Sanotac SP1030 Preparative High-Pressure Solvent Delivery Pump (100 mL Head, 30 MPa)

Overview

The Sanotac SP1030 Preparative High-Pressure Solvent Delivery Pump is an engineered solution for demanding preparative liquid chromatography (Prep-LC), flash chromatography, and process-scale solvent delivery applications requiring precise, stable, and reproducible flow under high backpressure conditions. Designed around a dual-piston serial architecture with floating piston technology, the SP1030 dynamically compensates for solvent compressibility and refilling lag—critical factors influencing baseline stability and gradient fidelity at elevated pressures. Its microprocessor-controlled drive system delivers real-time chamber pressure feedback and employs cam-profile flow compensation to suppress pulsation, achieving ≤0.2 MPa pressure ripple across its operational range. With a maximum pressure rating of 30 MPa and a 100 mL displacement pump head, the SP1030 supports high-flow, high-load separations—including viscous mobile phases and packed columns up to 100 mm internal diameter—while maintaining flow accuracy of ±0.5% and repeatability (RSD) ≤0.1% across the full 0.01–100.00 mL/min range.

Key Features

• Dual-piston serial pumping mechanism with floating piston design for extended seal life and consistent high-pressure sealing performance
• Real-time cavity pressure feedback loop enabling dynamic correction of solvent compressibility and refill delay
• Cam-curve flow compensation algorithm minimizing flow pulsation and ensuring ultra-low baseline noise in UV/ELSD detection
• Multi-point flow calibration curve stored internally—valid across entire flow range without interpolation error
• 256×64 dot-matrix self-luminous LCD display with adjustable backlight and consistent color gamut across all viewing angles
• Open-protocol RS232 and USB interfaces compliant with standard SCPI command sets—enabling seamless integration with third-party chromatography data systems (CDS), LIMS, or custom automation platforms
• Ten user-programmable methods supporting time-based flow gradients, stepwise pressure ramps, and multi-segment flow profiles

Sample Compatibility & Compliance

The SP1030 is compatible with a broad spectrum of organic and aqueous mobile phases—including acetonitrile, methanol, THF, DMSO, and buffered saline solutions—when used with its standard 316L stainless steel pump head. Its wetted path materials meet general laboratory chemical resistance requirements per ASTM F2136 and ISO 10993-5 for non-implantable device testing. While not certified for GMP manufacturing environments out-of-the-box, the pump’s deterministic control logic, audit-ready parameter logging (via external software), and programmable method recall support GLP-compliant operation when deployed within validated Prep-LC workflows. Its open communication protocol facilitates compliance with FDA 21 CFR Part 11 requirements when paired with appropriate electronic signature and audit trail software layers.

Software & Data Management

The SP1030 does not include proprietary control software but provides full ASCII-based command-line control via RS232 or USB virtual COM port. All commands follow industry-standard SCPI syntax (e.g., :FLOW 50.00, :GRADIENT START 0.0 10.0), allowing integration with LabVIEW, Python (pySerial), MATLAB, or commercial CDS platforms such as Chromeleon, Empower, or OpenLAB. Flow, pressure, and status parameters are reportable in real time at 1 Hz resolution. Internal memory retains ten user-defined methods with timestamped execution logs—accessible via serial query—and supports firmware updates via USB mass storage mode.

Applications

• Preparative HPLC purification of pharmaceutical intermediates, natural products, and synthetic peptides
• High-flow flash chromatography for rapid compound library fractionation
• Process development studies requiring scalable flow-pressure profiles prior to pilot-scale transfer
• Supercritical fluid chromatography (SFC) co-solvent delivery when configured with compatible seals and check valves
• Automated reaction quenching and reagent addition systems where precise volumetric dosing under backpressure is required
• Calibration and challenge testing of high-pressure inline sensors (e.g., densitometers, refractometers)

FAQ

What is the maximum allowable pressure for continuous operation?
The SP1030 is rated for continuous operation up to 30 MPa when equipped with the standard 316L stainless steel pump head and operated within ambient temperature limits (10–35 °C).
Does the pump support gradient elution?
Yes—ten programmable methods support time-based flow rate changes and multi-step gradient profiles; however, solvent blending must be performed externally using a low-pressure mixing module or proportioning valve.
Is the communication protocol documented and publicly available?
Yes—Sanotac provides a complete SCPI command reference manual upon request, including error codes, query syntax, and timing specifications for deterministic synchronization.
Can the SP1030 be integrated into a GMP-regulated environment?
It can serve as a qualified component within a GMP system when combined with validated software, change control procedures, and periodic performance verification per USP or ICH Q7 Annexes.
What maintenance intervals are recommended for the pump seals and check valves?
Under typical Prep-LC usage (≤25 MPa, aqueous/organic solvents), floating piston seals require inspection every 1,500 operating hours; sapphire-faced check valves are rated for ≥5,000 hours before replacement.
