Laevitas 800
Laevitas 800 is a completely new and unique concept, designed for extreme performance with high sensitivity and separation.
Until now, many compounds, such as Chinese herbal mixtures, have been still difficult to be separated. Laevitas 800 is designed especially for complex compounds, unknown mixtures and those which need a fast and higher-resolution analysis coped with our specific columns.
Besides, Laevitas 800 is designed into a fully integrated system, consisting of gradient pump, a robatic and high-precision autosampler, a column oven and optional detectors, including UV-VIS, ECD, LIF, together with the unique concept of all the critical components being built into the column oven to ensure a higher through-put, stability and sensitivity.
The system gives more than a chemistry needs for some analytical data. It gives a whole new concept of easiness, convenience, and jet-like efficiency for the modern chemical, biotechnological and life sciences.
