Cryo-SEM Preparation System by Quorum Technologies

The PP3000T 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 PP3000T has all the facilities needed to rapidly freeze and transfer specimens. The cryo preparation chamber is turbomolecular pumped and includes tools for cold fracturing, controlled sublimation and specimen coating. The specimen can then be transferred 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. Key features of the PP3000T:

• High resolution performance
• Large ‘recipe’ driven touch screen user interface
• Easy to use - extensive automation, on-screen help, videos etc
• Column-mounted preparation chamber - essential for frost-free transfer and ease of use
• Cold stage temperature down to -190°C, plus comprehensive cold trapping
• Turbo pumping system mounted off-column - less mass on the SEM
• Unsurpassed specimen visibility - large front window, top viewing ports, multiple LED chamber lighting
• Cameras in the preparation chamber and SEM - cumbersome binocular not needed
• Preparation chamber cooling - eight-hour hold time with a single fill of liquid nitrogen
• Independent gas-cooling of the SEM cold stage and cold trap - temperature range down to -192°C (not possible with conduction cooling)
• Off-column cooling of SEM stage and cold trap - 24 hour hold time
• Actively cooled fracturing and manipulation tools - micrometer knife and probe
• Twin liquid nitrogen slushing and specimen handling system - ideal for handling pre-frozen specimens
