We offer cryogenic and heating products for a wide range of microscopy applications. Cooling experiments in the vacuum chamber of an SEM provide diverse insight into physical (or biological) processes. We also offer peltier heating-cooling modules (223 K – 373K), liquid nitrogen cryostats (80K), liquid helium cryostats (5K) and the control electronics PID-control, if desired with interface.
For high temperature tests different heating systems are available.Firtsly there are standard versions with open heating surface (variants in 300°C, 500°C and 800°C) as well as with closable heating chamber and optional gas inlet and outlet (variants in 300°C, 500°C, 800°C, 1050°C and 1500°C).
Especially when materials are processed or commissioned at temperatures other than ambient, it is not sufficient to measure mechanical properties only at room temperature. In order to understand the mechanical behavior of materials at elevated temperatures or in harsh environments, we have developed upgrade options for the sample heating specifically designed for the SEM and TEM series PicoIndenter instruments.
Peltier elements can be used both for cooling and – when the direction of current is reversed – for heating.
“The route becomes the destination”, says a well-known saying. When developing our transfer module, the aim was to find an optimal solution for safe transport between the SEM and the glove box. Samples that have been prepared for examination and must not be exposed to any further contact with the environment reach their destination protected. Suitable for almost all SEM.
Working at cryogenic temperatures is more challenging than working at room temperature. The sample is more susceptible to many factors. Therefore, it is important to minimize or eliminate all environmental influences used in conjunction with the microscope, especially possible vibration, air conditioning, and stray electromagnetic fields.
