Spinning Disc Confocal

Spinning Disc Confocal Microscope

Application

The UltraVIEW VoX (Perkin Elmer) spinning disc confocal (SDC)
microscope combines high rates of acquisition with minimal
photobleaching and is ideally suited for live imaging of rapid
cellular processes.  This inverted microscope is equipped with an
auto focus system, a motorized XY stage and a Piezo Z stage for
4D imaging. The UltraVIEW VoX also includes a PhotoKinesis Unit
for Fluorescence Recovery After Photobleaching (FRAP) and
photoswitching experiments.  Image acquisition, visualization and
quantification is powered by the Volocity software (Improvision).
