Ceres Ice Defense System

Ceres ice defense system

Reduce ice contamination during cryo electron microscopy (cryo-EM) and cryo electron tomography (cryo-ET) experiments

Three components to reduce ice contamination

Clean Station

Ceres clean station

A purpose-built glovebox for CryoET. Prepare your samples in a low humidity environment without a dry room.

Vitri lock

Ceres Vitri-lock

Transfer samples under vitreous temperatures and high vacuum. This eliminates a major source of crystalline ice contamination during transfer.

Cryo Shutter

Reduce amorphous ice growth within the FIB-SEM by nearly 100%. Users can mill more lamella in one batch.

Many users suffer setbacks in their cryo-EM workflow due to ice contamination and limitations with sample prep. The Ceres Ice Defense System enables better data, every time.


The Ceres is designed to work with your existing Cryo FIB-SEM setup and can be installed on microscopes from Thermo Fisher, FEI, Zeiss, JEOL, and others. The Ceres is also compatible with Aquilos 1, Aquilos 2, Leica, and Quorum cryo workflows.
