Cost effective and fast service providing high resolution electron microscopy (EM) images, statistical data and accurate measurements combined with expert guidance.

Objective and time efficient analyses

The Vironova EM service team uses the in house developed Vironova Analyzing Software (VAS) designed to analyze transmission electron microscopy (TEM) images of nano-sized particles.
Significant amount of time is saved and the results are consistent and reproducible.
