Features

The use of photomultiplier tube as a detector offers exceptional sensitivity.
Powerful functions like Photometric measurement, Quantitative measurement, Kinetics, Spectrum scan, DNA\Protein test, multi-wavelength test, etc
In-house massive memory is capable of saving up to 1024M for test data & working curves.
Supports USB storage. The USB port can be used for data transfer, which is easily exported to Excel for further processing, analysis and storage.
Socket type deuterium and tungsten lamp can make lamps switching without optics debugging and easy to be replaced.
Large sample chamber can accommodate 5-100mm cuvettes of all kinds.
Extensive accessories are optional, such as auto 8-cell holder, film holder, peltier/sipper system, 21 CFR compliant software, built-in printer, etc.
