Upright Fluorescence Microscope
Upright Fluorescence Microscope STF31



The SIMSCOP STF31 series fluorescence microscope adopting an excellent quality infinity optical system combined with an LED fluorescence illuminator. The LED fluorescence system is a modular design and does not need an external power box. It can offer blue, green and UV fluorescence excitation groups. The digital screen shows and remember each fluorescence channel light intensity. 


The microscope is good for entry-level fluorescence observation such as immunofluorescence and bio-fluorescence, and bright fields of the biological slide. It is easy to operate, has environmental protection and high safety, and is widely used at schools, university labs, medical centres and scientific research institutes. Users can choose different models based on fluorescence channels.


Furthermore, our XY Microscope Piezo Stages has been designed for use our SIMSCOP Series Microscopes to provide motorized XY positioning of microscopy  samples. Access for SIMTRUM's XY Microscope Stages can be click here.
