Chemyx Fusion 101 Dual-Channel Syringe Pump

Overview

The Chemyx Fusion 101 is a dual-channel, microprocessor-controlled syringe pump engineered for high-precision fluid delivery in demanding laboratory environments. It operates on the principle of linear motor-driven plunger displacement, enabling continuous, pulseless flow across an exceptionally wide dynamic range—from nanoliter-per-minute infusion for electrospray ionization (ESI) source conditioning to milliliter-per-minute reagent feeding in continuous-flow reactors. Designed with a robust aluminum chassis and calibrated force feedback loop, the Fusion 101 delivers stable volumetric output under variable backpressure conditions typical in microfluidics, capillary electrophoresis, and closed-loop perfusion systems. Its architecture complies with fundamental requirements for GLP-compliant instrumentation, including deterministic command execution, non-volatile parameter storage, and traceable operational logging when integrated with validated software.

Key Features

• Dual independent channels with synchronized or asynchronous operation—enabling co-infusion, gradient mixing, or sequential dosing without hardware modification
• 4.3-inch monochrome LCD touchscreen interface with intuitive icon-based navigation and real-time flow visualization
• Programmable flow profiles including ramped, stepped, and segmented protocols—supporting multi-stage reaction initiation and time-resolved pharmacokinetic studies
• Acoustic alert system with configurable thresholds for flow deviation, syringe empty detection, and motor stall events
• Quiet-mode firmware optimization reducing audible motor noise below 35 dB(A), suitable for shared lab spaces and neurophysiology recording suites
• Universal syringe compatibility: accommodates glass, polypropylene, and stainless-steel barrels from 0.5 µL to 60 mL capacity with automatic diameter recognition via encoder calibration
• RS232 serial and TTL trigger I/O ports for integration into automated workflows—compatible with LabVIEW, Python (PySerial), and MATLAB instrument control toolboxes

Sample Compatibility & Compliance

The Fusion 101 supports chemically inert fluid handling across aqueous, organic, and mildly corrosive media—including DMSO, acetonitrile, PBS buffers, and low-concentration acid/base solutions—when paired with appropriate syringe materials and PTFE/PEEK tubing. It meets mechanical safety standards per UL 61010-1 and carries CE marking for EMC Directive 2014/30/EU. While not certified as medical-grade equipment, its accuracy and repeatability performance align with ASTM D3418-21 (for viscosity standardization setups) and USP <1058> guidance for analytical instrument qualification. Audit trail functionality is enabled through external software logging, supporting 21 CFR Part 11–compliant data integrity frameworks when deployed with validated third-party acquisition platforms.

Software & Data Management

Chemyx provides free PC-based Fusion Control Software (v3.2+) with native support for Windows 10/11 and macOS 12+. The application enables full remote configuration, real-time monitoring of plunger position and elapsed time, and export of timestamped CSV logs containing flow rate, volume dispensed, and error codes. Scripting interfaces allow batch protocol loading and conditional triggering based on external TTL signals—essential for coupling with mass spectrometers, fluorescence detectors, or temperature-controlled reaction blocks. All parameter changes are recorded with user ID, timestamp, and previous/modified values—facilitating retrospective review during internal QA audits or regulatory inspections.

Applications

• Electrospray Ionization (ESI) source infusion for LC-MS method development and sensitivity optimization
• Controlled precursor delivery in electrospinning setups for reproducible nanofiber morphology
• Chronic intracerebral or intrathecal drug administration in rodent neuroscience models
• Microdialysis probe perfusion with sub-microliter bolus precision in awake-behaving assays
• Stem cell differentiation media exchange in bioreactor-integrated organoid culture platforms
• Automated reagent injection into microreactors for kinetic studies under residence time control
• Calibration standard delivery for gravimetric and photometric assay validation

FAQ

Does the Fusion 101 support syringe pump synchronization with external analytical instruments?
Yes—via TTL input/output lines and RS232 commands, it can be triggered by detector signals (e.g., UV absorbance peaks) or initiate data acquisition upon volume threshold crossing.
What is the maximum backpressure tolerance for this pump?
While not rated for pressure specification, empirical testing shows stable operation up to ~120 psi with 26-gauge stainless steel needles and 10 cm PEEK tubing at 1 mL/min using water—actual limits depend on syringe type, fluid viscosity, and tubing geometry.
Is firmware update capability available?
Yes—field-upgradable firmware is distributed through Chemyx’s secure customer portal and requires no hardware modification.
Can the Fusion 101 operate unattended for extended periods?
It features thermal shutdown protection, end-of-syringe detection, and watchdog timer circuitry—enabling reliable overnight operation when configured with appropriate syringe volume and flow profile.
Are validation documents (IQ/OQ/PQ templates) provided?
Chemyx supplies generic IQ/OQ test protocols aligned with ISO/IEC 17025 principles; site-specific PQ must be developed per application and process requirements.
