CLSM - Leica SP8 inverse (Schlieren)

SP8-Schlieren

The Leica SP8 is an automated inverted confocal laser scanning microscope allowing simultaneous acquisition of 4 fluorescent channels and 1 transmitted light channel (BF or DIC). A climate chamber and resonant scanner favor confocal live cell studies.

Location

University Zurich, Schlieren, Room WAD-12-K-105.
