system (WH-CPS-04) is a high-precision fluid control equipment independently developed by Wenhao Co., Ltd. This 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 contains four sets of propulsion modules. The switching valve of each set only needs to be connected with a simple pipeline to achieve two continuous channels for uninterrupted liquid injection, and each set of propulsion modules can inject or draw liquid at different speeds. It is easy to use and simple to operate. The parameter setting, modification, and view of fluid control can be completed in the main interface of starting up. During the parameter input process, the model and inner diameter of the syringe can be selected directly from the list or manually input, and then input other parameters ( Flow rate, flow rate, time, infusion type, etc.). The task can be paused at any time during the work, and various parameters can be reset and executed immediately.

3. Features

3.1 Channel settings
Each channel can be set separately and can also be operated in a unified manner such as “fast forward,” “fast rewind,” “start,” “pause,” and so on.
3.2 Determination of Syringe Type
Each channel can be placed with different brands and specifications of syringes (the head 1/4-28UNF outer teeth, the tail M3 inner teeth).
(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 inner diameter values.
3.3 Target parameter input
Target parameters include liquid volume, flow rate, and time. Choose to input any two parameters, and the other parameter will be obtained directly by the system.

4. Graphical interface features

For the display of the syringe specification library, you can select the corresponding type according to your needs;
The current operating mode and status of each channel, and the delay between each channel;
Real-time individual control of each channel and unified control of all channels.
