CLSM - Leica Stellaris 5 upright (Irchel)

Stellaris

The Leica STELLARIS 5 is an automated upright confocal laser scanning microscope allowing simultaneous aquisition of 4 fluorescent channels as well as a transmission bright field channel. The newest TauSense technology gives instant access to lifetime-based information, delivering additional insights to your experiments.This system is ideal for fixed samples.

Location

Remarks

This microscope acquires images with improved axial resolution compared with more coventional widefield microscopes.The newest TauSense technology gives instant access to lifetime-based information, delivering additional insights to your experiments. In addition to the multicolor images in fixed samples the microscope can acquire large tile scans fully automated thanks to the LAS X Navigator.
