The Vario 2300 is a Split Beam Scanning UV-Vis Spectrophotometer with
functionalities and capabilities that are normally not offered with a conventional single beam spectrophotometer.
The instrument has a wavelength range of 190-1100 nm and comes with a programmable 5-turret sample compartment. The 240 X 128 backlit graphic LCD along with the soft-touch keyboard offer a versatile and friendly interface for operations.
For enhanced data management capabilities, the Vario 2300, can be used in conjunction with the SpectrumTM - WindowsTM based 32-bit software.
An intelligent library by way of Soft Banks - DataBank, InfoBank and MethodBank simplify routine operations and are a part of the Spectrum software. The diversity and features of these banks establish a new platform for systematic, convenient and correct analysis.
