MODEL 2045
Motorized Dual-Axis
Tomography Holder

A holder that features an optimal tilt angle range innarrow gap (~ 5 mm) pole-piece geometries, while
maintaining microscope resolution.

• Motorized rotational control for highthroughput applications
PLASMA CLEANING
Fischione recommends that you clean thespecimen and specimen holder with its
Model 1020 Plasma Cleaner or Model
1070 NanoClean before insertion into
the TEM.
During collection of tomographic data,
the electron beam will be on the same
area of the specimen for an extendedtime. As a result, organic contamination
may build up on the specimen. A plasma
cleaning time of 10 seconds to 2 minutes
removes the contamination. Longer
cleaning times can remove contamination
spots caused by previous TEM viewing ofnon-plasma cleaned specimens.
When not in use, the holders should be
stored under vacuum in Fischione Model
9010 Vacuum Storage Containers or theModel 9020 Vacuum Pumping Station.

• Interfaces with the FEI transmission
electron microscope (TEM) control system• Maximizes tomographic data obtained
from the specimen• Allows for remote control of rotation anddual-axis functionality• Extended field of view even at high-tilt
angles• FlexiClamp provides an easy, secure meansof specimen retention

The Model 2045 Motorized Dual-Axis
Tomography Holder is based on the revolutionary
Model 2040 Dual-Axis Tomography Holder. The
Model 2045 is designed for room-temperatureapplications when TEM

pole-piece
The specimen drive isgeometries
motorized and interfaces
with the microscope’scontrol system, which allows full software
integration of both specimen tilt and rotation.
The Dual-Axis Tomography Holder features anoptimal tilt-angle range in narrow gap (~5 mm)
pole piece geometries. A fully jeweled mechanism
provides ultra-precise, in-plane, specimen rotation
while maintaining eucentric height.
The specimen can be automatically rotated from+180° to -180° to initially orient either the gridbars or a specimen feature to the alpha-tilt axis.
After the acquisition of the first tilt series, thespecimen can then be rotated 90° with respect tothe first orientation for the subsequent acquisitionof the second tilt series.
Acquiring a dual-axis tilt series enhances thequality of information contained in the tomogram.

Motorization is essential when conducting conicaltilt tomography, as well as any other highthroughput application.
Automation through the microscope facilitates
dual-axis tomography via remote operation,
which is especially useful for TEMs that arelocated in an enclosed environment.
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.

Touch protection
Fischione’s advanced tomography holders arecompatible with the TEM’s touch-alarm thatstops goniometer movement in the event thata pole touch occurs. Always be aware of theTEM’s pole piece configuration and follow themicroscope manufacturer’s recommendation for
operating the goniometer at high-tilt angles.

Ordering information
All Fischione advanced tomography holders
come with a dedicated loading station for secure
specimen handling, tools to assist in specimen
clamping, and a Fischione Model 9010 Vacuum
Storage Container for storing the holder in aclean, vacuum environment.
