Introduction to Ultramicrotomy

When studying samples, to visualize their fine structure with nanometer scale resolution, most often electron microscopy is used. There are 2 types: scanning electron microscopy (SEM) which images the…

Array Tomography for SEM 3D Reconstruction

Array tomography (AT) is a 3D image reconstruction technique for high resolution, quantitative analysis of biological structures. For optimal results, ultrathin and ordered sections are an absolute…

Brief Introduction to Specimen Trimming

Before ultrathin sectioning a sample with an ultramicrotome it has to be pre-prepared. For this pre-preparation, special attention must be paid to the sample size (size of the section), location of…
