PP3004 QuickLok cryo-SEM ambient temperature airlock
PP3004 QuickLok cryo-SEM ambient temperature airlock
P3004 QuickLok - ambient temperature airlock for SEM, FIB-SEM, beam-line and vacuum products.
This is not just a sample loading system, but more importantly it allows transfer under vacuum or in inert gas. One of the main applications is the transfer of oxygen-sensitive samples, such as lithium battery and solar cell materials, from a glove box environment to an SEM or FIB/SEM. For this purpose we now have an optional 25852 glove box transfer interface.
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 from a wide range of vacuum platforms.

System components
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 different specimen types to be handled.
Inside the SEM 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.
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 pre-set 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.
Pumping
The QuickLok requires either a rotary pump or oil-free vacuum turbo pumping station (see Options).
