Sanotac AP0012 Analytical High-Pressure Solvent Delivery Pump with Titanium Pump Head

Overview

The Sanotac AP0012 Analytical High-Pressure Solvent Delivery Pump is an engineered precision fluidic actuator designed for demanding liquid chromatography applications—including HPLC, UHPLC, and preparative-scale separations—where stable, low-pulsation flow delivery at elevated pressures is critical. Built around a dual-piston series architecture with floating piston support, the AP0012 eliminates mechanical preload-induced wear on plunger assemblies and seal interfaces, thereby extending service life while maintaining metrological integrity over extended operational cycles. Its 10 mL titanium pump head and integrated titanium check valves provide exceptional chemical compatibility with aggressive solvents (e.g., concentrated acids, halogenated organics, and high-pH mobile phases), as well as superior resistance to corrosion and fatigue under sustained 42 MPa (6,090 psi) pressure loads. The pump operates on a closed-loop flow feedback principle, where real-time pressure and flow transduction—combined with adaptive motor torque compensation—ensures consistent volumetric displacement across its full 0.001–9.999 mL/min range.

Key Features

• Dual-piston series drive mechanism with dynamically balanced floating piston support—reduces radial loading on seals and extends mean time between maintenance (MTBM) by up to 3× versus fixed-bearing designs
• Titanium pump head (10 mL volume) and titanium inlet/outlet check valves—certified for continuous operation at ≤42 MPa and compatible with ASTM F136-grade biocompatible titanium alloy specifications
• Sub-microliter flow resolution: 0.001 mL/min increment with traceable calibration against NIST-traceable gravimetric standards
• Flow accuracy of ±0.1% or ±10 µL (whichever is greater) and repeatability (RSD) ≤0.1%—validated per ISO 5725-2:2019 guidelines for precision measurement systems
• Pressure pulsation <0.5 MPa across full flow and pressure range—measured using piezoresistive dynamic pressure transducers (±0.05% FS) synchronized at 10 kHz sampling rate
• Self-luminous 256×64-dot monochrome LCD display with wide-viewing-angle optics and user-adjustable backlight intensity—compliant with IEC 62368-1 visual ergonomics requirements
• Multi-mode control architecture: local front-panel operation via membrane keypad, plus bidirectional RS232 and USB 2.0 interfaces supporting SCPI command set for integration into LIMS and chromatography data systems (CDS)

Sample Compatibility & Compliance

The AP0012 is validated for use with aqueous, organic, and mixed-phase mobile phases commonly employed in reversed-phase, ion-exchange, size-exclusion, and hydrophilic interaction liquid chromatography (HILIC). Its titanium-wetted path meets USP material classification for Class VI plastics-equivalent inertness and complies with FDA 21 CFR Part 11 requirements when operated with audit-trail-enabled CDS software. All fluidic components conform to ASME BPE-2022 surface finish standards (Ra ≤ 0.4 µm) and are passivated per ASTM A967–22 Method A (nitric acid). The unit carries CE marking under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU.

Software & Data Management

Sanotac provides optional PumpControl Suite v3.2—a Windows-based configuration and diagnostic utility supporting method-driven parameter scripting, real-time flow/pressure trending, event logging (start/stop, pressure fault, seal leak detection), and export to CSV or XML formats. When deployed in regulated environments (e.g., pharmaceutical QC labs), the software supports electronic signatures, role-based access control, and full ALCOA+ compliant audit trails meeting GMP Annex 11 and WHO TRS 996 expectations. Remote firmware updates are digitally signed and verified via SHA-256 hash validation prior to installation.

Applications

• Isocratic and gradient elution in analytical HPLC systems requiring long-term baseline stability (e.g., pharmacopeial assays per USP , EP 2.2.46)
• Method development workflows involving solvent strength screening and column backpressure profiling
• Integration into automated sample preparation platforms (e.g., online SPE-LC-MS coupling)
• High-pressure reaction monitoring systems where precise reagent dosing at ≤42 MPa is required
• Calibration transfer studies between reference and working HPLC systems under ISO/IEC 17025-accredited laboratories

FAQ

What is the maximum allowable operating pressure for the AP0012 with the titanium pump head?
The AP0012 is rated for continuous operation up to 42 MPa (6,090 psi) when equipped with the standard titanium pump head and titanium check valves. Exceeding this limit voids warranty and may compromise seal integrity.

Does the pump support gradient mixing?
No—the AP0012 is a single-channel solvent delivery unit. Gradient functionality requires external low-dead-volume proportioning valves or integration with a dedicated quaternary or binary gradient module.

Can the AP0012 be used with aggressive solvents such as trifluoroacetic acid (TFA) or concentrated sodium hydroxide?
Yes—titanium wetted materials provide outstanding resistance to TFA, HF, and NaOH solutions up to 1 mol/L at ambient temperature; however, prolonged exposure to >0.5 mol/L NaOH above 40°C is not recommended without additional thermal derating.

Is the flow accuracy verified at multiple points across the range?
Yes—factory calibration includes verification at five defined flow points (0.1, 1.0, 5.0, 8.0, and 9.999 mL/min) using NIST-traceable microgravimetric methodology per ISO 8466-1:2021 Annex B.

What safety certifications does the AP0012 hold?
The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment, carries CE marking, and meets RoHS 2011/65/EU and REACH SVHC compliance thresholds for restricted substances.
