USP-1920 double beam UV-visible spectrophotometer 190nm～1100nm, 2nm
Product Introduction:
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.
