Product Features

1. UV1900 seriesDual beam UV visible spectrophotometerThe optical system design and circuit control system design are very rigorous, and the selection and control of components are strictly controlled, with high standards of accuracy, repeatability, low noise and low stray light indicators. The linear range and stability indicators are also excellent. There are two configurations, 1nm and 2nm bandwidth, suitable for different users to choose from. The large screen LCD display has high measurement accuracy and stability, making it a high-quality instrument.

The UV1900 series dual beam UV visible spectrophotometer uses Japan's Hamamatsu environmentally friendly (ozone free) deuterium lamp and Osram long-life tungsten halogen lamp, with a service life of up to 2000 hours. The light output can remain stable until its service life, and replacement is extremely convenient.

The UV1900 series dual beam UV visible spectrophotometer offers two operating modes: host measurement mode or software controlled measurement mode.

4. The built-in SCM technology and qualitative and quantitative analysis software can achieve extended functions such as data acquisition and processing, spectral measurement, kinetic measurement, quantitative analysis, DNA determination, and spectral scanning. The menu drop-down analysis software is easy to operate.

5. The UV1900 series dual beam UV visible spectrophotometer has an open sample chamber and can be equipped with reflective sample holder, solid sample holder, constant temperature water bath, and automatic sampler, which are suitable for different applications.

6. Single machine scanning curves can store 9, and working curves can store 9. There is no limit to the amount of storage in online mode.

analysis software

Comfortable operating experience and rich analysis functions - UVCON series qualitative and quantitative data processing and analysis software

Dynamics measurement can determine the time variation of transmittance or absorbance from 1 second to 10 hours, with recording intervals ranging from 0.1 to 60 seconds, allowing for observation of rapid reactions and changes. In the data processing function, there are peak valley detection and derivative operation.
