Overview
The Sunny Hengping UV2600 is a high-performance, proportional-monitoring double-beam ultraviolet-visible (UV-Vis) spectrophotometer engineered for precision quantitative and qualitative analysis in academic research laboratories, quality control environments, and routine pharmaceutical and biochemical testing. Its optical architecture employs a split-beam configuration with real-time reference monitoring—where both sample and reference beams are simultaneously measured via a single detector using time-shared modulation—ensuring exceptional baseline stability and compensation for source intensity drift, lamp aging, and environmental fluctuations. The instrument covers a broad spectral range from 190 nm to 1100 nm, enabling full characterization of organic chromophores, transition metal complexes, nucleic acids, proteins, nanoparticles, and dye-based formulations. With a fixed spectral bandwidth of 1.8 nm, the UV2600 delivers optimal resolution for routine absorbance measurements while maintaining high photometric accuracy (±0.3% T) and low stray light (≤0.05% T at 220 nm and 360 nm), critical for reliable high-concentration or low-transmittance assays.
Key Features
- Proportional-monitoring double-beam optics with real-time reference correction for enhanced long-term stability and reduced baseline drift (≤0.001 A/h at 500 nm).
- 6-inch high-resolution monochrome LCD (320 × 240 pixels) supporting direct on-instrument spectral visualization, zoom, smoothing, and peak/valley detection without external software.
- Motorized wavelength drive with automatic zeroing and calibration routines—enabling reproducible wavelength positioning (repeatability ≤0.2 nm) and accuracy within ±0.3 nm across the full 190–1100 nm range.
- Integrated 8-position automated sample changer—accommodating up to seven samples plus one reference position—significantly increasing throughput for multi-sample quantitation workflows.
- Automatic cuvette error compensation algorithm that corrects for pathlength and refractive index variations between matched and unmatched quartz or glass cells—improving concentration accuracy at low absorbance (<0.1 A).
- Tool-free deuterium lamp replacement via flange-mount design; no optical realignment required after lamp exchange, minimizing downtime and service dependency.
- USB 2.0 interface compliant with USB Mass Storage Class (MSC) and CDC ACM protocols—enabling direct firmware updates, data export, and seamless integration with UV-Solution workstation software.
Sample Compatibility & Compliance
The UV2600 supports standard 10-mm rectangular cuvettes (quartz, fused silica, or optical-grade glass), as well as microvolume adapters and optional fiber-optic probes for non-standard geometries. It meets core performance criteria aligned with ISO 9001–certified manufacturing practices and conforms to essential verification parameters outlined in ASTM E275–22 (Standard Practices for Description and Measurement of Performance of UV-Vis Spectrophotometers) and USP (Spectrophotometry and Light-Scattering). While not pre-certified for 21 CFR Part 11, the UV-Solution software package (optional) supports audit-trail-enabled operation, electronic signature templates, and user-access-controlled method locking—facilitating GLP/GMP-aligned deployment when configured with networked file logging and role-based permissions.
Software & Data Management
The optional UV-Solution workstation software extends the UV2600’s analytical capability through a Windows-based graphical interface compliant with Windows 10/11 (64-bit). It provides full support for wavelength scanning (0.1–5 nm step intervals), kinetic time scans (0.2–5.0 s sampling), multi-wavelength analysis (up to eight user-defined wavelengths), and advanced quantitative modeling—including linear, quadratic, cubic, and piecewise calibration curves (up to 15 standard points). Built-in DNA/protein analysis modules apply industry-standard extinction coefficients (e.g., 50 µg/mL for dsDNA at 260 nm; 1.4 mg/mL for BSA at 280 nm) and calculate A260/A280 ratios with configurable thresholds. All data exports are natively compatible with Microsoft Excel (.xlsx), and spectral plots can be saved as BMP or CSV files. Software-generated reports include instrument ID, operator name, date/time stamps, measurement parameters, and raw + processed datasets—supporting traceability requirements in regulated environments.
Applications
The UV2600 is routinely deployed in applications requiring robust, repeatable absorbance-based quantification and spectral profiling. These include: (1) pharmaceutical assay development and QC release testing per USP monographs; (2) enzymatic kinetics and inhibitor screening via time-resolved absorbance monitoring; (3) nucleic acid purity assessment (A260/A280, A260/A230); (4) colorant concentration determination in food, cosmetic, and polymer formulations; (5) catalyst characterization via ligand-field absorption bands; and (6) educational laboratory instruction in analytical chemistry and molecular spectroscopy. Its 1.8 nm bandwidth and low stray light enable accurate analysis of turbid or highly absorbing solutions where single-beam instruments exhibit significant deviation.
FAQ
Is the UV2600 compliant with FDA 21 CFR Part 11?
The base instrument does not include Part 11–compliant features; however, the optional UV-Solution software supports audit trails, electronic signatures, and user authentication when deployed on validated Windows systems with appropriate IT governance controls.
What cuvette materials are supported?
Standard 10-mm pathlength cuvettes made of quartz (190–2500 nm), fused silica (190–3500 nm), or optical glass (340–2500 nm) are fully compatible. UV-grade quartz is required for measurements below 220 nm.
Can the UV2600 perform derivative spectroscopy?
Yes—UV-Solution software enables calculation and display of 1st through 4th order derivative spectra, useful for resolving overlapping peaks and enhancing spectral resolution without hardware modification.
What is the maximum data point capacity for kinetic scans?
The instrument stores up to 10,000 consecutive absorbance or transmittance readings during time-scan mode, with user-selectable intervals from 0.2 to 5.0 seconds.
Does the UV2600 support external printers or network printing?
Direct USB printer connection is not supported; however, exported Excel or BMP files generated via UV-Solution can be printed using standard Windows drivers and network-attached devices.
