MODEL 2040

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

• Fully jeweled mechanism for ultra-precise
planar specimen rotation• Optimized tilt in pole-piece gaps as small
as 5 mm
PLASMA CLEANING
Fischione recommends that you clean thespecimen and specimen holder with its
Model 1020 Plasma Cleaner or Model
1070 NanoClean before insertion intothe TEM.
During collection of tomographic data,
the electron beam will be on the samearea 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.

• Ideal for room temperature electron
tomography• Maximizes tomographic data obtainedfrom the specimen• Extended field of view
• FlexiClamp provides an easy, secure meansof specimen retention

Touch protection

The FlexiClamp is a spring-type, annular ringwhich securely clamps the specimen into thespecimen cup. It maximizes specimen visibility,
even at high-tilt angles. A dedicated tool
facilitates the use of the FlexiClamp.

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

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.
