Tescan Vega 3 Thermionic SEM
About
The Vega 3 is a workhorse thermionic tungsten filament SEM. With the addition of the Low Vacuum Secondary Electron Tescan Detector, this SEM is capable of high resolution secondary electron imaging at both high and low vacuum. The peltier-cooled stage can cool a sample down to -50 ̊C at a rate of 30 ̊C per minute and allows for imaging of wet samples at low vacuum.
An 80 mm² Oxford EDS detector enables rapid mapping capabilities and precise x-ray compositional data and a CL detector allows for imaging of fine details deep within a sample.

Sample Preparation
- Carbon coater. The carbon coater pulses a strong current through graphite rods to coat samples in fine mist of conductive carbon.
- RMC Boeckeler PowerTome PC cryogenic ultramicrotome. The microtome creates nanometer thin sections, ideal for sample analysis with our STEM detector.
- CO2 critical point dryer. The CPD allows for gentle dehydration of a sample, preventing tissue damage from rapid atmospheric evaporation.
