LeadFluid YD02-01 Precision Single-Channel Syringe Pump

Overview

The LeadFluid YD02-01 is a high-precision, single-channel syringe pump engineered for accurate, repeatable microfluidic delivery and withdrawal in analytical, pharmaceutical, biotechnology, and academic laboratory environments. It operates on a stepper-motor-driven linear actuation principle, converting rotational motion into precise axial displacement of the syringe plunger. This electromechanical architecture ensures deterministic volumetric control without reliance on pressure feedback or closed-loop flow sensing—making it especially suitable for applications where pulseless, low-shear, and time-synchronized fluid handling is required, such as HPLC sample injection, microreactor feeding, electrophysiology perfusion, and controlled reagent dosing in assay development.

Key Features

• Single-channel design with programmable bidirectional operation: injection, withdrawal, injection-then-withdrawal, withdrawal-then-injection, and continuous cyclic mode.
• High-resolution 4.3-inch color TFT touchscreen interface with intuitive graphical workflow navigation and real-time animated plunger position display.
• Comprehensive syringe compatibility: built-in database covering major global manufacturers (e.g., Hamilton, BD, Terumo, SGE) and standard glass/plastic syringes from 10 µL to 140 mL; user-definable syringe inner diameter input for custom hardware.
• Adjustable linear force (1–100% of maximum), enabling safe operation across fragile capillaries and high-viscosity media while maintaining mechanical integrity.
• Integrated safety logic including occlusion detection, stall alarm, and automatic stop on abnormal load conditions—critical for unattended overnight operation.
• RS485 serial interface compliant with MODBUS RTU protocol for seamless integration into automated lab systems, SCADA platforms, or custom PC-based control software.
• External TTL-level digital I/O for hardware-triggered start/stop and direction reversal—enabling synchronization with spectrometers, detectors, or robotic liquid handlers.
• Full parameter retention after power loss via non-volatile memory; configurable screen lock, key silence mode, and adjustable display brightness for ergonomic long-term use.

Sample Compatibility & Compliance

The YD02-01 accommodates a wide range of syringe materials—including borosilicate glass, polypropylene, and PTFE-coated barrels—supporting compatibility with aqueous, organic, mildly corrosive, and low-volatility solvents. Its all-metal enclosure features electrostatic-dissipative and corrosion-resistant coating, meeting basic environmental robustness requirements for ISO 13485-aligned cleanroom-adjacent workflows. While not certified for GMP manufacturing, the device supports GLP-compliant documentation through MODBUS data logging and external timestamped acquisition. Its deterministic open-loop control architecture inherently satisfies traceability requirements under FDA 21 CFR Part 11 when paired with validated third-party data capture systems that enforce audit trails and electronic signatures.

Software & Data Management

The pump operates autonomously via onboard firmware but supports external command and monitoring via MODBUS RTU over RS485. Users may implement custom control scripts (Python, LabVIEW, MATLAB) to schedule multi-step protocols, trigger events based on sensor inputs, or aggregate volumetric output with analytical instrument timestamps. All operational parameters—including target volume, flow rate, direction, and syringe geometry—are stored in non-volatile memory and persist across power cycles. Optional PC software (available separately) enables batch method storage, CSV export of run logs, and real-time remote status polling—facilitating routine QC recordkeeping and cross-instrument protocol harmonization.

Applications

• HPLC and UHPLC autosampler priming and low-flow gradient delivery
• Controlled infusion in patch-clamp and microdialysis setups
• Precise reagent addition in ELISA, PCR setup, and cell culture media supplementation
• Calibration fluid delivery for flow sensor validation (e.g., thermal mass flow meters)
• Microfluidic chip actuation in droplet generation and laminar mixing experiments
• Long-duration solvent exchange in material synthesis reactors
• Automated titration systems requiring sub-microliter dosing resolution

FAQ

Does the YD02-01 support closed-loop flow feedback or pressure sensing?
No—it is an open-loop, position-controlled syringe pump. Flow accuracy relies on calibrated syringe geometry and motor step fidelity, not real-time flow measurement.
Can it be integrated into a Windows-based LIMS or ELN system?
Yes, via MODBUS RTU over RS485 using standard industrial communication drivers; custom middleware may be required for direct LIMS API ingestion.
What is the minimum resolvable volume increment at the lowest flow rate?
At 0.001 µL/min and using a 10 µL syringe, the theoretical minimum dispensed volume per motor step is ~0.00016 µL—subject to syringe manufacturing tolerances and fluid compressibility.
Is the device compatible with explosion-proof or intrinsically safe environments?
No—the YD02-01 lacks ATEX, IECEx, or UL Class I Div 2 certification and is intended for general laboratory use only.
How is calibration performed, and is NIST-traceable verification available?
Users perform volumetric calibration via gravimetric or timed-collected volume methods; LeadFluid provides calibration procedure guidance but does not supply NIST-traceable certificates.
