AOE UV-1600PC Ultraviolet-Visible Spectrophotometer

Overview

The AOE UV-1600PC Ultraviolet-Visible Spectrophotometer is a precision optical instrument engineered for quantitative and qualitative analysis across research laboratories, quality control environments, and educational institutions. Based on the fundamental principle of Beer–Lambert law absorption spectroscopy, it measures the intensity of light transmitted through or reflected from a sample as a function of wavelength in the ultraviolet (190–400 nm), visible (400–700 nm), and near-infrared (700–1100 nm) spectral regions. Its pseudo-double-beam architecture—comprising a high-efficiency 1200-line/mm holographic grating and real-time reference beam monitoring—ensures stable baseline performance and minimizes drift caused by source intensity fluctuations or detector thermal variation. This design delivers high photometric reproducibility (<±0.002 A over 2 h) and supports routine compliance with ASTM E275, ISO 6223, and USP guidelines for spectrophotometric method validation.

Key Features

• Precision optical system featuring a 1200 lines/mm holographic grating and motorized auto-wavelength scanning mechanism with ±0.4 nm accuracy and ≤0.2 nm repeatability
• True-color 480 × 272 TFT LCD display (65,536 colors) providing intuitive graphical interface for spectrum visualization, kinetic plot rendering, and multi-curve overlay
• Onboard data storage capacity for up to 240 calibration curves, each supporting 240 absorbance/transmittance measurements—no PC dependency for basic operation
• Dual USB 2.0 ports enabling simultaneous connection to USB flash drives (for direct data export in CSV or TXT format) and PCL-compatible printers (A4 paper support)
• Firmware upgrade capability via USB flash drive using official AOE-signed update packages; version control and traceability maintained via unique instrument serial number registration
• Compliance-certified hardware and software stack validated against ISO 9001:2015 (Quality Management), CE Directive 2014/30/EU (EMC), RoHS 2011/65/EU (hazardous substances), and CMC (China Metrology Certification)

Sample Compatibility & Compliance

The UV-1600PC accommodates standard 10 mm pathlength quartz, glass, or plastic cuvettes (including matched pairs for ratio-based measurements). It supports liquid, solution-phase samples in transmission mode and is compatible with optional accessories such as cell changers, temperature-controlled holders (−5 °C to 100 °C), and integrating spheres for diffuse reflectance analysis. All firmware and embedded Basic software are registered under the People’s Republic of China National Copyright Administration (Certificate No. 2021SRXXXXXX), ensuring legal protection against unauthorized replication and alignment with intellectual property requirements in regulated procurement contexts. The instrument meets essential performance criteria referenced in GLP-compliant laboratories and satisfies pre-validation prerequisites for GMP-aligned QC workflows per FDA 21 CFR Part 11 when paired with compliant third-party LIMS integration.

Software & Data Management

The embedded Basic software provides native A/T/C/E operational modes (Absorbance, Transmittance, Concentration, Energy), fixed-wavelength scanning, time-scan kinetics, and wavelength-scan quantitation. Raw spectral data and metadata—including date/time stamps, operator ID fields, and instrument serial number—are automatically logged into internal memory. Exported files retain timestamped headers and adhere to ASCII-delimited formats compatible with Excel, OriginLab, and MATLAB import protocols. While the host unit operates autonomously, optional PC-based AOE SpectraLink software (v3.2+) extends functionality to multi-point calibration curve fitting (linear, quadratic, cubic), limit-of-detection calculation per ICH Q2(R2), and audit-trail generation for electronic record retention.

Applications

This spectrophotometer serves critical analytical functions across diverse sectors: determination of nucleic acid and protein concentration (e.g., A₂₆₀/A₂₈₀ ratios), enzyme kinetics assays (NADH/NADPH monitoring at 340 nm), pharmaceutical dissolution testing (USP ), water quality analysis (nitrate, phosphate, COD), dye concentration profiling in textile QA, and pigment characterization in coatings R&D. Its 4 nm spectral bandwidth ensures adequate resolution for most routine applications while maintaining sufficient throughput for high-volume screening environments.

FAQ

Does the UV-1600PC support GLP-compliant data integrity requirements?
Yes—when used with optional SpectraLink software and configured with user access controls, electronic signatures, and audit-trail logging, it fulfills core ALCOA+ principles for raw data preservation.
Can the instrument be integrated into a laboratory network?
It does not feature built-in Ethernet or Wi-Fi; however, USB-to-Ethernet adapters or dedicated PC gateways enable indirect LAN connectivity for centralized data aggregation.
What is the recommended maintenance interval for wavelength calibration verification?
We recommend quarterly verification using NIST-traceable holmium oxide or didymium filters, documented per internal SOPs aligned with ISO/IEC 17025 Clause 6.4.
Is the photometric accuracy verified across the full 190–1100 nm range?
Factory calibration includes verification at key wavelengths (e.g., 200 nm, 360 nm, 546.07 nm, 800 nm); users may perform additional verification using certified reference materials.
Are replacement cuvette holders or fiber-optic probes available as accessories?
Yes—AOE offers OEM-compatible 10 mm, 50 mm, and micro-volume holders, plus SMA-905 fiber-optic coupling kits for remote sampling configurations.
