Hydra Bio – Focused Ion Beam Scanning Electron Microscope (FIB-SEM)

Volume EM for cryo and resin-embedded samples

The Thermo Scientific Hydra Bio Plasma-FIB explores tissues to proteins through volume electron microscopy both at cryogenic and room temperatures and cellular cryo-tomography. Great results start with sample preparation, so choose from four ion species (argon, nitrogen, oxygen, and xenon) that are compatible with all commonly used sample-embedding media and preparation protocols like high-pressure tissue freezing or critical point drying to achieve the ultimate image. Hydra Bio Plasma-FIB addresses multiple workflows including high-resolution serial PFIB imaging, large area serial PFIB imaging, array tomography, correlative light and electron microscopy, and high-throughput lamella preparation for cryo-tomography.

With a state-of-the-art inductively coupled plasma (ICP) focused ion beam and four ion species, the Thermo Scientific Hydra Bio Plasma-FIB helps you find the right ion beam for all your samples.  The Hydra Bio PFIB SEM explores tissues to proteins through volume electron microscopy both at cryogenic and room temperatures and cellular cryo-tomography. The four ion species (argon, nitrogen, oxygen, and xenon) are compatible with all commonly used sample-embedding media and protocols like high-pressure tissue freezing. With its advanced software suite, with the Hydra Bio PFIB you can gather consistent, high-quality, gallium-free data from multiple workflows such as high-resolution serial PFIB imaging, millimeter-scale analysis with Spin Mill Bio Method, array tomography, correlative light and electron microscopy and lamellae cryo-lift-out.

3D imaging at cryogenic temperatures

The Hydra Bio PFIB Cryo Package includes a fully integrated 360° rotation cryo-stage to maintain sample temperature below –170°C and a cryo-sample loading system to ensure that samples remain at cryo temperatures during transfer in and out of the instrument. With the excellent contrast of the Hydra Bio SEM column, uncover sub-cellular details on high pressure frozen and plunge frozen samples. No staining is required. Cryo-fixation avoids the artifacts that are usually associated with classic sample preparation steps with excellent contrast and minimal charging artifacts.

Multiple ion options for optimized PFIB results

The Hydra Bio Plasma-FIB features a unique multiple ion species PFIB column with four ion species (Xe, Ar, O, N) with a patented, automated, and fast switching capability (<10 minutes).  For example, O+ ion-plasma provides superior data acquisition efficiency and image quality for samples embedded in either epoxy- or acrylic-based resins. Unlike Ga-based FIBs, curtain-free surfaces are easily generated for a wide range of materials such as LR-White, HM20, EPON and Quetol resins.

Spin Mill Bio Method for millimeter-scale planar milling and imaging

The unique Thermo Scientific Spin Mill Bio Method on the Hydra Bio Plasma-FIB provides large-area planar milling up to 1 mm in diameter, with a geometry like microtome-based serial block face imaging but at a slice thickness as small as 5 nm. Uncover and visualize large sample areas with Spin Mill Bio Method, then focus in on your regions of interest. It is also ideal to prepare clean and smooth surfaces. The Spin Mill Bio Method is fully automated and easy to set up using guided software. Multiple areas for image acquisition within one experiment can be selected. Each area of interest can be imaged at different imaging settings based on the specificity of the experiment.  Sparse features can easily be identified, and statistically relevant 3D data can be collected from multiple areas.

Cryo-lift-out of cryo-tomography lamellae

The Easylift Cryo Lift-Out System supports “on the grid” and bulk high pressure frozen (HPF) specimen techniques to help confirm region of interest in final lamella.  Fluorescently labeled regions of interested are carefully localized using the iFLM Correlative System, and then extracted and thinned before transferring for tomographic data collection in a cryo-TEM.

Integrated light microscope for correlative imaging

The integrated iFLM Correlative System combines fluorescence and electron imaging with ion milling and guided lamella production and supports correlative (CLEM) workflows. Identify, target, and confirm regions of interest without the hassle of transferring between instruments.
