EM ICE Versatile High Pressure Freezing platform
High-pressure freezing is essential for detailed analysis of cellular components, as it enables rapid cryo-immobilization of aqueous samples while preserving their ultrastructure. EM ICE combines advanced high-pressure freezing with light and electrical stimulation, making it the ideal platform for groundbreaking discoveries in electron and correlative microscopy.
Preserve samples in their native states
Cryo-fixation is the only way to fix cellular constituents without introducing significant structural alterations.
The EM ICE high pressure freezer uses a unique, alcohol-free freezing principle to allow for a superior cryo-fixation of the specimen enabling better quality results to be obtained:
- No alcohol in the chamber leads to a faster pressure increase and immediate cooling of the specimen
- No alcohol residue on the carrier or the specimen
- One move: fully automated loading to freezing in 1 second
Freeze your sample for a range of applications
High-quality frozen samples are the essential prerequisite for advanced cryo-EM workflows like cryo-electron tomography (Cryo-ET) and on-grid lamella preparation, including waffle freezing.
Sample structure preservation means the EM studies observation reflects the true physiological state of the sample at an unparallel resolution.
High pressure freezing with EM ICE is a starting point for 3D volume EM workflows like Array Tomography and serial block face imaging. After successful vitrification samples undergo freeze substitution to enable detailed electron microscopy studies.
