The dLSP501X split-type syringe pump offers high-precision, modular fluid control for a wide range of fluid handling applications. Designed for research and industry, this pump combines accurate, pulse-free flow delivery with intuitive control options and robust safety features.
Featuring a modular architecture to optimize lab space, the system includes a user-friendly 7" touch screen controller, with up to 4 independent syringe pump units. With an overall accuracy ≤±0.35%, these syringe pumps are suitable for the most demanding lab applications.
For advanced automation and remote operation, the PC software (sold separately) enables precise programming, method storage, and control of up to 10 syringe modules simultaneously.
General
The dLSP501X syringe pump is designed to deliver outstanding performance in precision dosing, dispensing, and continuous flow applications. With its modular split-type design to control each syringe unit independently, the system separates the compact drive unit from the control module, enabling greater flexibility in lab or production layouts. The intuitive 7-inch touchscreen interface provides effortless access to control settings and real-time monitoring, while advanced control options (including PC software and external PLC integration) offer seamless automation and scaling capabilities.
Choose between dLSP501S (syringe up to 250 µL), dLSP501L (syringe up to 1000 µL), and dLSP501W (syringe up to 60 mL) depending on your application needs.
Features
- Outstanding flow control: Ultra-fine linear resolution down to 0.6096 µm/min and flow rates as low as 0.0048 nL/min ensure smooth, pulse-free delivery
- Wide range of syringe compatibility: Supports syringes from 0.5 µL to 60 mL, including user-defined options
- Flexible control modes: Operate via the touch screen (up to 4 units), PC software (control up to 10 units independently), or PLC/external controller via RS485 with Modbus RTU protocol
- Multiple work modes: Infusion, withdrawal, alternating infusion/withdrawal, and programmable routines tailored to your workflow (PC software only)
- High-accuracy delivery: ±0.35% linear travel accuracy and ≤0.03% CV during rated travel
- Robust data integrity: Screen lock, multi-level user access, log records, and FDA 21 CFR Part 11 compliant electronic signatures ensure secure operation
- Programming capabilities: Define and store up to 100 parameter sets; create custom programs using the advanced editor (PC software, included with the pump)
- Compact & powerful: Small footprint of the drive units makes the system ideal for limited-space environments while maintaining strong linear force output (up to 100 N for dLSP501W)
For dLSP501S and dLSP501L, a four-channel base (sold separately) allows for quickly connection/disconnection and syringe units management in a compact space.
To control up to 10 syringe units from a PC, a dedicated software (sold separately) is available.
Whether your work involves microfluidics, life science research, analytical chemistry, or industrial dosing, the dLSP501X provides accurate, repeatable, and customizable flow control, ranging from nanoliters to milliliters, with full traceability and compliance-ready features.
Flow rates
These flow rates are given for standard syringe volumes and barrel IDs. Custom syringe sizes can be added from the controller or PC software for each syringe pump unit.
