Double beam UV-visible spectrophotometer 190nm～1100nm, 2nm

USP-1920 double beam UV-visible spectrophotometer 190nm～1100nm, 2nm

The USP-1920 double-beam UV-visible spectrophotometer adopts rigorous precision double-beam optical system and circuit control system design. The high-quality instrument determines its high standards of accuracy, repeatability, low noise and low stray light indicators, as well as excellent stability and linear range.

Instrument features

• Spectral bandwidth: The instrument spectral bandwidth is 2nm, which ensures excellent spectral resolution and the accuracy required for analysis.
• Ultra-low stray light: The excellent C-T monochromator optical system and advanced electronics system ensure an ultra-low stray light level better than 0.03%, meeting the user's measurement needs for high-absorbance samples.
• High-quality components: The core components are all imported with high-quality parts to ensure the stability, reliability and long life of the instrument. For example, the core light source component is derived from the long-life deuterium lamp of Hamamatsu (HAMAMATSU) in Japan, which guarantees a working life of more than 2000 hours, greatly reducing the maintenance frequency and cost of daily replacement of the light source of the instrument.
• Long-term stability and reliability: The optical dual-beam optical system design, combined with real-time digital proportional feedback signal processing, effectively offsets the signal drift of components such as the light source, ensuring the long-term stability of the instrument baseline.
• High wavelength accuracy: The high-level wavelength scanning mechanical system ensures a wavelength accuracy better than 0.3nm and a wavelength repeatability better than 0.1nm. The instrument uses the built-in spectral characteristic wavelength to automatically detect and correct the wavelength to ensure the long-term stability of the wavelength accuracy.
• Convenient light source replacement: The instrument can replace the light source without removing the outer shell. The light source switching mirror supports the function of automatically finding the best position. The plug-in deuterium lamp tungsten lamp design does not require optical debugging when maintaining and replacing the light source.
• Rich single-machine functions: The single machine is equipped with a 7-inch large-screen color touch LCD screen, which can perform wavelength scanning, time scanning, multi-wavelength analysis, quantitative analysis, etc. It supports method and data file storage. The files can be stored in a USB flash drive, and the computer can view and print the spectrum. Simple and easy to use, flexible and efficient.
• Powerful online software: The instrument is connected to the computer via USB. The online software supports wavelength scanning, time scanning, kinetic testing, quantitative analysis, multi-wavelength analysis, DNA/RNA analysis, instrument calibration, performance verification and other functions. It supports user authority management and operation traceability functions to meet various requirements in different analytical fields such as pharmaceutical companies.
• Rich accessory support: The instrument can be configured with 6-cell or 8-cell automatic sample racks, supports cuvette specifications with an optical path of 1mm to 100mm, and supports spectral testing of various sample forms such as film samples.
