Exact CRYO DualBeam Sectioning and Imaging of vitreous frozen biological specimens.
CRYO DualBeam Sectioning and Imaging.
For the first time collecting representative Scanning Electron Microscope IMAGING DATA from a biological sample preserved in its native state and from a precise location is possible.
Advantage 1 – UNTIL now CRYO SEM Samples have been randomly fractured to reveal internal structures. Cryo DualBeam permits the exact placement of a section through a feature of interest visible by SEM imaging of the frozen sample.
Advantage 2 – samples which contain both biological and solid state elements and the delicate interfaces between them were almost impossible to prepare. Cryo DualBeam cuts through solid state materials with the same ease as frozen biological material, permitting interfaces between them to be directly imaged.

NanoScope offers the innovative new technique for your Life Science samples.
This technique pioneered by NanoScope Engineers offers the benefits of native state CRYO freezing with the exact sectioning of a feature made possible only with a Focused Ion Beam.
All surface damage and heating effects are removed by a sublimation step and subsequent Gold coating of the section face, making High Resolution FEG SEM imaging immediately available.
For a detailed description of the equipment and techniques available, go to the Tools and Techniques page.
