We also support OEM projects and system integration, providing consistent product design, technical documentation, and long-term supply to ensure smooth integration and reliable operation throughout the project lifecycle.

A double beam UV-Vis spectrophotometer splits the light into two paths—one for the sample and one for the reference—allowing real-time baseline correction. This significantly improves measurement accuracy, stability, and repeatability, especially in long-term or high-precision industrial analysis.
👉 Compared to single-beam systems, it is the preferred choice for pharmaceutical QC, environmental testing, and laboratory spectroscopy applications.
UV-Vis spectrophotometers are widely used for:
Chemical concentration analysis
Water quality and environmental monitoring
Pharmaceutical raw material and finished product testing
Food safety and additive detection
DNA, RNA, and protein quantification
These applications make it essential for industrial quality control and regulatory compliance testing.
When selecting a UV-Vis spectrophotometer, consider:
Measurement accuracy and repeatability
Wavelength range (e.g., 190–1100 nm for full UV-Vis coverage)
Compliance requirements (GLP/GMP)
Data management and software capabilities
Expandability (auto sampler, accessories)
For industrial buyers, a double beam UV-Vis spectrophotometer with stable optics and compliance-ready software offers the best long-term value.
A UV-Vis spectrophotometer measures light absorbance/transmittance at specific wavelengths, while a spectrometer provides broader spectral analysis.
In industrial and laboratory settings, UV-Vis spectrophotometers are preferred for:
Routine quantitative analysis
Quality control workflows
Standardized testing procedures
Yes. UV-Vis spectrophotometers are commonly used for DNA, RNA, and protein concentration measurement, particularly at wavelengths like 260 nm and 280 nm.
They are widely used in:
Biotechnology labs
Pharmaceutical R&D
Academic research institutions
High accuracy and repeatability are critical for biological sample analysis, making double beam systems more reliable.
Key factors include:
Light source stability
