What are the key advantages of deuterium and tungsten lamps used in Double Beam UV-Visible spectrophotometer?

Our Double Beam UV-Visible spectrophotometer uses a combination of deuterium and tungsten lamps. The deuterium lamp Provides UV light from 190 to 400 nm and tungsten covers visible to near-infrared range (400 to 1100 nm). This combination ensures full-spectrum coverage, high accuracy, stability, and long-term durability, making it a powerful tool for precise spectroscopic analysis in pharmaceuticals, environmental testing, and research labs.

What work modes are available in this Double Beam UV-Visible Spectrophotometer?

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.

What is the specialty of Socket-type deuterium and tungsten lamps?

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.

What are the storage specialties of this Double beam UV-Vis Spectrophotometer?

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.

What standard accessories come with this Double Beam UV-Visible Spectrophotometer?

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.
