Thermo Fisher Evolution™ Pro UV-Vis Spectrophotometer (Domestically Manufactured in Shanghai)

Overview

The Thermo Fisher Evolution™ Pro UV-Vis Spectrophotometer (Domestically Manufactured in Shanghai) is a high-performance, double-beam spectrophotometer engineered for precision absorbance, transmittance, and reflectance measurements across the ultraviolet (190 nm) to visible (1100 nm) spectral range. Built on Thermo Fisher’s proven optical architecture—featuring a high-stability xenon flash lamp, holographic grating monochromator, and low-noise silicon photodiode detector—the instrument delivers exceptional photometric accuracy (< ±0.002 A at 0.5 A), wavelength accuracy (±0.5 nm), and baseline stability (< 0.0004 A/h). Its large sample compartment accommodates diverse accessories—including fiber-optic probes, integrating spheres, temperature-controlled cuvette holders, and reflection stages—enabling method flexibility without hardware reconfiguration. Designed for regulatory laboratory environments, the system supports routine QC testing, pharmaceutical assay development, raw material verification, and stability-indicating methods per ICH Q2(R2) guidelines.

Key Features

• Double-beam optical design with real-time reference beam correction for enhanced photometric reproducibility and drift compensation
• Xenon flash lamp source providing full-spectrum acquisition in under 1 second—eliminating warm-up time and lamp aging effects
• Intelligent accessory recognition via RFID-enabled smart mounts: automatic configuration loading for autosamplers, cell changers, and syringe-based injectors
• Large-volume sample compartment (≥ 200 mm W × 150 mm D × 120 mm H) accommodating custom fixtures, flow cells, and multi-position holders
• Integrated slit-width selection (1–4 nm) for optimized resolution/sensitivity trade-offs in complex matrices
• Compliance-ready firmware architecture supporting audit trail, electronic signatures, and user role-based access control (per FDA 21 CFR Part 11 requirements)

Sample Compatibility & Compliance

The Evolution™ Pro platform supports a broad range of sample formats: standard 10-mm pathlength quartz or UV-grade plastic cuvettes, microvolume stands (0.5–2 µL), fiber-optic probes for in-situ monitoring, and diffuse reflectance accessories for solid or powder analysis. All configurations maintain traceable alignment and calibrated photometric response. For regulated environments, optional compliance packages include USP/EP-certified reference filters (NIST-traceable), documented IQ/OQ protocols, and Validator software for Insight Pro with full 21 CFR Part 11 validation documentation (US Letter or A4 international format). The system meets ISO/IEC 17025 calibration requirements when operated with certified standards and validated procedures. Routine performance verification follows ASTM E275 and USP specifications.

Software & Data Management

INSIGHT Pro software—supplied with all Evolution™ Pro systems—provides intuitive method building, kinetic and scanning workflows, multi-component quantitation, and customizable reporting templates. The software includes embedded security features: encrypted data storage, time-stamped audit trails, session locking, and configurable user permissions (Administrator, Analyst, Reviewer). Raw spectral data is stored in vendor-neutral .spc format; export options include CSV, PDF, and XML for LIMS integration. Optional modules support GLP/GMP-compliant data archiving, electronic batch record generation, and automated report distribution via SMTP or network share. All software updates undergo formal change control and are accompanied by version-specific validation support documents.

Applications

• Pharmaceutical quality control: assay of active pharmaceutical ingredients (APIs), excipient identification, dissolution testing, and cleaning validation
• Environmental analysis: nitrate/nitrite, phosphate, COD, and heavy metal speciation using colorimetric protocols
• Life sciences: nucleic acid quantification (A260/A280 ratios), protein concentration (Bradford/Lowry), enzyme kinetics (NADH/NADPH monitoring)
• Materials science: thin-film thickness determination, bandgap estimation of semiconductors, and pigment dispersion analysis
• Food & beverage: color measurement (CIE L*a*b*), antioxidant capacity (FRAP/DPPH), and adulterant screening

FAQ

Is the Evolution™ Pro UV-Vis spectrophotometer manufactured in the USA?

No—this specific configuration is domestically manufactured in Thermo Fisher’s Shanghai facility under strict global quality management system (QMS) oversight, maintaining equivalency to U.S.-assembled units per ISO 9001:2015 and ISO 13485:2016 standards.
Can the instrument be validated for GMP compliance?

Yes—validated operation is supported through Thermo Fisher’s Validator for Insight Pro software, prequalified IQ/OQ protocols, and NIST-traceable certification kits aligned with USP , EU Annex 11, and FDA guidance on computerized systems.
Are accessories such as the autosampler or fiber probe sold separately?

Yes—all accessories—including the AutoSampler 80, Cell Changer 12, Syringe Injector, and Reflectance Accessory Kit—are available as standalone items with individual part numbers and calibration certificates.
Does the system support remote monitoring or network deployment?

Yes—INSIGHT Pro supports client-server mode over local area networks, enabling centralized method deployment, shared instrument scheduling, and secure remote diagnostics via Thermo Fisher’s Connect platform.
What maintenance intervals are recommended for optimal performance?

Routine verification (wavelength accuracy, photometric linearity, stray light) is recommended every 3 months; full optical alignment and lamp replacement follow manufacturer-specified usage thresholds (typically ≥ 1×10⁹ flashes for xenon lamp).
