WH-CPS-02 Vertical dual-channel micro continuous perfusion syringe pump

1 Introduction

The continuous injection perfusion system (WH-CPS-02) 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 two-way propulsion modules, and the switching valve of each way only needs to be connected with a simple pipeline to realize continuous liquid injection. 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 parameter input, 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 individually set for parameter settings, and can also be used for operations such as “fast forward”, “fast rewind”, “start”, and “pause”.

3.2 Determination of Syringe Model

Each channel can place syringes of different brands and specifications (the head is 1/4-28UNF outer teeth, and the tail is φ4.5 hole).

(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 system will be directly obtained.

 

4. Graphical interface features

ØThe display of the syringe specification library, you can select the corresponding type according to your needs;

ØThe current operating mode and status of each channel, and the delay between each channel;

ØReal-time individual control of each channel and unified control of all channels.
