Overview
The Shimadzu UV-2602 is a high-performance scanning ultraviolet-visible (UV-Vis) spectrophotometer engineered for precision absorbance, transmittance, and reflectance measurements across the 190–1100 nm spectral range. It operates on the principle of single-beam optical path design with a high-stability tungsten-halogen lamp (for visible/NIR) and a deuterium arc lamp (for UV), enabling continuous wavelength scanning at a fixed spectral bandwidth of 1.8 nm. This configuration ensures reproducible photometric accuracy under routine laboratory conditions while maintaining compatibility with standard quartz and fused-silica cuvettes. Designed for integration into regulated and research-intensive environments, the UV-2602 delivers robust baseline stability—particularly when equipped with the optional semiconductor temperature-controlled sample compartment—making it suitable for time-resolved kinetic studies, low-concentration quantitation, and spectral fingerprinting of biomolecules.
Key Features
- Fixed 1.8 nm spectral bandwidth optimized for resolution–sensitivity balance in routine UV-Vis analysis
- Wavelength scanning range from 190 nm to 1100 nm, covering deep UV through near-infrared regions
- Integrated 8-position automatic sample changer for unattended sequential measurement of up to eight samples
- Optional Peltier-based temperature control module (±0.1 °C stability) for enhanced baseline reproducibility and thermal drift suppression
- RS-232C serial interface compliant with ANSI/TIA/EIA-232-F standards for reliable communication with Windows-based PCs
- Dual AC power supply architecture supporting independent operation of optical system and control electronics to minimize electrical noise interference
- Onboard memory and real-time data logging capability, enabling autonomous operation without continuous PC connection
Sample Compatibility & Compliance
The UV-2602 accommodates standard 10 mm pathlength rectangular cuvettes (quartz, glass, or plastic), as well as micro-volume adapters and solid-sample reflectance accessories. Its optical design meets ISO 9001-aligned manufacturing controls and supports compliance workflows aligned with GLP and GMP environments. While the instrument itself does not carry FDA 21 CFR Part 11 certification out-of-the-box, its software architecture permits audit-trail-enabled data handling when deployed with validated third-party LIMS or ELN platforms. Method validation documentation—including wavelength accuracy verification per NIST SRM 2034 and photometric linearity assessment per ASTM E275—can be performed using standard reference materials.
Software & Data Management
The UV-2602 is operated via Shimadzu’s UVProbe software (v3.x or later), a Windows-native application supporting quantitative analysis (single/multi-point calibration, standard addition), spectral subtraction, derivative spectroscopy, and kinetic time-course profiling. Data export is supported in CSV, ASCII, and JCAMP-DX formats for interoperability with MATLAB, OriginLab, and chemometric tools. The software enables full parameter scripting—including auto-wavelength setting, concentration calculation routines, and pass/fail criteria definition—for repeatable assay execution. All measurement logs include timestamp, operator ID (when configured), instrument serial number, and environmental metadata (lamp hours, ambient temperature if monitored externally).
Applications
This spectrophotometer serves core analytical functions across diverse sectors: nucleic acid (DNA/RNA) quantification and purity assessment (A260/A280, A260/A230); protein concentration determination via Bradford, Lowry, or BCA assays; enzymatic activity monitoring (e.g., NADH oxidation at 340 nm); pesticide residue screening in agricultural commodities; heavy metal speciation in wastewater via complexometric colorimetry; excipient characterization in pharmaceutical formulation development; and spectral validation of dye batches in textile quality assurance. Its broad spectral coverage also supports pigment analysis in food matrices and UV filter efficacy testing in cosmetic R&D.
FAQ
Does the UV-2602 support dual-beam operation?
No—the UV-2602 is a single-beam instrument. Reference measurements are performed sequentially, requiring manual or automated blanking prior to sample analysis.
Can the 8-cell autosampler accommodate non-standard cuvette sizes?
The autosampler is calibrated for 10 × 10 mm square cuvettes; custom adapters for 5 mm or 50 µL microcuvettes require mechanical retrofitting and are not supplied by default.
Is firmware upgrade capability available in the field?
Yes—firmware updates are distributed via Shimadzu’s official support portal and installed using the UVProbe software suite under technician supervision.
What maintenance intervals are recommended for lamp replacement?
Deuterium lamp lifetime is rated at ≥1,000 hours; tungsten-halogen lamp at ≥2,000 hours. Usage tracking is logged internally and accessible via diagnostic mode.
Is UVProbe software compatible with Windows 11 and 64-bit architectures?
UVProbe v3.9 and later fully support Windows 10/11 (64-bit) and require .NET Framework 4.8 or higher.
