Description:

A conventional transmission electron microscope which is optimized for high contrast imaging at low to moderate magnifications (<100,000X). This instrument is most commonly used to image thin (<200nm) samples of polymers and frozen hydrated solutions (surfactants, colloids, emulsions). This microscope is also used to train users new to TEM.

Equipment:

The JEOL 1210 TEM has a maximum operating voltage of 120 kV. It is capable of imaging in high-magnification (>1,000X) and low magnification and diffraction modes. It has a minimum dose software, free lens control, and some on-line measurement capabilities.

Accessories:

• Gatan video camera for real-time image observation.
• Gatan Multiscan CCD camera (1024 x 1024) for digital image acquisistion.
• Gatan cryotransfer specimen holder.
• Single-tilt, double-tilt, and tilt-rotate ambient temperature specimen holders.

Applications:

• Conventional imaging and diffraction analysis
• Cryo-transfer TEM of frozen hydrated specimens
• Low-dose imaging of delicate specimens

Capabilities:

• Accelerating voltage range 40-120 kV.
• Resolution 0.20 nm lattice, 0.36 nm point.
• Magnification from 50x to 800,000x.
• Graphical user interface with mouse control of most microscope functions.
