LSP04-1Y Four-Channel Laboratory Syringe Pump
Professional four-channel laboratory syringe pump with 304 stainless steel construction and LCD display. All four channels run synchronously under a single set of parameters, driven by microprocessor-controlled stepper motors, with multiple operat...
Overview
The LSP04-1Y Four-Channel Laboratory Syringe Pump delivers precise parallel fluid handling for demanding laboratory applications. The instrument drives four syringes in parallel under a single set of parameters (flow rate, volume, mode); channels are not individually programmable. Construction uses 304 stainless steel for chemical compatibility and long-term durability. Important: This product is designed for laboratory research only and is not intended for clinical applications.
Key Features
- Four parallel channels, synchronized under a single set of control parameters (not individually programmable)
- 304 stainless steel housing for chemical resistance
- 128×64 LCD display showing parameters and operational status
- Digital membrane keypad with rotary encoder for precise control
- Microprocessor-controlled 16-subdivision stepper motor with screw drive and synchronous belt transmission
- Maximum linear thrust of 280N for handling high-viscosity fluids and large-volume syringes
- RS485 communication bus for computer integration and remote control
- Multiple operating modes: infusion, withdrawal, infusion-then-withdrawal, withdrawal-then-infusion, and continuous operation
Applications
Ideal for pharmaceutical research, chemical synthesis, microfluidics, cell culture perfusion, drug delivery studies, and automated liquid handling protocols where the same flow profile is needed across multiple samples in parallel. For experiments that require different flow rates, timing sequences, or sequential per-channel dispensing, see the TSP01-08 Multi-Channel Independent Control Split Syringe Pump.

Can each of the four channels be controlled independently (different flow rates or sequential dispensing)?
No. The LSP04-1Y drives all four channels in parallel under a single set of control parameters (flow rate, volume, and operating mode). It is designed for experiments where the same fluid-delivery profile is applied across multiple samples simultaneously. If you need per-channel independent control (different flow rates per channel, sequential per-channel dispensing, or independently timed infusion cycles), use the TSP01-08 Multi-Channel Independent Control Split Syringe Pump instead.
What is the maximum thrust force of this syringe pump?
The LSP04-1Y delivers a maximum linear thrust of ≤280N, making it suitable for handling high-viscosity fluids and large-volume syringes.
Can this pump be connected to a computer for automated control?
Yes, the pump features an RS485 communication bus, allowing integration with computer systems for remote control and automated operation.
What operating modes are available on this pump?
The pump offers multiple operating modes including infusion, withdrawal, infusion-then-withdrawal, withdrawal-then-infusion, and continuous operation, providing flexibility for various experimental protocols.
Can the RS485 interface enable per-channel sequencing — for example, channel 1 runs then stops, then channel 2, and so on?
No. The RS485 interface on this pump allows remote parameter setting and monitoring via computer, but all four channels remain synchronized under a single set of parameters. RS485 does not enable per-channel timing, independent start/stop, or sequential dispensing. For applications requiring independently sequenced channels controlled via external interface, the TSP01-08 Multi-Channel Independent Control Split Syringe Pump supports per-channel configuration.
Does this pump require a PC to be connected during a run?
No. Flow rate, volume, syringe size, and operating mode are all configured through the front-panel LCD and membrane keypad. Once a run is started, the pump operates standalone. The RS485 connection to a computer is optional — it enables remote control and monitoring but is not required for operation.
Where can I find connector specifications, pinout diagrams, and electrical specs for the RS485 port?
Connector types, pin assignments, voltage ranges, and isolation details for the RS485 interface are documented in the product user manual. Contact our team to request the manual if you need to verify electrical compatibility with an external controller or PLC before purchasing.
