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 can allow transfer to and from a range of vacuum platforms.
• Rapid specimen exchange
• Inert gas transfer from glove box
• Vacuum transfer into SEM or FIB/SEM from other vacuum platforms
• Upgrade path to CoolLok
• Three-year warranty
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 transfer to and from other range of vacuum platforms.
Cooling dewar, trolley and controller
The cold stage and cold trap are cooled by a floor-mounted, vacuum isolated 21 litre dewar and heat exchanger assembly which at normal operating temperatures can run for up to 24 hours between fills. The gas lines between the dewar and the SEM interface are vacuum isolated for maximum thermal efficiency.
The cooling dewar is located on a floor-mounted trolley which also houses the temperature and gas control system.
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 a bayonet fitting to a dovetail-profile specimen holder (shuttle). Standard shuttles are included, but optional holders allow a variety of specimen types to be handled.
Inside the SEM there is fitted 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.
Using the QuickLok
The specimen is mounted on a suitable holder and the transfer device fitted onto the vacuum airlock. The airlock and transfer device are then evacuated to a preset vacuum, the gate valve opened and the specimen guided onto the SEM stage.
For transfers from other vacuum systems, or a glove box, additional interface flanges are available on request.
25852 glove box valve/airlock interface
An optional glove box valve/airlock assembly (25852) can be supplied. The airlock is connected to a glove box using a generic NW fitting and for most applications requires a suitable pumping system (13034 rotary pump or 2336 turbo plus diaphragm pump system). Gas connections are included. The outer face of the 25852 is designed to accept the vacuum transfer device.
The QuickLok requires either a rotary pump or oil-free vacuum turbomolecular pumping station.
