Model 2045

Motorized Dual-Axis Tomography Holder

A holder that features an optimal tilt angle range in narrow gap (~ 5 mm) pole-piece geometries, while maintaining microscope resolution. Interfaces with Thermo Fisher Scientific transmission electron microscopes.

Motorized Dual-Axis Tomography Holder

The Model 2045 Motorized Dual-Axis Tomography Holder is based on the Model 2040 Dual-Axis Tomography Holder. The holder is designed for room-temperature applications when TEM tomographic imaging or analysis requires software-controlled, automated, in-plane rotation of the specimen. The specimen drive is motorized and interfaces with the microscope’s control system, which allows full software integration of both specimen tilt and rotation.

The Dual-Axis Tomography Holder features an optimal tilt-angle range in narrow gap (~5 mm) pole piece geometries. A mechanism provides ultra-precise, in-plane, specimen rotation while maintaining eucentric height.

The specimen can be rotated in one direction to initially orient either the grid bars or a specimen feature to the alpha-tilt axis. After the acquisition of the first tilt series, the specimen can then be rotated 90° in the same direction with respect to the first orientation for the subsequent acquisition of the second tilt series.

Acquiring a dual-axis tilt series enhances the quality of information contained in the tomogram. Motorization is essential when conducting conical tilt tomography, as well as any other high-throughput application.

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, 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
  • 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 Thermo Fisher Scientific microscopes.
