Minimize ice growth during lamellae preparation

Did you know that the typical 50 nm/hour ice growth rate accepted by cryo-FIB providers would mean your 150 nm lamella could become several times thicker at the end of a sample preparation session?

CERES Ice Shield is liquid nitrogen-cooled and provides cryo-pumping to lower the partial pressure of water in the chamber and sample vicinity, thus reducing amorphous ice growth to a minimum level. With the patented, innovative cryo shutter design, your cryo sample is particularly shielded from the contamination originating from the electron column, and therefore preventing condensation on the sample. With the >7-fold decrease in ice contamination rate, you can prepare many more lamellae before the first lamella becomes covered in ice.

This work is supported by the European SME2 grant № 879673.

Read application note

Easy integration for complete protection

The CERES Ice Shield consists of a high precision cryo shutter that inserts between the scanning electron microscopy (SEM) pole piece and the sample. This shields the sample from ice contamination originating from the SEM column while also increasing the local vacuum through cryo-pumping (Tacke et al., 2021). The innovative shutter design comes with a hole that allows FIB milling while the shutter is inserted, fully protecting the sample during lamellae fabrication.
