Zeiss LSM780 Confocal Microscope
The Zeiss LSM 780 is an upright confocal with 32 channel ultra sensitive GaAsP detectors that allow visualization of weak fluorescent signals with lower photobleaching and phototoxicity. In addition, the system can be used for spectral imaging, photon counting and fluorescence correlation spectroscopy (FCS). The added Multiphoton laser is a 3 Watt Chameleon Vision II with a range of 680 - 1080 nm. The NDD detection system can be used for imaging multiphoton florescence or detection of second harmonic generation (SHG) in the forward and reverse directions. Furthermore, the new OSCiscan function allows faster acquisition of high quality data and better time resolution.
Laser Lines: 405 nm, 458 nm, 488 nm, 514 nm, 561 nm, 633 nm

The SkyScan 1276 is a high performance, stand-alone, fast, desk-top in vivo micro-CT with continuously variable magnification for scanning small laboratory animals (mice, rats, hamster, etc.) and biological samples.
It features a combination of high resolution, big image size, round/spiral scanning, reconstruction, and low dose imaging.
The image field of view (up to 80 mm wide and more than 300 mm long) allows full body mouse and rat scanning.
The variable magnification allows scanning bone and tissue samples with high spatial resolution down to a 2.8 µm pixel size.
Variable X-Ray energy combined with a range of filters ensures optimal image quality for diverse research applications from lung tissue to bone with metal implants.
The SkyScan 1276 in vivo micro-CT administers low radiation dose to the animals allowing multiple scans in longitudinal preclinical studies without the risk of unwanted radiation-induced side effects.
The system can perform scanning with continuous gantry rotation and in step-and-shoot mode with the fastest scanning cycle 3.9 sec.
Attached, dedicated gas anesthesia unit for intravital imaging.
