LeadFluid TYD02-02 Dual-Channel Laboratory Syringe Pump

Overview

The LeadFluid TYD02-02 is a dual-channel, high-precision laboratory syringe pump engineered for reproducible micro- to macro-scale fluid delivery in research and quality control environments. It operates on a stepper motor-driven linear actuation principle, converting rotational motion into precise axial displacement of syringe plungers via a high-rigidity lead screw assembly supported by aerospace-grade angular contact bearings—eliminating backlash and wear associated with conventional bronze bushings. This mechanical architecture ensures long-term positional stability and sub-micron resolution (0.156 µm per microstep), critical for applications demanding strict volumetric fidelity across wide dynamic ranges—from nanoliter-per-minute infusions in single-cell electrophysiology to milliliter-per-minute reagent dispensing in automated assay platforms. The pump’s open-loop control system is calibrated against traceable volumetric standards, delivering verified accuracy and repeatability better than ±0.35% under defined operating conditions (stroke >30% of maximum). Its fully isolated metal chassis, electrostatically dissipative coating, and certified EMC immunity enable stable operation in high-voltage or RF-intensive lab settings, including electrospray ionization (ESI) source coupling and plasma-enhanced reaction chambers.

Key Features

• Dual independent channels support simultaneous or asynchronous operation of two syringes—plastic or glass—with capacity ranging from 10 µL to 140 mL
• 4.3-inch full-color TFT touchscreen with intuitive GUI, real-time animated plunger position display, and multi-parameter overlay (delivered volume, residual volume, flow rate, direction, syringe ID)
• High-torque linear drive system delivering >20 kgf rated force, adjustable from 1% to 100% to accommodate viscous or high-backpressure fluids
• RS485 serial interface compliant with Modbus RTU protocol for seamless integration into PLC-controlled workflows, SCADA systems, or custom LabVIEW/Python automation suites
• Comprehensive safety logic including occlusion detection, stall monitoring, and automatic emergency stop upon load anomaly or command timeout
• Full parameter persistence across power cycles; retains all user-defined settings, calibration offsets, and operational history
• Configurable I/O signals: two optically isolated digital outputs (run status, direction), two isolated digital inputs (start/stop, direction toggle), enabling hardware-triggered sequencing
• Wide input voltage range (AC 100–240 V, 50/60 Hz) and internal thermal management ensure uninterrupted operation in global laboratory infrastructures

Sample Compatibility & Compliance

The TYD02-02 accommodates standard Luer-lock and Luer-slip syringes from major manufacturers (e.g., Hamilton, BD, SGE, Thermo Fisher), with built-in libraries for over 30 common models. Users may also define custom syringes by entering inner diameter (ID) with ±0.001 mm precision—essential for non-standard or specialty glassware. The pump complies with IEC 61326-1 (EMC for laboratory equipment) and meets EN 61010-1 safety requirements for electrical equipment used in measurement, control, and laboratory use. While not certified for GMP manufacturing environments out-of-the-box, its deterministic control behavior, audit-ready parameter logging, and Modbus-based data traceability support validation protocols aligned with FDA 21 CFR Part 11 Annex 11 expectations when deployed within documented SOPs.

Software & Data Management

No proprietary software installation is required—the TYD02-02 operates autonomously via front-panel controls. However, its Modbus RTU interface enables bidirectional communication with third-party platforms for remote configuration, real-time telemetry streaming, and batch-run scripting. All operational parameters—including flow profiles, pause points, volume targets, and calibration coefficients—are stored in non-volatile memory with timestamped change logs. When integrated into networked lab infrastructure, the pump supports periodic CSV export of run metadata (start time, duration, delivered volume, error codes) via external gateway devices. For GLP-compliant usage, users may implement external database logging using Modbus TCP-to-RTU bridges, satisfying requirements for electronic record integrity and operator accountability.

Applications

• Controlled reagent addition in kinetic studies (e.g., stopped-flow spectroscopy, enzyme kinetics)
• Continuous infusion in microfluidic chip priming, droplet generation, and organ-on-chip perfusion
• Calibration fluid delivery for HPLC, IC, and CE systems requiring trace-level standard introduction
• Electrospinning and electrospray deposition where stable nanoliter-rate solvent feed is mandatory
• Automated sample preparation workflows interfaced with autosamplers or robotic liquid handlers
• In vivo microinjection setups requiring programmable bolus or ramped delivery profiles
• Material science applications such as controlled polymer precursor injection in 3D bioprinting scaffolds

FAQ

What syringe sizes are supported?
The TYD02-02 accepts syringes from 10 µL to 140 mL capacity. Internal databases include common models from Hamilton, BD, and SGE; custom syringes can be added by specifying internal diameter to three decimal places.
Does the pump support closed-loop feedback or pressure sensing?
No—it operates in open-loop mode with high-fidelity position control. Pressure monitoring requires external transducers connected via analog I/O modules or third-party DAQ systems.
Can it be integrated into a GMP-regulated environment?
Yes, provided validation documentation (IQ/OQ/PQ), change control procedures, and electronic audit trails are implemented externally using its Modbus interface and timestamped internal logs.
Is firmware upgradable in the field?
Firmware updates are performed via USB flash drive using LeadFluid’s official utility—no disassembly or service intervention required.
What is the warranty and service support coverage?
LeadFluid provides a 24-month limited warranty covering parts and labor for defects in materials and workmanship under normal laboratory use conditions.
