Available Models
Spectrophotometers Zuzi are microprocessor-controlled instruments recommended for laboratory applications, routine use in university exercises and biochemistry and molecular biology laboratories. Spectrophotometers enable qualitative analysis (measurement of absorbance and transmittance), quantitative analysis (measurement of concentration) and also kinetics analysis in the UV-Vis range. The devices provide fast, accurate, repeatable and precise readings for many applications. This is high-end equipment, complete and ready to use.
