Overview
The LeadFluid TYD01-02 is a high-precision, micro-volume benchtop syringe pump engineered for demanding laboratory fluid handling applications. It operates on a stepper motor–driven linear actuation principle, converting rotational motion into precise axial displacement of the syringe plunger via a high-rigidity lead screw mechanism. This electromechanical architecture ensures deterministic volumetric delivery with minimal hysteresis and mechanical backlash—critical for applications requiring nanoliter-scale dosing accuracy over extended operation cycles. Designed for integration into analytical workflows—including HPLC sample introduction, microfluidic chip priming, electrophysiology perfusion, and controlled reagent addition in kinetic assays—the TYD01-02 delivers traceable, repeatable flow performance across six orders of magnitude (from sub-nanoliter to milliliter-per-minute regimes), without requiring recalibration between syringe sizes.
Key Features
- 5-inch high-resolution color LCD touchscreen interface with intuitive graphical navigation, supporting multi-language display and real-time parameter visualization (flow rate, infused volume, elapsed time, direction, status)
- Dual-syringe mounting capability: accommodates two independent syringes simultaneously (plastic or glass), with compatible volumes spanning 10 µL to 60 mL
- High-strength aerospace-grade angular contact ball bearings replace conventional bronze bushings in the lead screw assembly—reducing wear, extending service life by >3×, and maintaining positional fidelity under continuous duty
- Robust electromagnetic compatibility (EMC): validated for stable operation in environments with electrostatic fields up to 20 kV/m, making it suitable for use near mass spectrometers, electron microscopes, and high-voltage electrophoresis rigs
- Five operational modes: Infuse, Withdraw, Infuse-Withdraw, Continuous, and Standby—each configurable with programmable ramp profiles, step intervals, and pause conditions
- Integrated safety logic: automatic stall detection, occlusion pressure monitoring (via load sensing), syringe ejection prevention, and audible/visual alarm triggers upon abnormal resistance or motor stall
Sample Compatibility & Compliance
The TYD01-02 supports standard Luer-lock and Luer-slip syringes from major manufacturers (e.g., BD, Hamilton, SGE, Ito), with built-in calibration tables for over 40 preloaded syringe models. Users may also define custom syringe geometry (barrel inner diameter, plunger travel length) to ensure accurate volume-to-displacement mapping. While not certified for clinical or GMP manufacturing use, the device conforms to IEC 61000-4-2 (ESD immunity), IEC 61000-4-3 (radiated RF immunity), and IEC 61000-4-4 (electrical fast transient immunity). Its firmware architecture supports audit-ready operation when deployed within GLP-compliant laboratories—data logging timestamps, user ID tagging, and mode-change history are retained in non-volatile memory.
Software & Data Management
The pump communicates via isolated RS-485 serial interface compliant with Modbus RTU protocol (slave ID configurable, baud rates 9.6–115.2 kbps), enabling seamless integration with LabVIEW, MATLAB, Python (PyModbus), PLCs, and SCADA systems. Optional PC software provides script-based sequence programming, real-time flow monitoring graphs, CSV export of time-stamped volumetric data, and batch parameter saving. All configuration changes and runtime events—including start/stop commands, error codes, and syringe load adjustments—are logged with ISO 8601 timestamps and retained for ≥10,000 entries. For regulated environments, optional firmware enables 21 CFR Part 11–compatible electronic signatures and role-based access control (admin/operator modes).
Applications
- Controlled infusion in patch-clamp and calcium imaging experiments, where stable sub-µL/min perfusion minimizes cellular stress
- Automated sample loading for capillary electrophoresis and microchip-based CE systems
- Gradient solvent delivery in preparative chromatography setups requiring low-pulsation, pulseless flow
- Time-resolved reagent injection in stopped-flow spectroscopy and enzyme kinetics studies
- Calibration standard delivery for flow cytometer sheath fluid systems and particle counting instruments
- Long-duration drug release profiling in biomaterial dissolution testing (ISO 10993-12 compliant protocols)
FAQ
What syringe types and sizes are supported?
Standard Luer-lock and Luer-slip syringes from 10 µL to 60 mL capacity, including glass, polypropylene, and PTFE-barrel variants. Predefined calibration profiles exist for BD, Hamilton, and SGE models; custom diameters can be entered manually.
Does the pump support bidirectional flow control?
Yes—infuse, withdraw, and infuse-withdraw modes allow full reversal of plunger direction with programmable dwell times and flow rate transitions.
Can multiple TYD01-02 units be daisy-chained via RS-485?
Yes—up to 32 devices can share a single RS-485 bus using unique Modbus slave IDs; termination resistors and proper grounding are required for reliable multi-drop communication.
Is firmware update capability available?
Firmware updates are performed via USB-C port using vendor-provided utility software; version history and checksum verification are included for traceability.
What power input specifications does the unit require?
Universal AC input: 100–240 VAC, 50/60 Hz, with internal switching power supply delivering stable 24 VDC to the motor driver—no external power adapter needed.
