Hot Stage Microscopy

Real-world materials applications often take place under variable environmental conditions, including high temperatures. The behavior of your heated material as it recrystallizes, melts, and deforms can inform critical macro- and microscopic observations, such as how a manufactured part might respond to stress or how feed materials behave during production. As a sample’s response to heat is a dynamic process, it must be paired with dynamic observation for accurate insight. Modern heating stages in electron microscopes allow for in situ experiments for high-resolution observation of heated materials. These demanding experiments are capable of linking sample morphology, environment, and thermodynamics, and can help you control the corresponding behavior of the bulk material.

SEM heating stages

There are many considerations when operating electron microscopes at elevated temperatures, such as the desired temperature range, sample size, and chemical environment. The following table shows what is possible with Thermo Scientific temperature stages.
