The Zeiss Celldiscoverer 7 is a fully integrated and motorized high-end inverted widefield and point scanning confocal fluorescence imaging system ideal for automated live-cell imaging in multi-well plates and Petri dishes. It offers a fully integrated incubation system with temperature and CO2 control and Definite Focus.3 for hardware focus control. The ZEN software can automatically calibrate the system and adapt it to your sample by recognizing different sample carriers, determining their bottom thickness and material and adjusting the objectives correction ring to compensate for spherical aberrations. You can use Petri dishes, chamber slides, multi-well plates, plastic or glass, thin or thick vessel bottoms, low-skirt or high-skirt plates. When using the 50x water immersion objective, automated immersion supply and removal is available for time lapse experiments over several days or extensive scanning processes on multi-well plates. In widefield mode, the fluorescence excitation unit combines seven LEDs – from deep blue to far-red - for high-speed multi-channel imaging and its sensitive cooled Axiocam 712 camera allows you to capture weak fluorescent signals and minimize photobleaching/photodamage in light sensitive samples. In confocal mode, the LSM 900 with Airyscan 2 allows for 3D imaging with increased resolution (120 nm laterally and 350 nm axially in SR mode, at 488 nm) and photomanipulation for FRAP, FRET and related techniques. It can also be used in Multiplex Mode, which enables parallel excitation and detection in 2Y mode (speed improvement of 2x maintaining Airyscan sensitivity).

1. Users can book at maximum 8 hours per week
2. This usage restriction does not apply for weekends and for working days before 9:00 and after 21:00
3. Exceptions to these rules require approval from José Rino.

The system should be always on, you only need to:

• Activate the CD7 by pressing the “Standby” button (to the left of the touch panel)

• Turn on the computer
• Log into Windows with your Agendo credentials
• Start ZEN
• Open the Main valve of the CO2 tank (if needed) - do not change the pressure settings!

If there is another user for this microscope in the next hour:

• Exit the ZEN software, leave the lasers on (if used)
• Log off the computer

Else:

• Close the main valve of the CO2 tank (if used)
• Turn off the lasers on ZEN
• Exit the ZEN software
• Shutdown the computer
• Press the “Standby” button (to the left of the touch panel).

If the system is completely off, please follow this procedure:

• Turn on the MAIN SWITCH (bottom right of the CD7)

• Activate the CD7 by pressing the “Standby” button (to the left of the touch panel)
• Turn on the computer
• Log into Windows with your Agendo credentials
• Start the ZEN software
• Open the Main valve of the CO2 tank (if needed) - do not change the pressure settings!

Please only shutdown the system if instructed to do so by the Bioimaging Unit.

• Close the main valve of the CO2 tank (if used)
• Turn off the lasers on ZEN
• Exit the ZEN software
• Shutdown the computer
• Press the “Standby” button (to the left of the touch panel)
• Turn off the MAIN SWITCH (bottom right of the CD7)
