Gold Nanohelices are chiral nanoscale markers especially suited for Electron-Tomography (ET) / Cryo-ET (CET) / 3D-EM. The Nanohelices are mounted ready to use on a TEM grid.

Gold Nanohelices are chiral nanoscale markers especially suited for Electron-Tomography (ET) / Cryo-ET (CET) / 3D-EM. The Nanohelices are delivered in buffer solution. The sample size is 30µl which is enough for the preparation of more than 10 TEM grids.

The England Finder is a glass microscope slide 75mm x 26mm (3x1") with a uniquely indexed grid pattern that allows individual areas of interest to be referenced.

With GATTA‑AFM nanorulers, now adequate test samples are finally available. The GATTA-AFM nanorulers represent accurate and highly parallelized structures and are therefore perfectly suited to optimize and test the resolution of atomic force microscopes.

Lovins Micro-Slide Field Finder helps you to index points of interest on a microscope slide the same way you find them on a road map.

The normal specimens are evaporated films on a 3.05mm grid of aluminum or thallous chloride. The very small crystalline size yields ring patterns suitable for calibration of camera lenght.

This test specimen is most useful to determine the rotation between a diffraction patter and the selected area image.

A holey carbon film is shadowed with gold and graphitized carbon particles are deposited on a 3.05mm grid. These particles viewed over the holes may be used for assessment of factors limiting the microscope performance.
