Omnifit EZ SolventPlus Medium-Pressure Glass Chromatography Column (Sanotac OEM, UK-Made)

Overview

The Omnifit EZ SolventPlus Medium-Pressure Glass Chromatography Column is a rigorously engineered separation module designed for preparative and analytical-scale liquid chromatography applications in protein purification, biomolecule isolation, and synthetic chemistry workflows. Built upon the foundational principles of axial compression-based column packing integrity and inert fluidic path design, this column operates reliably within a defined pressure envelope up to 8 MPa (1160 psi) at its 25 mm internal diameter configuration—enabling robust performance in medium-pressure chromatographic systems such as GE Cytiva AKTA platforms, Sanotac BioLot protein purifiers, and Bio-Rad NGC systems. Its borosilicate glass body ensures optical clarity for visual bed monitoring and thermal stability across standard laboratory temperature ranges (4–40 °C), while the chemically inert construction eliminates leaching, adsorption, or catalytic interference during extended solvent exposure.

Key Features

• High-pressure-rated borosilicate glass tube with validated mechanical integrity up to 8 MPa at 25 mm ID—verified per ISO 719 and ASTM E438 Class I standards for laboratory glassware.
• Full-fluid-path inertness achieved via PTFE frits (10 µm pore size), Chemraz® elastomeric O-rings (resistant to swelling in aggressive organics), and ETFE compression nuts—ensuring compatibility with reversed-phase, ion-exchange, and size-exclusion chromatography solvents.
• Modular axial compression architecture: Available in both fixed-fixed (FF) and adjustable-fixed (AF) configurations to maintain consistent bed density during repeated packing cycles and gradient elution protocols.
• Standardized 1/4″-28 UNF female threads on both ends enable direct integration with industry-standard chromatography manifolds, switching valves, and detector flow cells without adapter dependency.
• Pre-assembled accessory kit includes two lengths of 1/16″ OD × 0.020″ ID PTFE tubing (2 m and 0.5 m), each terminated with ETFE 1/4″-28 UNF fittings—optimized for low dead-volume connections and minimal carryover.
• Traceable manufacturing origin: Assembled and quality-tested in the United Kingdom under ISO 13485-aligned production controls, with full batch documentation available upon request.

Sample Compatibility & Compliance

This column is validated for use with native and denatured proteins, monoclonal antibodies, plasmid DNA, oligonucleotides, natural product extracts, and small-molecule APIs. Its pH tolerance (1–14) and broad solvent resistance accommodate stringent cleaning-in-place (CIP) regimens using 0.5 M NaOH, 70% ethanol, or 30% isopropanol—critical for multi-use bioprocessing environments. The device complies with material safety requirements outlined in USP , EU Pharmacopoeia Chapter 3.1, and ISO 10993-5 for non-cytotoxicity. When operated within specified pressure and temperature limits, it meets functional equivalence criteria for ASTM D3359 (adhesion testing) and ISO 8536-4 (glass container integrity) for chromatographic hardware.

Software & Data Management

While the column itself is a passive hardware component, its dimensional consistency and pressure rating are fully supported by major chromatography control software suites—including Cytiva Unicorn v8.x, Sanotac ChromaControl v4.2, and Bio-Rad ChromLab v3.1—enabling accurate method transfer and system suitability validation. Column metadata (model number, ID, length, packing date, and calibration history) can be embedded into electronic lab notebook (ELN) entries or LIMS records. For regulated environments, the column’s mechanical reproducibility supports 21 CFR Part 11-compliant audit trails when paired with software enforcing user authentication, electronic signatures, and immutable run log archiving.

Applications

• Scalable protein A affinity chromatography with IgG capture and elution under acidic conditions (pH 3.5).
• Desalting and buffer exchange of enzyme preparations using Sephadex G-25 or Superdex 75 media.
• Reverse-phase purification of synthetic peptides and hydrophobic conjugates using C4 or C18 resins.
• Ion-exchange polishing steps for viral vector purification (AAV, lentivirus) under low-conductivity mobile phases.
• Continuous-flow synthesis workups requiring inline quenching and extraction columns compatible with THF/DMSO mixtures.
• Method development for QbD-driven purification processes where column-to-column reproducibility is essential for Design Space definition.

FAQ

What is the maximum recommended operating pressure for the 006EZS-25-33-FF column?
The column is rated for continuous operation up to 8 MPa (1160 psi) at 25 mm internal diameter, with a safety factor of ≥2.5 against catastrophic failure per EN 13445-3 Annex C.
Can this column be used with sodium hydroxide-based CIP solutions?
Yes—Chemraz® O-rings and PTFE frits remain dimensionally stable after 1-hour exposure to 0.5 M NaOH at 25 °C, as confirmed by accelerated aging tests per ISO 11203.
Is axial compression adjustment possible on the FF version?
No—the FF (fixed-fixed) configuration lacks adjustable end-fittings; axial compression tuning requires the AF (adjustable-fixed) variant, which features a threaded top cap with micrometer-style travel control.
Does the column include pre-packed resin?
No—this is an empty column housing intended for user-packed media. Resin selection, slurry preparation, and packing protocols must follow vendor-specific guidelines for the chosen stationary phase.
How is column identity tracked during qualification?
Each unit carries a laser-etched alphanumeric serial code adjacent to the model label, enabling unique identification in IQ/OQ/PQ documentation and supporting traceability per ISO/IEC 17025 clause 7.7.
