CRYO-SEM & CRYO-FIB/SEM PREPARATION EDITION III


zzzCryo Transfer Systems (continued) PP3006 CoolLok


Cryo transfer systems for SEM, FIB/SEM, beamline and vacuum platforms Quick Overview


The 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.


Please Note: The PP3006 is not a replacement for the PP3010, which is a full cryo preparation system. The PP3006 does not have a cryo preparation chamber and is designed for materials applications where cold fracturing and sputtering are not required.

z Rapid specimen exchange z Temperature range down to -190°C with stability better than 0.5°C z Off-column cooling with all-day runtime between fills z Independent cooling of cold stage and cold trap z Vacuum or inert gas transfer z Rapid specimen freezing option z 3 year warranty


Components


On-microscope components: airlock, cold stage, cold trap plus cryo transfer device


Vacuum airlock cold gas feedthrough Mounted onto a suitable vacuum chamber port, the CoolLok consists of a loading chamber body with built-in controls for pumping, venting and transfer. A custom- designed interface flange to the vacuum chamber and connections and fittings to the pumping system are included (see Pumping below). The interface has cold


nitrogen gas feeds to and from the microscope cold stage and cold trap.


Specimen holders and transfer device The compact vacuum transfer device has an easy-release bayonet fitting to a dovetail- profile specimen holder (shuttle). Standard shuttles are included, but optional holders allow a range of different specimen types to be handled.


Load lock with vacuum isolated gas cooling lines


Cold stage and cold trap A highly stable, thermally isolated, nitrogen gas-cooled cold stage attaches to the microscope stage. The location and shape of the cold trap is tailored to suit the internal geometry of the microscope. Both cold stage and cold trap are capable of reaching temperatures down to -
