FAQs

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

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 instrument.

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

Double Beam UV-Visible Spectrophotometer is equipped with multiple working modes, offering flexibility to meet diverse analytical needs. The Transmittance mode (T) measures the percentage of light that passes through a sample, while the Absorbance mode (A) determines how much light is absorbed by the sample at a specific wavelength. For quantitative analysis, the Concentration mode (C) allows users to calculate the sample concentration based on a standard calibration curve. Additionally, the Energy mode (E) measures the energy of light transmitted through the sample. These comprehensive modes make the spectrophotometer a versatile tool for a wide range of laboratory applications.

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

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.

4. What makes the Double Beam UV-Visible Spectrophotometer user-friendly?

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. drive and host for easy saving, exporting, and sharing data. The massive internal memory reduces manual data recording. It can handle 5 to 100 mm cuvette, allowing flexibility in sample size.

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

spectrophotometer contains Socket-type lamps designed for quick and easy installation or replacement without requiring realignment of the optical system.
