FAQs

1. What are the key advantages of deuterium and tungsten lamps in the Double Beam UV-Visible Spectrophotometer?

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.

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

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.

3. What is the specialty of the socket-type deuterium and tungsten lamps in the Single Beam UV-Visible Spectrophotometer?

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.

4. What standard accessories come with this Single Beam UV-Visible Spectrophotometer?

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.

5. How can we export data from this Double Beam UV-Visible Spectrophotometer?

spectrophotometer contains a port ( drive and 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 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 ().
