Scanning Electron Microscope (SEM): JSM-6610LV

RCaH provide a Scanning Electron Microscope (SEM) for research use.

The JSM-6610LV low vacuum SEM is a high-performance scanning electron microscope for fast characterization and imaging of fine structures on both small and large samples. The JSM-6610LV enables observation of specimens up to 200mm in diameter.

The Low Vacuum mode allows for observation of specimens that cannot be viewed at high vacuum due to excessive water content or because they have a non-conductive surface.

The SEM allows for detailed measurements, including 3D measurement from stereo images. Dual live image display of the secondary electron image and a backscattered composition image allow the user to contrast and compare specific details.

The equipment at the research complex provides:

  • Secondary electron (SE) detectors
  • Low-vacuum secondary electron (LV-SE) detectors
  • Back-scattered electrode (BSE) detectors

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

Sample Preparation Equipment

Sputter Coater/Carbon Coater: Quorum Q150T ES

The Q150T is a compact turbomolecular-pumped coating system suitable for SEM, TEM and many thin film applications. The model at RCaH is both a high resolution sputter coater and a high vacuum carbon coater, with easily changeable deposition heads. The glow discharge attachment is also available.

Gold (Au), Platinum (Pt), Gold/Palladium (Au/Pd) and carbon targets are available for coating. A complete list of available targets can be found on the Quorum site here, but the Research Complex does not offer all of these as standard.

For more details, see the Quorum website.

Critical point dryer: Quorum E3100 Large Chamber Critical Point Dryer

Critical point drying is an established method of dehydrating biological tissue prior to examination in the Scanning Electron Microscope. The water in biological tissue is replaced with a suitable inert fluid (CO2 at the Research Complex) whose critical temperature for a realisable pressure is just above ambient.

The Research Complex also has a sample holder for cover-slips and TEM grids.
