Such experiments can be carried out using an in situ nanoindenter placed inside the vacuum chamber of an SEM.

Scanning Electron Microscopy (Ernst Ruska, 1986 Nobel Prize) has seen massive growth in both materials and life science over the last few years. On the one hand ease-of-use and slick integration with ancillary techniques has made it the go-to microscope for new material research, whilst new aberration corrected TEM and Cryo-microscopy techniques (Dubochet, Frank, and Henderson, 2017 Nobel Prize) have revolutionised protein characterisation. Virus-research today would probably take ten times as long without this impressive technology.
Allectra为大多数领先的SEM公司提供了电气馈电和其他组件，其中可靠性和鲁棒性是关键的。我们也经常参与最终用户。使用新技术（材料测试人员，纳米管剂，加热器等）进行改造，可以代表延长这些重大投资的研究生活的好方法。
Recently the ELTE research group at the Department of Materials Physics, Eötvös Loránd University, Budapest, Hungary installed a new in situ nanoindenter, using a specially designed Allectra High Vacuum feedthrough plate. The plate was fitted with 5 Sub-D 15 pin feedthroughs, 2 double-sided BNC feedthroughs and a Triaxial feedthrough. By welding the feedthroughs to a single Viton-sealed plate, superior vacuum integrity is assured.
The lead researcher Dr. István Groma said “The research group’s goal is to improve the existing in situ nanomechanical testing methods. Due to the complication of the high time resolution and the low signal to noise ratio it is of utmost importance to use an appropriate data acquisition method. The upgrade of the SEM system attached with the in situ device went ahead smoothly and the technical support provided by Allectra and their Hungarian partners Metlok meant that we were always confident about the signal handling.”
SEM是一个FEI（现为Thermo）量子3D FEG，带有双光束SEM和FIB。
Allectra很高兴讨论您对改装SEM或FIB的进料需求，无论是Thermo，Tescan，Zeiss，Jeol，Hitachi还是其他制造商，我们可以为您的项目提供量身定制的盘子。
