Research using Nikon C1si confocal system:
The Nikon C1Si confocal microscope was purchased in Apr., 2008. Three research groups including myself share the system. Our research includes enzymatic assay, pickering emulsion, interactions between colloidal particles, gene delivery, and etc.
Opinion on Nikon products:
The microscope has been functioning reliably since the purchase. The solid state lasers provide stable light source. No major problems occurred so far, and for small problems, usually they were fixed either by ourselves or by the CTS supporting staff in a matter of a few days.
It also helps that the optical parts, especially the lenses, can be shared with other Nikon microscopes in our department.
Comments on CTS:
"The sales representatives from CTS are generally professional, and willing to help in time. The support has been consistently satisfactory." - Prof. Bo ZHENG.
