MODEL 2030
Ultra-Narrow Gap
Tomography Holder

A holder capable of tilting up to 90° whileproviding a maximized field of view fortransmission electron microscopy (TEM).

• Room temperature tomography inultra‑high resolution microscopes• Extended field of view at high-tilt
angles
PLASMA CLEANING
Fischione recommends that you clean thespecimen and specimen holder with theFischione Model 1020 Plasma Cleaner orModel 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 of
non-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.

• Can tilt up to 90°• Suitable for ultra-narrow gap(< 3 mm) pole-piece geometries• Optimized specimen protection
during insertion into the TEM

Tilts up to 90° in pole-piece gaps lessthan 3 mmclamp provides a uniformly distributed force on
the edge of the specimen.

The ability to collect three-dimensional
information over large ranges of tilt in room
temperature TEM reaches a mechanicallimitation dictated by the combination ofspecimen thickness, size, specimen support, polepiece geometry, aperture, and specimen holder
configuration.

To protect the specimen during holder insertion
into and removal from the TEM goniometer,
the Ultra-Narrow Gap Tomography Holder
features an advanced mechanism that retracts thespecimen cartridge into the body of the specimen
holder.

To obtain high-tilt angles in transmission
electron microscopes, the pole-piece gap
should be large and unrestricted. However, forsome ultra-high resolution materials science
microscopes, this gap can be less than 3 mm.
Hence, high tilt with traditional 3 mm specimen
geometry is not possible.
The Model 2030 Ultra-Narrow Gap Tomography
Holder is capable of tilting up to 90° whileproviding a maximized field of view.

A specimen loading station allows easy
positioning and clamping of the specimen into
the cartridge.

Touch protection
Fischione’s Advanced Tomography Holders arecompatible with the TEM’s touch alarm, which
stops goniometer movement in the event that apole touch occurs. Always be aware of the TEM’s
pole-piece configuration and follow the microscope
manufacturer’s recommendation for operating thegoniometer at high-tilt angles.

Advanced clamping and retracting
mechanisms

Ordering information

The Ultra-Narrow Gap Tomography Holder
accepts a 1.5 mm square or round TEM specimen
or grid into a cartridge, securing it with a single
clamp. The clamp can be fully retracted fromthe specimen receptacle for convenience duringloading and unloading. When engaged, theAll 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.
