JASCO UV-VIS V-660 Spectrophotometer Introduction

The JASCO UV-VIS V-660 is a high-performance spectrophotometer developed by JASCO Corporation (Japan), widely used for optical analysis in chemistry, biology, pharmaceuticals, and materials science. Combining a precision optical system with intelligent operation software, this instrument supports various measurement modes including transmission, reflection, and absorption, making it suitable for rapid analysis of liquid, solid, and thin-film samples.

Key Features

1. Broad Wavelength Range & High Resolution

   • Covers 187-900 nm (UV to NIR) with deuterium and tungsten lamps ensuring full-spectrum stability
   • Features double-beam design with a silicon photodiode detector delivering high signal-to-noise ratio (S/N >50,000:1) and resolution up to 0.1 nm for trace sample detection

2. Versatile Measurement Modes

   • Supports absorbance (Abs), transmittance (%T), reflectance (Refl.) measurements, with expandability to fluorescence and circular dichroism spectroscopy
   • Built-in wavelength scanning, time scanning, and kinetic analysis functions for reaction monitoring and kinetic studies

3. Intelligent Operation & Data Processing

   • Equipped with Spectra Manager™ software (Windows compatible) for integrated data acquisition, analysis, and reporting compliant with GLP/GMP requirements
   • Optional autosampler available for high-throughput sample analysis

4. Flexible Sample Compatibility

   • Accommodates micro-volume cells (minimum 0.6 μL), temperature-controlled cells, and solid sample holders
   • Optional integrating sphere accessory for diffuse reflectance analysis of powders or highly scattering samples

Typical Applications

• Biochemistry: Protein/nucleic acid quantification (e.g., 280 nm protein absorbance analysis)
• Pharmaceuticals: Drug purity testing and dissolution studies
• Environmental: Trace analysis of water pollutants (nitrates, heavy metals)
• Materials Science: Optical characterization of nanomaterials (absorption edges, band gaps)

Technical Advantages

• Stability: Thermostatically controlled optical system minimizes environmental interference
• Sensitivity: Detection limit as low as 10⁻⁸ g/mL (UV region) for trace analysis
• Compliance: Meets pharmacopeial (USP/EP) and ISO 9001 standards for QC laboratories

Conclusion
With its high precision, versatility, and user-friendly design, the JASCO V-660 serves as an ideal solution for both routine laboratory analysis and advanced research applications, particularly suited for scenarios requiring high reproducibility and automated operation.
