EMS MATERIALS SCIENCE & METROLOGY CATALOG 2019–20 EDITION


Building on the success of the PP3010T cryo-SEM/FIB/SEM preparation system, we are pleased to announce three new related products for ambient and cryo temperature transfer.


EQUIPMENT & ACCESSORIES PP3004 QuickLok


 Cryo Transfer Systems


Ambient temperature airlock for SEM, FIB/SEM, beamline and vacuum platforms Quick Overview


The QuickLok provides a rapid way of transferring ambient temperature specimens into SEM, FIB/SEM or other suitable vacuum systems. A key feature of the QuickLok is the ability to vacuum transfer specimens that are sensitive to normal environmental conditions. The transfer device uses a sealed vacuum chamber which can be interfaced to a glove box for inert gas transfer or allow vacuum transfer from a wide range of platforms.


Key Features  Rapid specimen exchange

Mounted onto a suitable vacuum chamber port, the QuickLok consists of a loading chamber body with integrated controls for pumping, venting and transfer. A custom-designed interface flange and connections to the pumping system are included (see Pumping below).


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 specimen types to be handled.


Shaving Cream


Fractured at -140ºC, sublimated at -90ºC for 3 minutes and coated with 5nm of platinum.


Inside the microscope is a stage to accept the specimen shuttle. To aid specimen exchange an interlocked LED chamber light is mounted to the inside of the QuickLok interface.


Use


The specimen is mounted on a suitable holder and the transfer device fitted onto the QuickLok. The airlock and transfer device are then evacuated to a pre-set vacuum and the gate valve opened. The specimen is then guided onto the microscope stage.


For transfer from other vacuum systems, or a glove box, additional interface flanges are available on request.


The QuickLok requires either a rotary pump or oil-free vacuum turbomolecular pumping station (see Options).
