TS-2A/L0107-2A is a four channel push-pull mode microinjection pump mainly used in biological laboratories. The controller and execution unit are separate structures, and the execution unit has a clamping mechanism. The TS-2A/L0107-2A constant flow pump can be installed with a standard injector of μ L specification, with precise stroke control and a wide range of line speeds (7.9 μ m/min -79.4mm/min) to meet the needs of different users. The vertical installation structure can be conveniently used in conjunction with biological instruments such as micro manipulators and stereotaxic brain locators, and is widely used in various fields of biological experiments.

Features of the four channel microinjection pump in push-pull mode
Main functions of the system
Working mode: infusion, extraction, infusion before extraction, extraction before infusion, five consecutive modes to choose from
Parameter setting function: Different working parameters can be set for each of the four channels separately
Operation control function: It can control each actuator to work separately, and can also control up to four actuators to work simultaneously or in a time-sharing manner
Channel copying function: allows all channel actuators to work according to the parameters of the copied channel
Delay start function: It can control the delay time for the execution mechanism of each channel to start working separately
Power off memory function: After powering on again, you can choose whether to continue working according to the state before power off
Traffic jam protection function: When an actuator is accidentally stopped from infusion or extraction, the system will sound a horn alarm and stop working
External control function: Receive pulse signals and control the start stop state. Each channel has two OC gate outputs to indicate the start stop and directional status of the channel's actuator
Each channel has two OC gate outputs to indicate the start stop and directional status of the channel's actuator
Communication function: With RS485 communication interface, it can be controlled through the background of the upper computer

Main functions of each channel
Syringe selection function: Different manufacturers and specifications of syringes can be selected from the list
Syringe customization function: Users can customize and store the inner diameter values of four sets of syringes for a single channel
Operation parameter setting function: Multiple parameters including dispensing volume, infusion time, extraction time, interval time, and dispensing frequency can be set
Display mode selection function: The main work interface can select to display different parameters: liquid volume, flow rate, linear velocity
Fast forward/rewind function: Full speed infusion or extraction of liquid
Flow correction function: Through the correction program, more accurate liquid volume can be allocated
