MODEL 2040 Dual-Axis Tomography Holder

  • Description
  • Specification
  • Accesories
  • Consumables


The Dual-Axis Tomography Holder is for transmission electron microscopy imaging or analysis that requires in situ specimen rotation. Acquiring a dual-axis tilt series enhances the information contained in the tomogram.

The Dual-Axis Tomography Holder features an optimal tilt angle range in narrow gap (~5 mm) pole-piece geometries, while maintaining microscope resolution.

A fully jeweled mechanism provides ultra-precise, in-plane specimen rotation, while maintaining eucentricity.

Key Specifications

  • Fully jeweled mechanism for ultra-precise planar specimen rotation
  • Optimized tilt in pole-piece gaps as small as 5 mm
  • Ideal for room temperature electron tomography
  • Maximizes tomographic data obtained from the specimen
  • Extended field of view

MODEL 130 Specimen Punch

Prepare high-quality disk specimens. A precision ground punch and die plate eliminate specimen stress and distortion. For convenient handling, a spring-loaded return plunger keeps the disk specimen on the die plate surface.

Available with or without a base and in standard sizes of 1.0 mm, 2.3 mm, and 3.0 mm. Other sizes available upon request.

Model 160 Specimen Grinder

For transmission electron microscopy, the quality of the initial disk determines the quality of the final specimen. The Model 160 Specimen Grinder is an accurate and dependable tool for mechanically prethinning specimens. It produces specimens of uniform thickness and parallel sides within minutes. During the grinding process, a graduated scale allows the specimen thickness to be controlled easily and precisely. If further thinning via dimpling is required, the platen containing the specimen is simply ejected from the specimen grinder and installed directly into the Model 200 Dimpling Grinder.
