# What you learn

- How much the CERES Ice Shield reduced the ice growth in multiple cryo-FIB/SEMs 
- How you can create more high-quality lamellae per session and thereby obtain higher resolution structures

## Minimizing Ice Contamination During Lamellae Fabrication using CERES Ice Shield

Ice growth on lamellae is one of the most common problems that limit researchers from acquiring high-resolution 3D structures of cellular samples through cryogenic electron tomography. CERES Ice Shield consists of a cryo-shutter that protects the sample from ice contamination originating from the scanning electron microscopy (SEM) column and increases the local vacuum through cryo-pumping. The shutter design comes with a hole that allows focused ion beam (FIB) milling while the shutter is inserted.
