Quorum technologies has been the market and technology leader in electron microscopy coating and cryogenic preparation since 2001. The market-leading Q Series of vacuum coating systems and PP3010T cryo preparation systems for SEM and FIB/SEM – both true ground-up redesigns that have truly set the standard within the specimen preparation field.
Quorum’s market-leading PP3010T cryo sem preparation system is the latest in cryo-SEM technology and combines the highest quality results with unparalleled ease of use. The PP3010T is a highly automated, column-mounted, gas-cooled cryo sem preparation and cryo transfer system suitable for most makes and models of W-SEM, FE-SEM and FIB/SEM.
Cryo preparation techniques for cryo SEM and FIB/SEM are essential for the observation of biological, wet or beam sensitive specimens. Using cryo sem electron microscopy removes the need for conventional preparation methods, such as chemical fixation and critical point drying, and allows observation of specimens in their natural hydrated state.
Quorum also pleased to offer the PP3005 SEMCool and PP3006 CoolLok – part cryo preparation systems for low temperature applications where the full specimen processing capabilities of the PP3010T may not be required.
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.
Key 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 (typically down to at least -190ºC)
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
The PP3006 CoolLok offers rapid transfer and cryo temperature observation of specimens for SEM, FIB/SEM, beamline or other vacuum systems. Applications include thermal protection of beam-sensitive specimens and low temperature observation of materials such as plastics, polymers low-K dielectrics and hard-soft mixtures. The system can also be used for inert gas transfer of ambient temperature specimens from a glove box.
Key features
Rapid specimen exchange
Temperature range down to -190°C with stability better than 0.5°C
Off-column cooling with all-day runtime between fills
The SEMCool is based on the PP3006 CoolLok but without the PP3004 QuickLok components. It is designed for cryogenic applications where airlock exchange of specimens into the microscope is not required.
Key features
Temperature range down to -190°C with stability better than 0.5°C
Off-column cooling with all-day runtime between fills
