Double Beam UV-Vis Spectrophotometer LUS-B19 FAQ's
  • Our spectrophotometer equipped with a 7 inch color screen and a window style graphic interface, making operation. The automatic wavelength setting, different workmodes and variable scanning speeds allows for quick setup and flexible operation based on user needs. It has a socket-type deuterium and tungsten lamps enable lamp changes without requiring optics realignment. USB drive and USB host for easy saving, exporting, and sharing data. The massive internal memory reduces manual data recording. It can handle 5 to 100 mm cuvettes of all kinds, allowing flexibility in sample size.

  • Our spectrophotometer contains Socket-type lamps designed for quick and easy installation or replacement without requiring realignment of the optical system. This means users can replace the lamps themselves without needing technical expertise or service support, which minimizes downtime in busy laboratory environments.Additionally, these lamps offer stable light output and long operational life, ensuring consistent and reliable performance over time. Their plug-and-play design enhances instrument uptime, making them ideal for laboratories that require routine and uninterrupted spectrophotometric analysis.

  • Labtron’s Double Beam UV-Visible Spectrophotometer comes equipped with four 10 mm glass cuvettes, two 10 mm quartz (UV) cuvettes, and a power cord. The glass cuvettes are ideal for measurements in the visible light range (400–700 nm), commonly used in colorimetric and general spectrophotometric analyses. The quartz cuvettes, on the other hand, are specifically designed for UV region measurements (below 400 nm), as quartz allows UV light to pass through, making them suitable for UV-based studies. The power cord provides the necessary electrical connection to operate the instrument.

  • Labtron’s 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.

  • Our Double Beam UV-Vis Spectrophotometer comes with 1GB of internal memory, providing ample space to store large volumes of test data and calibration curves for future reference. It also supports USB storage, allowing users to effortlessly export data to Excel for detailed analysis. These storage capabilities streamline data management, enhance workflow efficiency, and ensure data integrity for easy retrieval, reporting, and long-term documentation.
