USP-1901 Double beam UV-visible spectrophotometer 190nm～1100nm, 1nm
Introduction:
The USP-1900 series 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
With rigorous design of precision double-beam optical system and circuit control system, the instrument has high standards of accuracy, repeatability, low noise and low stray light indicators, as well as excellent stability and linear range.
There are two bandwidth configurations, 1nm and 2nm, suitable for different user choices.
The instrument uses German Heraeus high-quality pre-adjusted deuterium lamps and OSRAM long-life tungsten halogen lamps to facilitate light source replacement.
The large-screen 6-inch 320×240 dot matrix digital LCD display with backlight makes the operation of the instrument easy and intuitive.
The sample chamber is designed with a detachable structure. Users can choose measurement accessories such as reflection sample holders and solid sample holders to meet the analysis and testing needs in different application fields.
The Chinese and English operating software developed under Windows environment provides a rich and unique analysis system, including data collection (single point, multi-point measurement, spectrum scanning, quantitative measurement, time scanning and DNA measurement) and various data processing. Help complete analysis and research in many fields, from routine quality control to environmental protection, biochemistry, medicine and health, materials, etc.
Special measurement accessories (optional): USP-1900 long optical path sample holder, USP-1900 seven-unit cell, USP-1900 four-unit cell, USP-1900 reflection rack, USP-1900 solid sample holder.
Wide range of application fields: scientific research, teaching and research institutions, environmental monitoring, petrochemical industry, health and epidemic prevention, geological survey, water quality analysis, agriculture, forestry, animal husbandry and fishery, manufacturing, etc.
