Product type
A UV Visible Spectrophotometer is an analytical instrument used to measure the intensity of light at different wavelengths in the ultraviolet and visible spectrum. It typically consists of a light source, a sample holder, a monochromator, and a detector. The device works by passing light through a sample and measuring the amount of light absorbed or transmitted, which can provide quantitative and qualitative information about the sample's composition. These instruments are widely used in laboratories for various applications, including chemical analysis, quality control, and research.
| Wavelength range | 190 nm to 1100 nm |
| Light source | Deuterium lamp for UV and Tungsten lamp for visible |
| Detector type | Photodiode or photomultiplier tube |
| Spectral bandwidth | 1 nm to 5 nm |
| Accuracy | ±0.5% to ±1% |
| Data output | USB, RS-232, or Ethernet |
When selecting a UV Visible Spectrophotometer, consider the wavelength range and spectral bandwidth that best suits your application. It's important to specify the required accuracy and detector type based on the sensitivity needed for your measurements. Additionally, inquire about data output options for compatibility with your existing systems. Certifications for quality and compliance may also be relevant depending on your industry standards.
