Varian PrepStar 210 Preparative Liquid Chromatography System

Overview

The Varian PrepStar 210 Preparative Liquid Chromatography System is a robust, field-proven platform engineered for scalable purification across analytical development, semi-preparative isolation, gram-scale synthesis support, and pilot-scale process validation. Based on Varian’s ProStar architecture—originally developed under Agilent Technologies’ stewardship prior to the 2010 acquisition—the PrepStar 210 employs high-pressure dual-syringe or dual-plunger pump technology operating in gradient or isocratic mode, delivering precise solvent delivery across an exceptionally broad flow range (0.001–3200 mL/min). This wide dynamic range enables seamless method translation from analytical HPLC (e.g., 4.6 mm ID columns) to preparative workflows (up to 50 mm ID columns), minimizing re-optimization effort during scale-up. The system operates on the Varian Star™ v6.x software suite, a Windows-based chromatography data system compliant with audit trail requirements under FDA 21 CFR Part 11 when deployed with appropriate IT controls (user authentication, electronic signatures, and change history logging). All units offered are post-refurbishment, functionally verified at SpectraLab Scientific’s ISO 9001-aligned calibration lab, and delivered with full operational documentation including pump linearity reports, detector wavelength accuracy verification (using holmium oxide filter), and baseline noise/stability test logs.

Key Features

• Dual independent high-pressure solvent delivery modules supporting binary or quaternary gradient formation with active backpressure regulation
• Varian 2550 UV-Vis detector featuring dual-wavelength monitoring (190–700 nm), 10-mm flow cell, and <1.5×10⁻⁵ AU RMS baseline noise (254 nm, 1 s response)
• ProStar 420 autosampler with 120-position vial capacity, programmable injection volumes (1–5000 µL), and temperature-controlled sample compartment (4–40 °C)
• Integrated column switching valve (6-port, 2-position) for automated fraction collection, column regeneration, or heart-cutting applications
• Rugged stainless-steel fluidic path rated to 400 bar (5800 psi), compatible with common HPLC solvents including THF, DCM, and high-% aqueous buffers
• Pre-installed Star™ v6.4 software with method editor, sequence manager, real-time chromatogram overlay, and customizable fraction triggering logic

Sample Compatibility & Compliance

The PrepStar 210 accommodates standard stainless-steel or PEEK-lined preparative columns (2–50 mm I.D., up to 250 mm length), as well as custom-packed silica, C18, phenyl-hexyl, or amino phases. It supports both reversed-phase and normal-phase separations, including chiral applications when paired with certified chiral columns (e.g., Chiralpak AD-H, Lux Cellulose-2). System validation documentation includes IQ/OQ protocols aligned with ASTM E2500-13 and ISO/IEC 17025:2017 principles. While not supplied with full GMP validation packages, the architecture meets foundational requirements for regulated environments—including hardware-level event logging, password-protected method editing, and raw data immutability via .cdf file structure. Units are verified to meet USP system suitability criteria for resolution (Rs ≥ 2.0), tailing factor (Tf ≤ 2.0), and %RSD of retention time (<1.0%) under standardized test conditions.

Software & Data Management

Data acquisition and control are managed through Varian Star™ v6.4—a mature, stable chromatography data system built on Microsoft Foundation Classes (MFC) architecture. The software provides full audit trail functionality (user login/logout timestamps, method modification history, integration parameter changes), export to CSV, AIA (.cdf), and XML formats, and direct interfacing with LIMS via ODBC drivers. Raw data files retain native detector analog output, peak table metadata, and complete instrument configuration snapshots. Backup and restore procedures follow NIST SP 800-88 Rev. 1 guidelines for media sanitization. Remote access is supported via secure RDP or VNC sessions when configured behind enterprise firewalls; no cloud-hosted components are included or required.

Applications

• Purification of synthetic intermediates and final APIs in medicinal chemistry labs (mg-to-g scale)
• Isolation of natural product fractions from plant extracts or fermentation broths
• Removal of residual catalysts or protecting groups in peptide synthesis workflows
• Stability-indicating method development for forced degradation studies
• Support of DOE-driven column screening for selectivity optimization
• Training platform for chromatographic theory and method transfer in academic core facilities

FAQ

Is this system compatible with modern Windows OS versions (e.g., Windows 10/11)?

Yes—Star™ v6.4 runs natively on Windows 10 (64-bit) and Windows 11 under compatibility mode; driver signing exemptions may be required for legacy USB-to-serial adapters.
Does the 6-month warranty cover detector lamp replacement?

Yes—warranty includes labor and parts for all OEM-specified consumables installed at time of shipment, including deuterium and tungsten lamps.
Can I integrate third-party fraction collectors or mass detectors?

The system features TTL-trigger outputs and analog voltage inputs compatible with most commercial fraction collectors (e.g., Gilson FC204, Advion IsoTherm) and can synchronize with LC-MS systems via external start/stop signals.
Are original manuals and software installation media provided?

Yes—each unit ships with digitized PDF manuals, licensed Star™ v6.4 installation DVDs, and a USB key containing calibration certificates and test reports.
What maintenance is recommended prior to first use?

We recommend replacing pump seals, purge valve filters, and injector rotor seals; these kits are available from Agilent (P/N 5063-6591, 5063-6592) and are included in our optional startup service package.
