AGS-PHG05W06T-ET-K75E2-BE-Q3A AIGIS 5-Position, 6-Channel pH Valve Manifold

Overview

The AGS-PHG05W06T-ET-K75E2-BE-Q3A is a precision-engineered 5-position, 6-channel pH valve manifold designed for integration into automated protein purification systems. It functions as a programmable fluid routing module that enables sequential or selective delivery of up to six distinct buffer or sample streams to a single output path—typically interfaced with a chromatography column, inline pH sensor, or conductivity cell. The device operates on electro-mechanical actuation principles, utilizing high-reproducibility rotary positioning (with angular indexing at 0°, 90°, 112.5°, 225°, and 270°) to ensure repeatable port alignment across thousands of cycles. Its architecture supports both continuous-flow and stop-flow operational modes, making it suitable for gradient elution, pH step gradients, and multi-step wash/elution protocols in FPLC and AKTA-compatible workflows. Constructed with chemically resistant materials—including PEEK, ETFE, and stainless steel wetted components—the manifold maintains integrity under typical protein purification conditions (pH 2–12, ≤1 MPa pressure, ambient to 40 °C).

Key Features

• 5 discrete rotational positions with precise angular indexing (0°, 90°, 112.5°, 225°, 270°) for deterministic channel selection
• 6 independent fluidic channels—each with dedicated inlet tubing ports and unified outlet manifold connection
• Integrated electromagnetic stepper motor drive with position feedback for closed-loop repeatability (±0.1° typical angular accuracy)
• Chemically inert fluid path compliant with USP Class VI and ISO 10993-5 requirements for biopharmaceutical use
• Modular mounting interface compatible with standard 19″ rack panels and OEM purification system chassis
• RS-485 serial communication protocol (Modbus RTU) for seamless integration with PLCs, CDS software, or third-party control platforms
• IP54-rated housing for protection against dust and incidental liquid splashes in laboratory environments

Sample Compatibility & Compliance

The valve manifold is validated for use with aqueous buffers commonly employed in protein purification—including sodium acetate, Tris-HCl, phosphate, and citrate systems—as well as low-concentration chaotropic agents (e.g., ≤1 M urea, ≤0.5 M guanidine HCl). It is not intended for organic solvent exposure (e.g., acetonitrile, isopropanol) or high-salt crystallization buffers (>2 M ammonium sulfate). All wetted surfaces meet FDA-compliant material certifications and are compatible with cleaning-in-place (CIP) procedures using 0.1–1.0 M NaOH. The device conforms to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards. While not certified for GMP manufacturing environments out-of-the-box, its design supports audit-ready documentation packages—including FAT/SAT reports, material traceability records, and calibration logs—for clients operating under GLP or cGMP frameworks.

Software & Data Management

The AGS-PHG05W06T-ET-K75E2-BE-Q3A communicates via ASCII-based Modbus RTU commands over RS-485, enabling native integration with commercial chromatography data systems (CDS) such as UNICORN, Chromeleon, and OpenLab CDS. Configuration parameters—including default home position, dwell time per port, and error timeout thresholds—are stored in non-volatile memory and persist through power cycling. Optional firmware updates support enhanced diagnostics, including real-time valve position verification and stall detection during actuation. When deployed in regulated environments, the device supports electronic record generation when paired with 21 CFR Part 11–compliant software layers—ensuring secure user authentication, audit trails for configuration changes, and tamper-evident event logging.

Applications

• Automated buffer selection in ÄKTA-style FPLC systems for ion exchange, affinity, and size-exclusion chromatography
• pH gradient generation in cation/anion exchange purification of monoclonal antibodies and recombinant enzymes
• Multi-step equilibration and regeneration of HisTrap or Protein A columns
• In-line pH monitoring loops where discrete buffer injection precedes measurement at an upstream sensor
• Parallel sample loading in multi-column chromatography (MCC) or periodic counter-current chromatography (PCC) configurations
• OEM integration into benchtop protein purification platforms requiring compact, reliable fluid switching

FAQ

Is this valve manifold compatible with ÄKTA systems?
Yes—it supports standard 1/16″ OD PEEK tubing connections and RS-485 Modbus RTU communication, enabling direct integration with GE Cytiva ÄKTA systems via optional protocol adapters.
What is the maximum operating pressure?
The manifold is rated for continuous operation up to 1.0 MPa (10 bar) at 25 °C; pressure rating decreases linearly to 0.7 MPa at 40 °C.
Can it be sterilized using autoclaving?
No—autoclaving is not recommended due to thermal limitations of internal electronics and elastomeric seals; steam-in-place (SIP) at ≤121 °C is also unsupported.
Does it include position feedback for validation purposes?
Yes—integrated optical encoder provides real-time rotational position reporting, supporting IQ/OQ documentation for regulated labs.
Are replacement parts available separately?
Yes—individual rotor assemblies, sealing cartridges, and control boards are available as spare parts with full traceability documentation.
