They have silicon photodiode detectors, automatic wavelength adjustments, and tungsten and deuterium lamps. These feature LCD displays and USB ports for data storage and transportation. They provide a variety of measurement methods to satisfy various analytical needs. Our double beam spectrophotometers have exceptional performance and durability, auto calibration, user-friendly interfaces, and enhanced optics for precision.








Our spectrophotometer uses socket-type deuterium and tungsten lamps, which can be replaced without requiring optical alignment or calibration. It ensures stable and reliable UV-Visible light output for accurate measurements. Additionally it minimizes downtime during operation.
Double Beam UV-Vis 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 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.
Our Double beam UV-Vis Spectrophotometer offers 1GB of internal storage,allowing users to save a large amount of test data and calibration curve for future reference. It supports USB storage users can easily export their results into Excel for further analysis, making data handling more efficient. This feature enhances workflow efficiency, ensuring data integrity and accessibility for further evaluation, reporting, and record-keeping.
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 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.
