Product Details
SEMPeltier in-situ heating and cooling platform
Applicable to all scanning electron microscopes
Standard cold table (temperature range:-25°C to +50°C）
With the increasing use of low vacuum or variable pressure microscopes, many microscopists now realize the need to control water sublimation in wet samples. By cooling the wet sample, the sublimation of water may slow down or depend on the completely stopped chamber pressure. The saturated vapor pressure of water significantly decreases with increasing temperature.
At room temperature, water will quickly sublime, causing significant changes in the structure of the sample. stay300PaWhen, the sample temperature needs to be lower than-9.5°C, in85PaWhen, the sample temperature needs to be lower than-25°CTo stop sublimation. Therefore, by cooling the sample to-25°CThe sample can be found at85PaInside the chamber, and the sample sublimation is limited. The advantages of this program are obvious. By cooling the sample under low vacuum, the structural changes caused by sublimation can be minimized, and the ability to operate under higher vacuum can provide better signal-to-noise ratio and clearer images. By using environmental scanning electron microscopy, it is possible to image in a gas environment, and the temperature and vacuum degree can be perfectly matched to maintain complete hydration of the sample during the imaging process.
DebenThe cold stage can also be used for high vacuum heating and cooling applications within scanning electron microscopes.
DebenCold table is suitable for all surfactants, ensuring a temperature range of+50°Cto-25°C(In)300PaUnder room pressure, or below a higher vacuum level-30°C.
Enhanced cold table (temperature range:-25°C to +160°C）
The enhanced cold table has the same functions as the standard cold table, but the temperature range is from-25°Creach+160°C.
DebenThis cold stage can also be used for high vacuum heating and cooling applications within scanning electron microscopes.
DebenThis cold bench is suitable for all surfactants, ensuring a temperature range of+50°Cto-25°C(In)300PaUnder room pressure, or below a higher vacuum level-30°C.
Super cold table (temperature range:-50°C to +50°C）
