Hitachi High-Tech Announces a New Tabletop Atmospheric Scanning Electron Microscope, AeroSurf 1500, for observation of wet specimens at atmospheric pressure

TOKYO, Japan, March 7, 2016 – Hitachi High-Technologies Corporation (TSE: 8036, Hitachi High-Tech) has announced the release of the new tabletop atmospheric scanning electron microscope (ASEM), AeroSurf 1500, in the U.S.A. The AeroSurf 1500 accommodates the observation of high-moisture specimens, such as soft materials and biological specimens, in their natural state.

With a conventional SEM, specimens with high-moisture content need to be dehydrated and dried so that they will not deform while under vacuum. Such complicated preprocessing often causes alterations to specimens. A popular approach to observe high-moisture specimens is a cryogenic method; however, cryogenic systems can be costly and not readily accessible.
Hitachi High-Tech, a leading provider of electron microscopes, responded to the diversity of our customers’ requirements and developed the AeroSurf 1500.

The AeroSurf 1500 enables SEM observation of high-moisture specimens at an atmospheric pressure, not under vacuum. The specimen chamber and the SEM column are separated by a membrane which isolates the high-vacuum column from the atmospheric specimen chamber while allowing electron beam irradiation of the specimen. This greatly reduces the need for time-consuming preprocessing of high-moisture specimens. The use of this membrane is optional, allowing both atmospheric and traditional SEM analysis with one instrument.
The AeroSurf 1500 is ideal for observing high-moisture specimens during the drying process.

Hitachi High-Tech introduces the AeroSurf 1500 at the Pittsburgh Conference & Exposition 2016 (Pittcon 2016), held at the Georgia World Congress Center in Atlanta, U.S.A, from Sunday, March 6 through Thursday, March 10, 2016.
