WH-SP-08 Syringe Pump System

Introduction

The eight-channel syringe pump (WH-SP-08) 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 can be installed with up to 10 syringes. It is easy to use and simple to operate. It can complete the parameter setting, modification and view of fluid control in the main interface of the startup. The parameter input process The model and inner diameter of the syringe can be selected directly from the list, or manually input, and then other parameters (flow rate, flow rate, time, infusion type, etc.) can be input. The task can be paused at any time during the work process, and various settings can be reset Parameters and execute immediately.

Features

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 inner 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.

1.2.5 Calibration

        By calibrating the flow rate, a more accurate dispensing volume can be obtained.

1.3 Graphical interface features

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

        ØSetting and real-time display of operating parameters;

        ØSetting and monitoring of operating range;

        ØReal-time monitoring of operation progress.
