Ultron UC-3282 High-Performance HPLC High-Pressure Solvent Delivery Pump

Overview

The Ultron UC-3282 is a high-precision, high-pressure solvent delivery pump engineered for use in analytical and semi-preparative liquid chromatography systems. It operates on the principle of dual-piston serial reciprocating displacement, delivering stable, pulse-minimized flow across a wide dynamic range. Unlike conventional parallel-piston designs, the serial architecture eliminates one pair of check valves—reducing potential failure points by approximately 50% and minimizing dead volume. The pump integrates electronic pressure pulsation suppression (EPPS), a proprietary control strategy that dynamically adjusts motor torque and piston timing to counteract compressibility effects and valve dynamics in real time. This approach replaces mechanical dampeners, thereby improving long-term stability, reducing system dwell volume, and enhancing baseline integrity in gradient elution. Designed for compatibility with standard HPLC and UHPLC-compatible tubing and fittings, the UC-3282 supports operation up to 40 MPa (5800 psi), making it suitable for both conventional silica-based columns and sub-2 µm particle-packed stationary phases.

Key Features

• Electronic pressure pulsation suppression (EPPS) technology—eliminates mechanical dampers and reduces flow ripple to <0.1 MPa under defined load conditions.
• Dual-piston serial reciprocating architecture—reduces check valve count by 50% versus parallel configurations, lowering maintenance frequency and increasing uptime.
• High-resolution DC servo motor with optical encoder feedback—enables sub-microliter flow resolution and near-silent operation (<45 dB(A) at 1 m).
• Configurable flow range via interchangeable pump heads: 10 mL head for analytical-scale applications (0.001–9.999 mL/min); 50 mL head for semi-preparative workflows (0.01–49.99 mL/min).
• Real-time flow compensation algorithms—automatically adjust for mobile phase compressibility, column backpressure variation, and check valve response latency.
• RS-232 interface compliant with ASTM E1382-95 and ISO/IEC 11801 standards—enables bidirectional communication with third-party chromatography data systems (CDS) and native Ultron workstations.
• User-configurable pressure limit protection—prevents column damage or seal failure during blockage events or viscosity spikes.

Sample Compatibility & Compliance

The UC-3282 is compatible with all common HPLC-grade solvents—including aqueous buffers, acetonitrile, methanol, tetrahydrofuran, and chlorinated hydrocarbons—provided they meet material compatibility requirements for stainless steel 316L wetted parts and sapphire/ruby check valves. It conforms to IEC 61010-1:2010 for laboratory equipment safety and meets electromagnetic compatibility (EMC) requirements per EN 61326-1:2013. For regulated environments, the pump supports audit-trail-capable GLP functionality—including cumulative solvent usage logging with timestamping—aligning with FDA 21 CFR Part 11 data integrity expectations when paired with compliant CDS software. While not certified for GMP manufacturing, its design adheres to principles outlined in USP and ISO 17025 for method validation robustness.

Software & Data Management

The UC-3282 communicates via ASCII-based RS-232 protocol using standardized command sets (e.g., “FLO”, “PRE”, “STA”, “STO”) compatible with Agilent ChemStation, Waters Empower, and open-source platforms such as OpenLab CDS. Firmware supports firmware-upgradable parameter tables for custom solvent compressibility coefficients and pressure-flow calibration curves. All operational parameters—including total solvent volume dispensed, elapsed runtime, and maximum pressure events—are logged internally and exportable as CSV files. No cloud connectivity or proprietary drivers are required; integration relies solely on industry-standard serial protocols and does not necessitate vendor-specific middleware.

Applications

• Analytical reversed-phase HPLC for pharmaceutical impurity profiling per ICH Q2(R2) guidelines.
• Semi-preparative purification of natural products and synthetic intermediates at flow rates up to 49.99 mL/min.
• Method development workflows requiring seamless transition between isocratic and multi-step gradient elution.
• Integration into multi-pump gradient systems—supports binary high-pressure mixing (with optional second UC-3282 unit) or quaternary low-pressure blending (via external proportioning valve).
• Stability-indicating assays where flow precision (<0.1% RSD) directly impacts retention time reproducibility and peak area linearity.
• Academic research labs performing LC-MS coupling where low pulsation and minimal dwell volume improve ionization efficiency and retention time alignment.

FAQ

Can the UC-3282 be used in UHPLC systems?
Yes—when equipped with the 10 mL pump head and operated within its 40 MPa pressure rating, it meets the hydraulic performance requirements for many UHPLC methods, though dwell volume should be verified against system-specific specifications.
Is GLP-compliant data logging enabled by default?
Yes—the instrument records cumulative solvent volume with date/time stamps automatically; however, full 21 CFR Part 11 compliance requires integration with a validated chromatography data system that enforces electronic signatures and audit trails.
Does the pump support gradient programming natively?
No—the UC-3282 is a single-channel isocratic pump; gradient capability requires external hardware (e.g., high-pressure mixer or low-pressure proportioning valve) and coordination via host CDS software.
What maintenance intervals are recommended for check valves and seals?
Under typical analytical use (≤20 MPa, aqueous/organic solvents), sapphire/ruby check valves require inspection every 6 months; piston seals are rated for ≥5,000 hours of continuous operation per manufacturer specification.
Is firmware update capability available without service technician involvement?
Yes—firmware updates are performed via RS-232 using publicly documented hex-file upload commands; no proprietary utility software is required.
