Overview
The SUNNY HENGPING UV2000 Ultraviolet-Visible Spectrophotometer is a precision single-beam optical instrument engineered for routine and research-grade quantitative and qualitative analysis in chemistry, biochemistry, pharmaceutical quality control, and environmental testing laboratories. It operates on the fundamental principle of Beer–Lambert law-based absorbance measurement, utilizing a Czerny–Turner (C-T) monochromator equipped with a 1200-line/mm holographic grating to deliver high wavelength fidelity across the ultraviolet, visible, and near-infrared spectral regions. Designed for robustness and operational consistency, the UV2000 integrates a dual-lamp source system—comprising a deuterium lamp for UV emission (190–350 nm) and a tungsten-halogen lamp for visible/NIR output (350–1100 nm)—with automatic lamp switching at user-defined crossover wavelengths. Its 2 nm spectral bandwidth ensures adequate resolution for most standard applications including concentration determination, purity assessment, and kinetic monitoring, while maintaining signal-to-noise performance suitable for low-absorbance measurements.
Key Features
- 4.3-inch full-color TFT resistive touchscreen (480 × 272 resolution) enabling intuitive navigation, method setup, and real-time data visualization without external peripherals.
- High-speed wavelength scanning with motorized grating drive, supporting rapid positioning (<1 s between adjacent 0.1 nm steps) and repeatable spectral acquisition.
- Automated zero-absorbance (0 Abs) and 100% transmittance (100% T) calibration routines executed directly from the instrument interface or UV-Solution software.
- Modular lamp architecture: flanged socket-mount deuterium lamp design permits tool-free replacement; eliminates post-replacement optical alignment procedures, reducing downtime and technician dependency.
- Standard USB 2.0 port for direct connection to Windows-based PCs; supports plug-and-play data transfer and remote instrument control.
- Expandable optical path via optional accessories—including variable-pathlength cuvette holders, fiber-optic probes, and solid-sample reflectance modules—to accommodate diverse sample formats and measurement geometries.
Sample Compatibility & Compliance
The UV2000 accommodates standard 10 mm square quartz or glass cuvettes (pathlengths from 1 mm to 100 mm supported via optional holders), as well as microvolume adapters for ≤2 µL samples. It complies with core international standards governing spectrophotometric instrumentation, including ISO 9001:2015 (quality management systems) and ASTM E275–22 (standard practices for describing and measuring performance of UV–Vis spectrophotometers). While the base configuration does not include regulatory-grade audit trail functionality, an optional GMP-compliant firmware module enables full 21 CFR Part 11–aligned audit trail generation—recording user identity, timestamp, parameter changes, data modifications, and method execution history—with tamper-evident digital signatures and secure export to encrypted CSV or PDF reports. This option supports GLP/GMP environments requiring traceability for QC release testing, stability studies, and raw material verification.
Software & Data Management
UV-Solution is a native Windows application (compatible with Windows 10/11, 64-bit) that serves as the central hub for instrument control, data acquisition, and post-processing. It provides six validated operational modes: Photometric Measurement (single-wavelength A/T), Spectrum Scan (wavelength-resolved A/T/E), Kinetic Scan (time-resolved A/T at fixed λ), Quantitative Analysis (linear/nonlinear calibration curves up to third-order polynomial or custom equations), DNA/Protein Analysis (preconfigured protocols for A260/A280 ratio, extinction coefficient-based concentration derivation), and Multi-Wavelength Analysis (simultaneous A/T readouts at up to 10 user-defined λ points). All acquired datasets are stored in structured binary format with embedded metadata (instrument ID, date/time, operator, method name, calibration status). Export options include Excel (.xlsx), comma-separated values (.csv), bitmap images (.bmp), and printable PDF reports adhering to laboratory documentation best practices. Raw spectral files retain full wavelength-intensity pairs at native 0.1 nm resolution for reprocessing.
Applications
The UV2000 delivers reliable performance across a broad spectrum of analytical workflows: quantification of nucleic acids and proteins in molecular biology labs; assay development and validation in pharmaceutical R&D; excipient and active pharmaceutical ingredient (API) identification per USP guidelines; water quality monitoring (e.g., nitrate, phosphate, COD estimation); dye concentration tracking in textile and pigment manufacturing; catalyst characterization via ligand-field absorption bands; and educational use in undergraduate spectroscopy laboratories. Its extended wavelength capability (190–1100 nm) supports specialized applications such as chlorophyll-a quantification (663 nm), carotenoid profiling (450 nm), and semiconductor thin-film transmission analysis.
FAQ
What is the wavelength accuracy specification of the UV2000?
The instrument achieves ±0.5 nm wavelength accuracy across its nominal 200–1000 nm range, verified using NIST-traceable holmium oxide and didymium oxide reference filters.
Can the UV2000 perform kinetic measurements with programmable sampling intervals?
Yes—kinetic mode supports user-defined time intervals from 0.1 s to 600 s per data point, with up to 10,000 time points per run and automatic baseline correction options.
Is UV-Solution software compatible with LIMS integration?
While UV-Solution does not feature native HL7 or ASTM E1384 interfaces, exported .csv and .xlsx files conform to common LIMS ingestion schemas; custom API wrappers can be developed using the provided SDK for enterprise-level connectivity.
Does the UV2000 support compliance with ISO/IEC 17025 requirements for accredited testing laboratories?
When operated with documented calibration procedures, certified reference materials, and the optional audit trail module, the UV2000 meets technical requirements for method validation, uncertainty estimation, and record retention mandated by ISO/IEC 17025:2017 Clause 7.7.
What maintenance is required for long-term wavelength stability?
Annual verification using certified wavelength standards is recommended; no internal optical realignment is needed under normal operating conditions due to the thermally stabilized monochromator housing and rigid mechanical construction.
