FAQs

1. What are the different scanning speeds of this Single Beam UV-Visible Spectrophotometer?

Single Beam UV-Visible Spectrophotometer features adjustable scanning speeds to optimize performance based on the type of analysis. Users can select from high, medium, or low scanning speeds with a maximum speed of 3000 nm/min. The faster scanning allows quick spectrum acquisition, and slower scanning speeds provide high resolution and more accurate data. This feature optimizes performance, enhancing both efficiency and analytical accuracy.

2. What standard accessories come with this Single Beam UV-Visible Spectrophotometer?

Single Beam UV-Visible Spectrophotometer includes four 10 mm glass cuvettes, two 10 mm quartz (UV) cuvettes, and a power cord. Glass cuvettes are suitable for measurement in the visible range (400 to 700), typically used for colorimetric and general spectrophotometric analysis. The Quartz (UV) cuvette is designed for UV measurements (below 400 nm).

3. Why does this Single Beam UV-Visible Spectrophotometer use two light sources?

Single Beam UV-Vis spectrophotometer is equipped with two light sources, a deuterium lamp and a tungsten lamp, to effectively cover the entire wavelength range of 190 to 1100 nm. The deuterium lamp provides stable and continuous light in the ultraviolet (UV) region, typically from 190 to around 350 nm. The tungsten lamp, on the other hand, emits light in the visible to near-infrared range (approximately 350 to 1100 nm). The spectrophotometer uses both and automatically switches between them to ensure accurate and seamless measurements across the full spectrum.

4. What are the features of this Single Beam UV-Visible Spectrophotometer?

Single Beam UV-Visible Spectrophotometer supports automatic wavelength setting, enhancing efficiency and ensuring accurate and precise positioning without manual adjustments, minimizing human error. Fast scanning allows for quick spectral data acquisition across a wide wavelength range, saving time in routine and research applications.

5. Does this Single Beam UV-Vis Spectrophotometer store test data and working curves?

Yes. Single beam UV-Vis Spectrophotometer offers internal storage, allowing users to save 2000 data and 97 calibration curves for future reference. It supports data transfer, users can easily export their results. This feature enhances workflow efficiency, ensuring data integrity and accessibility for further evaluation, reporting, and record-keeping.
