PP3010 cryo-SEM preparation system, turbo pumped, 240V
PP3010 cryo-SEM preparation system, turbo pumped, 240V
The PP3010 is a highly automated, easy to use, column-mounted, gas-cooled cryo preparation system suitable for most makes and models of SEM, FE-SEM and FIB/SEM. The PP3010 includes a number of unique but important features, including: off-column cooling (no boiling liquid nitrogen on the microscope), pumped storage of the cryo transfer device.
Visibility is a key feature throughout the whole system. CCD images from the preparation chamber and the SEM (fitted if space allows) are displayed on the control screen, and a large front window and top viewing ports give unsurpassed visibility of the specimen and chamber interior. The PP3010T includes facilities needed to rapidly freeze and transfer specimens. The aQuilo cryo preparation chamber has tools for cold fracturing and for fully automatic sublimation and specimen coating. Once prepared, the specimen can be transferred onto a high stability SEM cold stage for observation. Extensive cold trapping in the aQuilo cryo preparation chamber and SEM can be set to operate at temperatures down to below -190C, ensuring the whole process occurs in a contamination free, high-vacuum environment.
Glovebox interface and various specimen stubs and shuttles are available separately.
Features:
- High resolution performance on SEM, FE-SEM and FIB/SEMs
- Totally gas cooled, including cryo preparation chamber - no boiling nitrogen on the SEM
- Efficient cooling (down to at least -190°C)
- 24 hours plus run times on one fill of LN2 are typical - allowing unattended overnight operation (at typical operating temperatures)
- Large recipe driven touch-screen interface
- Automated sublimation, coating and system start up
- Superb specimen visibility
- Fully compatible with SEM beam deceleration/stage bias modes up to 5kV
- Off column cooling and pumping systems - minimum mass on the SEM
- On-screen data logging and diagnostics
- Pumped storage of the cryo transfer device
- Prepdek workstation - self contained work area, extra bench space not required
- Cryo workflow options
- Specialist support and extended warranty option
