Model 2040
Dual-Axis Tomography Holder
The Model 2040 Dual-Axis Tomography Holder is for room-temperature applications when TEM tomographic imaging or analysis requires in-plane rotation of the specimen. The Dual-Axis Tomography Holder features an optimal tilt-angle range. The holder features a fully jeweled mechanism for ultra-precise specimen movement, which yields highly repeatable specimen rotation while maintaining eucentric height.
Initially, the specimen can be rotated fully through 360°. Once the specimen is properly oriented, a two-position precision mechanism allows 90° in-plane rotation of the specimen. This feature greatly facilitates the acquisition of a dual-axis tilt series. The holder features a FlexiClamp, a spring-type, annular ring that securely clamps the specimen into the specimen cup. It maximizes specimen visibility, even at high-tilt angles.
Included with the holder are a holder stand, a Model 9010 Vacuum Storage Container, FlexiClamp (pack of 10), and a FlexiClamp tool.
The holder:
- Has a fully jeweled mechanism for ultra-precise planar specimen rotation
- Is optimized tilt in pole-piece gaps as small as 5 mm
- Offers an extended field of view
- Is compatible with the TEM’s touch alarm, which stops goniometer movement in the event that a pole touch occurs
Available for both JEOL and Thermo Fisher Scientific microscopes.

Electron tomography of HIV-1 infection in gut-associated lymphoid tissue
Critical aspects of HIV-1 infection occur in mucosal tissues, particularly in the gut, which contains large numbers of HIV-1 target cells that are depleted early in infection. We used electron tomography (ET) to image HIV-1 in gut-associated lymphoid tissue (GALT) of HIV-1-infected humanized mice, the first 3D...
Reducing the missing wedge: High-resolution dual axis tomography of inorganic materials
Electron tomography is a powerful technique that can probe the three-dimensional (3-D) structure of materials. Recently, this technique has been successfully applied to inorganic materials using Z-contrast imaging in a scanning transmission electron microscope to image nanomaterials in 3D with a resolution of 1 nm...
The transformation of enterovirus replication structures: A 3D study of single and double-membrane compartments
All positive-strand RNA viruses induce membrane structures in their host cells which are thought to serve as suitable microenvironments for viral RNA synthesis. The structures induced by enteroviruses, which are members of the family Picornaviridae, have so far been described as either single- or double-membrane...
