FAQs

1. What are the available work modes in this Single Beam UV-Visible Spectrophotometer?

Single Beam UV-Visible Spectrophotometer offers multiple working modes to suit different analytical needs. The available modes include T( Transmittance mode) measures the percentage of light transmitted through a sample. The (A) Absorbance mode determines how much light is absorbed by the sample at a specific wavelength. Concentration mode (C ) allows users to calculate sample concentration based on the standard curve, and Energy mode (E) measures the energy of light passing through the sample.

2. 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.

3. 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. The automatic wavelength setting ensures accurate and precise positioning without manual adjustments, minimizing human error.

4. 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.

5. What standard accessories come with this Double Beam UV-Visible Spectrophotometer?

Single Beam UV-Visible Spectrophotometer includes four 10 mm glass cuvettes, two 10 mm quartz (UV) cuvettes, PC software, 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), as quartz is transparent to UV light, making it ideal for nucleic acid, protein, and other UV-based analyses. Power cord for electrical connection to operate the spectrophotometer.
