Transmission Electron Microscope (TEM): JEM-2100 LaB6

RCaH provide a Transmission Electron Microscope (TEM) for research use.

The JEM-2100 electron microscope has been designed for use in fields including materials, nanoelectronics, and biological sciences. 

The JEM-2100 features a high-stability goniometer stage specifically tuned for high tilt tomographic applications. Users may select from a variety of illumination conditions, ranging from full convergent beam to parallel illumination. The incorporation of an objective mini lens means that Lorentz microscopy is a standard feature of this microscope.

The equipment at the research complex provides:

  • In-gap (for delicate samples) Objective Apertures
  • Single Tilt Sample Holder with Quick Exchange Tips plus Tomography tip
  • Double tilt sample holder
  • Cryo specimen holder for imaging frozen unstained samples.

For more information from the manufacturer, including a more detailed product specification, see the product page on the JEOL website.

Advanced software is available for use with the TEM and Gatan Camera digital camera:

  • Gatan TEM Tomography software
  • Gatan AutoTune software
  • Gatan DigitalMontage software
  • Gatan HREM tuning software
  • Gatan Digital Streaming Video software

For more details about this software, please see the Gatan website.

Sample Preparation Equipment for TEM

Ion Mill: Fischione Model 1050

Ion milling is used on physical science specimens to reduce thickness to electron transparency. Inert gas, typically argon, is ionized and then accelerated toward the specimen surface. By means of momentum transfer, the impinging ions sputter material from the specimen at a controlled rate.

The Fischione Model 1050 TEM Mill can be use to for create the thin, electron transparent specimens needed for TEM imaging and analysis.

Fischione Model 200 Dimpling grinder

This is a microprocessor controlled mechanical thinning instrument for TEM specimen preparation and small scale polishing/grinding

  • Grinding rate control
  • Auto-termination
  • Digital read-out for monitoring of specimen thickness
  • x40 Optical microscope
  • Illumination for transmitted and reflected light sample inspection

Fischione Model 170 Ultrasonic Disc Cutter

The Model 170 Ultrasonic Disk Cutter rapidly cuts transmission electron microscopy (TEM) specimens from hard, brittle materials without mechanical or thermal damage. It directly produces disk specimens from materials as thin as 10 microns,

FEI Vitrobot Plunge Freezer

The Vitrobot Mark IV is a fully automated vitrification device for plunge-freezing of aqueous (colloidal) suspensions. It can be used to prepare frozen samples for use on the TEM.

Other Materials Sample Preparation Equipment

The following Struers sample preparation equipment for materials are available:

  • Struers Citovac
  • Struers CitoPress-1 and Mounting units
  • Struers Accutom-5
  • Struers LaboPol-5 grinder/polishers (two)
  • Struers Minitom: Low-speed precision cut-off machine.
