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 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 incorporates both deuterium and tungsten lamps, offering significant advantages for accurate and versatile spectroscopic analysis. The deuterium lamp ensures a stable light source for the ultraviolet region (190–400 nm), while the tungsten lamp efficiently covers the visible to near-infrared range (320–1100 nm). Together, they provide an extensive spectral range from 190 to 1100 nm, allowing seamless measurement across both UV and visible light regions. This broad coverage enhances the instrument's capability to support a wide variety of analytical applications.
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 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.
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.
