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 features variable scanning speeds, allowing users to select from high, medium or low speed settings based on their specific analytical needs with a maximum scanning speed up to 3000 mm. High speed scanning is ideal for time-Sensitive analysis where rapid data acquisition is essential. Medium scanning provides a balance between analysis time and spectral resolution, making it suitable for general purpose measurements. Low speed scanning, delivers higher resolution and accuracy, flexibility and scanning speedometer ability across a wide range of samples and testing requirements.
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 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.
Labtron’s spectrophotometer contains a USB port (USB drive and USB host) that enables users to export data to external storage devices such as flash drives. This simplifies data sharing between the spectrophotometer and external systems allowing results to be stored and accessed on different computers. The USB host feature also supports direct connections to peripheral devices like printers. The RS232 interface allows direct communication with computers, printers, or other laboratory information systems (LIS).
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 applications like nucleic acid, protein, and other UV-based studies. The power cord provides the necessary electrical connection to operate the spectrophotometer.
