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-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.
Labtron’s Single Beam UV-Visible Spectrophotometer is designed to support a range of analytical tasks through its multiple working modes. These include Transmittance Mode (T), which measures the percentage of light that passes through a sample, and Absorbance Mode (A), which determines how much light is absorbed by the sample at a specific wavelength. The instrument also features a Concentration Mode (C) that calculates sample concentration based on a standard calibration curve, and an Energy Mode (E) that measures the energy of light transmitted through the sample.
Our spectrophotometer features socket-type deuterium and tungsten lamps that can be easily replaced without the need for optical alignment or recalibration. This design ensures stable and consistent UV-Visible light output, delivering accurate and reliable measurements. Additionally, it reduces operational downtime, enhancing overall efficiency and ease of maintenance.
Labtron’s Double Beam UV-Visible Spectrophotometer is equipped with both deuterium and tungsten lamps, providing notable benefits for accurate and comprehensive spectroscopic analysis. The deuterium lamp delivers a stable light source within the ultraviolet range (190–400 nm), while the tungsten lamp covers the visible to near-infrared spectrum (320–1100 nm). Together, these lamps offer a broad spectral range of 190 to 1100 nm, enabling seamless transitions between UV and visible light measurements for a wide variety of analytical applications.
Labtron’s Single Beam UV-Visible Spectrophotometer includes four 10 mm glass cuvettes, two 10 mm quartz (UV) cuvettes, 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.
