Cryo-SEM Preparation System - The PP3010T from Quorum Technologies

The PP3010T 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 PP3010T has all the facilities needed to rapidly freeze, process and transfer specimens. The aQuilo cryo preparation chamber is turbomolecular pumped and includes tools for cold fracturing, controlled automatic sublimation and sputter coating. After processing, the specimen is transferred from the cryo preparation chamber onto a highly stable SEM cold stage for observation. Cold trapping in the cryo preparation chamber and SEM chamber ensures the whole process is frost free. Specimen process times are typically between five and ten minutes.

Key features of the PP3010T:

General:

  • High resolution performance on SEM, FE-SEM and FIB/SEMs
  • aQuilo gas cooled cryo preparation chamber
  • Efficient cooling (typically down to at least-190°C)
  • Up to 24 hours run times on one fill of LN2 - allowing unattended overnight operation
  • Large recipe driven touch-screen interface
  • Automated sublimation, coating and system start up
  • Superb specimen visibility (including preparation chamber CCD camera)
  • Fully compatible with SEM beam deceleration/stage bias modes up to 5kV
  • Off column cooling and pumping – minimum mass on the SEM
  • On-screen data logging and diagnostics
  • Vacuum storage of the cryo transfer device
  • Prepdek™ workstation – self contained work area, extra bench space not required
  • Specialist support and three year warranty

aQuilo cryo preparation chamber

  • Subject to microscope geometry, fits onto a single microscope chamber port – compact installation, frees up microscope ports
  • Mounted directly on the microscope - essential for frost-free transfer and ease of use
  • Integrated valves - enhanced vacuum performance
  • Gas cooled cold stage and cold traps – rapid cooling down to -190°C or lower
  • Turbo pumping system located off-column - less mass on the SEM
  • Typical vacuum when cold: 10-6mbar or better – specimen transfer into the SEM always high vacuum to high vacuum
  • Unsurpassed specimen visibility - large front window, top viewing ports and multiple LED chamber lighting
  • Preparation chamber CCD camera for specimen observation - bulky binocular no longer needed
  • Automated high resolution sputter coating using Quorum's market leading "Q" series technology
  • Fracturing/specimen manipulation devices
