Chu Ding Technology TYD01-01 Laboratory Syringe Pump

Overview

The Chu Ding Technology TYD01-01 Laboratory Syringe Pump is a precision electromechanical fluid delivery system engineered for repeatable, low-flow-rate volumetric control in research and quality-controlled laboratory environments. Based on stepper motor-driven linear actuation and calibrated syringe displacement, the pump operates on the principle of positive displacement—translating rotational motor steps into precise linear plunger movement. This architecture ensures deterministic flow profiles without reliance on pressure feedback or fluid property compensation, making it suitable for applications where temporal fidelity, pulseless delivery, and programmable bidirectional operation are critical. Designed for integration into automated workflows, the TYD01-01 supports both standalone benchtop use and system-level control via industry-standard digital interfaces.

Key Features

• High-resolution 4.3-inch color TFT display (480 × 272 pixels, 65K color depth) with intuitive graphical interface for rapid parameter configuration and real-time status visualization
• Dual-syringe capability supporting independent or synchronized operation across two syringes (0.01–60 mL volume range), enabling complex multi-fluid protocols such as gradient mixing or sequential reagent addition
• Five programmable operating modes: Infuse, Withdraw, Infuse-Withdraw, Withdraw-Infuse, and Continuous—each configurable with dwell times, flow rates, and cycle counts
• Micrometer-grade motion control: 0.15625 µm per microstep resolution and speed range from 0.5 µm/min to 150 mm/min, delivering sub-microliter accuracy over extended durations
• Adjustable mechanical push force up to 34 kgf, optimized for high-viscosity media and narrow-bore tubing while maintaining positional repeatability
• Comprehensive safety logic including occlusion detection, syringe disengagement monitoring, and audible/visual alarm activation upon fault conditions
• Full-metal enclosure rated for electromagnetic compatibility (EMC) in shared instrumentation labs; robust mechanical design minimizes vibration-induced flow deviation
• Integrated RS-485 port compliant with Modbus RTU protocol (slave mode), enabling seamless integration with PLCs, SCADA systems, or custom LabVIEW/Python control frameworks
• 24 V DC TTL-compatible external I/O for hardware-triggered start/stop and direction reversal—ideal for synchronization with spectrometers, detectors, or valve manifolds

Sample Compatibility & Compliance

The TYD01-01 accommodates standard Luer-lock and Luer-slip syringes from major manufacturers (e.g., BD, Hamilton, SGE), including glass, plastic, and stainless-steel variants. Users may define custom syringe inner diameters and stroke lengths within the firmware, ensuring accurate volume calculation regardless of barrel geometry. While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, the device’s deterministic behavior, audit-ready parameter logging (via external host), and hardware-enforced interlocks support alignment with GLP and GMP documentation requirements when deployed in validated workflows. Its wide input voltage range (100–240 V AC) and thermal management allow stable operation under variable utility conditions typical of academic and industrial core facilities.

Software & Data Management

The pump operates autonomously after local configuration but is fully controllable via ASCII command sets transmitted over RS-485. No proprietary software is required; integration relies on open Modbus register mapping (e.g., holding registers for target volume, rate, mode, and status flags). Third-party platforms—including MATLAB Instrument Control Toolbox, Python’s pymodbus library, and National Instruments DAQmx—can read real-time position, current mode, and error codes. All user-modifiable parameters are retained in non-volatile memory. For traceability, timestamped operational logs (start time, total dispensed volume, fault events) must be captured externally—consistent with ALCOA+ principles when paired with a compliant data acquisition system.

Applications

• Controlled reagent dosing in kinetic assays (e.g., enzyme inhibition studies, titration-based sensor calibration)
• Microfluidic chip priming and continuous perfusion in organ-on-chip and cell culture platforms
• Calibration fluid delivery for HPLC autosamplers and ICP-MS nebulizers
• Slow-rate infusion in pharmacokinetic modeling and dissolution testing (USP Apparatus 2/4)
• Multi-step synthesis automation where stoichiometric precision and timing synchronization are essential
• Environmental sample introduction in continuous-flow analyzers (e.g., nutrient analyzers, COD reactors)

FAQ

What syringe sizes are supported?
The TYD01-01 accepts syringes ranging from 10 µL to 60 mL. Both single- and dual-syringe configurations are supported, with manual diameter entry for non-standard barrels.
Is the pump compatible with regulatory-compliant data integrity practices?
While the device itself does not include built-in electronic signatures or audit trails, its Modbus interface enables full parameter logging and state capture by external validated systems meeting 21 CFR Part 11 or Annex 11 requirements.
Can the pump operate continuously for extended periods?
Yes—the thermal design and brushless stepper motor allow uninterrupted operation at speeds ≥1 mm/min for >72 hours, provided ambient temperature remains within 5–40 °C and relative humidity stays below 80% RH.
Does it support closed-loop flow feedback?
No. The TYD01-01 is an open-loop displacement controller. Flow rate accuracy depends on syringe calibration, fluid compressibility, and tubing elasticity; for pressure- or flow-critical applications, pairing with an inline flow sensor is recommended.
What power supply specifications are required?
It accepts universal AC input (100–240 V, 50/60 Hz) and requires no external transformer—suitable for global deployment without voltage conversion hardware.
