Cryo FIB | Cryo FIB Milling | Thermo Fisher Scientific - US
When using focused ion beam (FIB) milling under cryogenic conditions, an ion beam is directed onto the surface of the frozen-hydrated sample to precisely remove material. FIB technology can produce thin, electron-transparent cryo-lamellae samples for imaging on a cryo-transmission electron microscope (TEM).

The introduction of cryo-techniques to the focused ion-beam scanning electron microscope (FIB-SEM) has brought new opportunities to study frozen, hydrated samples from the field of Life Sciences. Cryo-techniques have long been employed in electron microscopy.
The Thermo Scientific Aquilos Cryo-FIB is a cryo-dedicated DualBeam system that delivers optimal sample preparation for high-end cryo-TEM tomography.
The Arctis Cryo-PFIB is the first FIB to feature an Autoloader – the proven robotic sample-handling device that revolutionized cryo-electron microscopy by enabling easy and robust transfer of 12 cryogenically frozen grids at a time. Similar to Krios and Glacios Cryo-TEMs, the Arctis Cryo-PFIB uses a CompuStage
Practical approaches for cryo-FIB milling and applications for …
In this chapter, we will describe a typical FIB milling protocol using the Thermo Fisher Scientific (TFS) Aquilos, a dual-beam FIB/SEM platform that includes a cryo-stage/quickloader system. However, many of the general principles should be applicable across instruments.
Cryo-FIB specimen preparation for use in a cartridge-type cryo-TEM
A typical cryo-FIB preparation protocol includes four steps: (1) Vitreously freezing the sample; (2) transferring the sample onto the coldstage in the FIB-SEM instrument; (3) FIB-milling the sample; (4) cryotransferring the sample out of the FIB-SEM and into the TEM.
