Spectrophotometers
Product Details
The WSVT/WSUT 50/60/70 series UV-Visible spectrophotometers are designed for accurate and reliable spectral measurements across the ultraviolet and visible wavelength ranges. Operating based on the Beer-Lambert law, the instrument supports qualitative and quantitative analysis of various substances.
With a stable optical path, high-precision holographic grating, and long-life dual light sources, the system ensures excellent measurement repeatability and long-term reliability. The touch-screen interface further simplifies operation, making it suitable for both routine laboratory testing and advanced research tasks.

Key Features:
Automatic Cell Holder: Supports 6-position automatic switching for cuvettes with 10–50 mm optical path lengths, adapting to diverse analytical requirements.
Reinforced Structure: The enhanced base design improves optical path stability, ensuring accurate and consistent results.
Sealed Monochromator: Prevents dust and humidity interference, extending the durability of optical components.
Long-Life Light Sources: Equipped with deuterium and tungsten lamps (≥2000 hours), with socket-style replacement for easy maintenance.
High-Precision Optical System: 1200 line/mm holographic grating and moisture-resistant coated optical mirrors deliver high measurement accuracy and extended service life.
Data Connectivity: Supports USB storage, printer output, and Bluetooth communication.
Measurement Modes: Photometric, quantitative, kinetic, multi-wavelength, and wavelength scanning (WSVT70).
Optional PC Software: GMP-compliant software with multi-user login management and audit trail capabilities.
Typical Applications:
Chemical Analysis: Determination of reagent concentration and reaction monitoring.
Pharmaceutical Quality Control: Active ingredient content measurement and product release testing.
Environmental Monitoring: Detection of trace pollutants such as nitrates, phosphates, and heavy metal complexes.
Biological Research: Quantification of nucleic acids, proteins, and enzymatic reaction kinetics.
