Teledyne ISCO X-Series High-Pressure Precision Syringe Pump

Overview

The Teledyne ISCO X-Series High-Pressure Precision Syringe Pump is an engineered solution for applications demanding ultra-stable, pulseless fluid delivery under extreme pressure and at nanoliter-scale flow rates. Based on positive displacement syringe actuation with precision stepper motor control and closed-loop feedback, the X-Series operates on the principle of volumetric displacement—where linear motion of a stainless-steel plunger within a calibrated syringe barrel directly defines delivered volume per step. This architecture eliminates check-valve-induced pulsation inherent in reciprocating piston pumps, enabling true laminar, continuous flow essential for sensitive analytical and process-critical operations. Designed and manufactured in the United States, each X-Series pump integrates a ruggedized pump head, thermally stable drive mechanism, and microprocessor-based controller capable of autonomous operation or seamless integration into automated laboratory or pilot-scale systems.

Key Features

• Ultra-high pressure capability up to 30,000 psi (2,068 bar), supporting supercritical CO₂, high-viscosity polymer melts, and aggressive chemical feedstocks.
• Nanoliter-level resolution: minimum incremental displacement as low as 2.5 nL (model-dependent), ensuring exceptional volumetric fidelity across wide dynamic flow ranges.
• Flow accuracy of ±0.3% of setpoint (65X model) to ±0.5% (larger models); pressure accuracy configurable to ±0.1% full scale with optional calibration.
• Pulseless, continuous flow profile—no check valves, no flow reversal, no pressure transients—ideal for electrochemical detection, column-based separations, and real-time reaction monitoring.
• Modular architecture supporting single-pump, dual-pump continuous flow, concentration gradient generation, dispensing, and multi-pump synchronization (up to four units).
• Chemically resistant wetted path composed of Nitronic 50 stainless steel, PTFE seals, and Hastelloy C-276 components—validated for compatibility with corrosive solvents, acids, bases, and supercritical fluids.
• Temperature-controlled variants available (up to 200 °C) for high-viscosity or thermally sensitive applications such as polymer processing and catalytic reaction studies.

Sample Compatibility & Compliance

The X-Series accommodates a broad spectrum of sample types—including aqueous and organic solvents, supercritical CO₂, molten polymers, slurries, and aggressive reagents—without degradation of performance or integrity of the fluid path. All standard configurations comply with general laboratory safety standards for electrical equipment (UL/CSA 61010-1) and electromagnetic compatibility (FCC Part 15, Class A). When deployed in regulated environments—such as pharmaceutical development labs or contract research organizations—the system supports audit-ready operation via optional time-stamped event logging, user-access controls, and electronic signature-capable software interfaces aligned with FDA 21 CFR Part 11 requirements. While not intrinsically rated for Class I Div 1 hazardous locations, explosion-proof (HLf) configurations are available upon request and certified to ATEX/IECEx standards.

Software & Data Management

Pump operation is managed via the embedded ISCO Pump Control Software (v5.x), offering intuitive configuration of flow profiles, pressure limits, ramp rates, and sequence-based protocols. The controller logs timestamped operational data—including actual flow rate, pressure, motor position, and error states—at user-defined intervals (down to 100 ms), exporting structured CSV files for traceability and post-processing. For integration into larger automation frameworks, native support includes RS-232 serial command protocol (SCPI-compliant), 0–5 V / 0–10 V analog input/output for external PID control, dry-contact triggers for DCS handshaking, and LabVIEW drivers with documented VI libraries. All firmware updates and configuration backups are performed via USB interface, ensuring version control and reproducibility across instrument fleets.

Applications

• Core Flooding & Reservoir Simulation: Delivers stable, low-flow-rate brine, surfactant, or CO₂ injection under reservoir-relevant pressures and temperatures; compatible with triaxial cells and acoustic emission monitoring setups.
• Supercritical Fluid Processing: Serves as primary delivery for SC-CO₂ in extraction, impregnation, particle formation (RESS, SAS), and catalytic reactions—leveraging precise pressure regulation and optional chiller interface for CO₂ phase stabilization.
• HPLC & LC-MS Auxiliary Delivery: Supplies derivatization reagents, mobile phase modifiers, or post-column additives with zero pulsation—reducing baseline noise and improving signal-to-noise ratio in mass-sensitive detection.
• Catalyst & Reagent Dosing: Enables stoichiometrically accurate, programmable addition in kinetic studies, flow chemistry reactors, and asymmetric synthesis—critical where over- or under-dosing compromises selectivity or yield.
• Materials Science & Polymer Engineering: Feeds viscous prepolymers, nanocomposite dispersions, or foaming agents into extruders, rheometers, or microfluidic platforms under controlled shear and thermal conditions.
• Pharmaceutical Dispensing & Formulation: Supports high-precision aliquoting of APIs, excipients, or sterile solutions across variable volumes (nL to mL), meeting USP analytical instrument qualification guidelines.

FAQ

What distinguishes the X-Series from conventional reciprocating piston pumps?
Unlike check-valve-dependent designs, the X-Series uses direct syringe displacement without fluid reversal—eliminating pulsation, minimizing dead volume, and delivering superior long-term flow stability and accuracy.
Can the X-Series be integrated into a PLC-controlled pilot plant?
Yes—via dry-contact I/O, analog voltage signals, or Modbus RTU (with optional adapter), enabling deterministic start/stop, flow setpoint modulation, and fault reporting within industrial control architectures.
Is remote monitoring and control supported over Ethernet or Wi-Fi?
Native Ethernet is not included, but third-party serial-to-Ethernet gateways (e.g., Lantronix UDS-10) are widely deployed and validated for secure remote access using standard TCP/IP protocols.
How is calibration traceability maintained for regulatory submissions?
Each unit ships with NIST-traceable calibration certificates for flow and pressure; optional annual recalibration services include full uncertainty budgets and ISO/IEC 17025-compliant documentation.
Are custom wetted materials available for highly reactive chemistries?
Yes—custom configurations with sapphire plungers, titanium barrels, or specialized elastomers (e.g., Kalrez, Chemraz) can be engineered and qualified per application-specific compatibility testing protocols.
