Double Beam UV-Vis Spectrophotometer LUS-B27 FAQ's
  • Labtron’s Double Beam UV-Vis Spectrophotometer contains photomultiplier tube, are extremely sensitive light detectors capable of detecting very low levels of light, which makes them ideal for analyzing samples with low absorbance. In a double beam configuration, the PMT enhances precision by accurately detecting minute differences in light intensity between the sample and reference beams, improving baseline stability and measurement accuracy. Their fast response time allows for real-time monitoring of kinetic reactions, while their low noise characteristics contribute to a higher signal-to-noise ratio, resulting in clearer, more reliable data.

  • Our Double Beam UV-Visible Spectrophotometer can be exported through multiple methods. It comes with a USB port that allows users to save measurement data directly to a flash drive, making it easy to transfer and analyze the data on a computer. It often includes an RS232 serial port, which enables real-time data transfer to a connected PC or printer. This spectrophotometer also has built-in memory, enabling data storage within the instrument itself, which can later be accessed and exported. These options make data management efficient and suitable for further analysis, reporting, or archival purposes.

  • Labtron’s Double Beam UV-Visible spectrophotometer contains deuterium and tungsten lamps, offering significant advantages for comprehensive and precise spectroscopic analysis. The deuterium lamp provides stable light in the ultraviolet range (190–400 nm), while the tungsten lamp covers the visible to near-infrared range (320–1100 nm), together enabling a wide spectral coverage from 190 to 1100 nm. This broad range allows users to perform both UV and visible light measurements seamlessly.

  • Our Double Beam UV-Visible Spectrophotometer features adjustable scanning speeds to optimize performance based on the type of analysis required. 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.

  • Labtron’s Double 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. Power cord for electrical connection to operate the spectrophotometer.
