Chemyx Fusion 6000-X High-Pressure Syringe Pump

Overview

The Chemyx Fusion 6000-X is a high-precision, single-channel, high-pressure syringe pump engineered for demanding microfluidic and precision fluid delivery applications in research laboratories and regulated industrial environments. Based on stepper motor-driven linear actuation and calibrated volumetric displacement, the Fusion 6000-X delivers programmable, pulseless flow across an exceptionally wide dynamic range—from ultra-low nanoliter-per-minute regimes (0.0001 µL/min) to high-volume bolus delivery (up to 408 mL/min). Its robust architecture supports sustained operation under elevated backpressure conditions, making it suitable for applications involving viscous solutions, suspensions, gels, and semi-solid formulations where conventional peristaltic or low-force syringe pumps fail. The system operates on the principle of controlled plunger displacement within a rigid syringe barrel—ensuring direct correlation between motor step count, syringe geometry, and delivered volume—thereby enabling traceable, reproducible dosing without reliance on indirect pressure feedback loops.

Key Features

• High-force linear actuator delivering up to 700 lb (318 kg) of push/pull force, enabling stable flow against backpressures exceeding 10,000 psi in compatible syringe configurations
• Full bidirectional control with programmable injection and withdrawal modes, supporting complex infusion-withdrawal protocols essential for dialysis, sampling, and closed-loop microreactor operation
• Wide syringe compatibility: accommodates standard glass, polypropylene, and stainless-steel syringes from 0.5 µL micro-syringes to 300 mL industrial barrels
• 4.3-inch full-color capacitive touchscreen interface with intuitive graphical workflow navigation, real-time flow visualization, and on-device parameter logging
• Dual communication interfaces—RS232 and TTL—enabling seamless integration into automated lab platforms, PLC-controlled reactors, and custom-built experimental rigs
• Thermally stabilized housing design minimizes thermal drift during extended operation; optional external temperature monitoring modules support ambient or heated syringe chamber integration

Sample Compatibility & Compliance

The Fusion 6000-X is compatible with a broad spectrum of sample types—including aqueous buffers, organic solvents, polymer melts, cell-laden hydrogels, nanoparticle colloids, and shear-thinning biologics—provided appropriate syringe material selection (e.g., stainless steel for aggressive solvents or high-pressure stability). It meets mechanical and electrical safety requirements per UL 61010-1 and IEC 61010-1. While not inherently FDA 21 CFR Part 11 compliant as a standalone device, its RS232/TTL interface supports external audit-trail-enabled software systems used in GLP/GMP environments. Protocol execution logs, time-stamped parameter sets, and error codes can be exported for regulatory documentation. The pump conforms to ISO 8573-1 for compressed air–free operation and requires no pneumatic infrastructure—reducing contamination risk in sterile or cleanroom workflows.

Software & Data Management

Chemyx provides FusionLab™ PC software (Windows-compatible) for advanced protocol scripting, multi-step ramping, real-time graphing, and CSV-based data export. Users can define time-dependent flow profiles, trigger external devices via TTL output signals, and synchronize pump events with analytical instrumentation (e.g., mass spectrometers, UV-Vis detectors). All parameter changes are timestamped and stored locally on the device’s non-volatile memory. Firmware updates preserve calibration constants and support backward-compatible configuration files. For enterprise deployment, FusionLab supports batch import/export of method templates and integrates with LabArchives ELN and Benchling via API extensions. Audit trail functionality—including user login tracking and modification history—is available when operated under validated IT infrastructure meeting ALCOA+ principles.

Applications

• Mass spectrometry sample introduction—especially nanoESI and chip-based interfaces requiring stable sub-µL/min flows
• Microfluidic device priming, reagent loading, and gradient generation in organ-on-chip and droplet-based platforms
• In vivo microinjection in neuroscience and developmental biology, including intracerebral, intravitreal, and intraspinal delivery
• Controlled feeding of continuous-flow chemical reactors and catalytic microreactors operating under elevated pressure
• Electrospinning and electrospraying processes requiring precise polymer solution metering at variable voltage conditions
• Stem cell encapsulation and 3D bioprinting workflows where shear-sensitive bioinks demand laminar, pulsation-free extrusion
• Pharmacokinetic and toxicology studies involving repeated low-dose administration in rodent models

FAQ

What syringe materials are supported, and how do I select the appropriate one for my application?

Glass syringes are recommended for high-precision volumetric work with non-corrosive aqueous/organic solutions; stainless-steel syringes are required for high-pressure (>1,000 psi), high-viscosity, or chemically aggressive media; plastic syringes (e.g., polypropylene) are suitable for disposable, low-cost, or single-use protocols.
Can the Fusion 6000-X be integrated into a GMP-compliant manufacturing process?

Yes—when deployed with validated third-party software providing electronic signatures, change control, and audit trails, the pump satisfies functional requirements for Phase-appropriate process validation per ICH Q5, Q7, and Q9 guidelines.
Is temperature control built-in, or does it require external accessories?

The base unit does not include active heating/cooling; however, its mechanical design accommodates commercially available syringe heater-cooler jackets and supports analog input for external PID temperature controllers.
How is calibration performed, and is it traceable to NIST standards?

Factory calibration uses gravimetric measurement against NIST-traceable mass standards; users may perform verification checks using certified flow meters or timed gravimetric collection. Calibration certificates are provided with each unit.
Does the pump support multi-syringe or dual-pump synchronization?

The Fusion 6000-X is a single-channel system; synchronized dual-pump operation requires two units coordinated via TTL triggering or host PC software—Chemyx offers timing synchronization kits for sub-millisecond alignment.
