GoGo Instruments Technology (Shanghai) Co., Ltd. specializes in temperature control technology, offering a range of patented products including probe heating/cooling stages, optical heating/cooling stages, in situ stretching stages, in situ XRD/SEM heating/cooling stages, ultra-high-temperature heating stages, and high/low-temperature test chambers, as well as testing systems for dielectric thermal spectra, electrocaloric effects, charge-discharge testing, and variable-temperature D33 measurements.

A Scanning Electron Microscope (SEM) is a large, precision instrument used for high-resolution micro-area morphological analysis. It offers significant depth of field, high resolution, intuitive imaging, strong stereoscopic effect, a wide magnification range, and allows the sample to be rotated and tilted in three-dimensional space. Additional advantages include the ability to analyze a wide variety of sample types, minimal damage or contamination to the original sample, and the simultaneous acquisition of morphological, structural, compositional, and crystallographic information. Currently, SEMs are widely used for advanced research in life sciences, physics, chemistry, forensics, earth sciences, materials science, and industrial production.

An SEM heating/cooling stage is a device specifically designed for in-situ variable temperature testing of samples within a Scanning Electron Microscope (SEM). As an indispensable equipment in modern materials science research, the importance and practicality of SEM heating/cooling stages have gained widespread recognition.

The GoGo Instruments SEM heating/cooling stage is an SEM accessory that provides in-situ variable temperature testing for samples, mounted directly on the standard SEM sample stage (without requiring internal modifications to the microscope). Temperature control for the sample on the heating/cooling stage is achieved via an external flange device. Its main functions include:

>> In-situ Variable Temperature Testing: The GoGo Instruments heating/cooling stage can be directly installed on the standard sample stage of an SEM (without internal modifications to the microscope) to provide in-situ variable temperature testing. This design enables researchers to observe microstructural changes in samples under high and low-temperature environments, thereby obtaining direct evidence of material phase transition processes.

>> High/Low Temperature Structural Studies: This equipment supports a temperature control range of -190℃ to 200℃, meeting the needs for studying phase transitions and micro-surfaces of various high and low-temperature materials. For example, observing a nickel sample at -50℃ can reveal its structural characteristics under low-temperature conditions.

>> Precise Temperature Control: SEM heating/cooling stage utilizes PID temperature control, achieving temperature stability of ±0.1℃ , and possesses programmable temperature storage and control capabilities. This high-precision temperature control ensures the accuracy and reliability of experimental data.

>> Rapid Heating and Cooling: Through dual cooling technology (electrical heating and liquid nitrogen cooling), the SEM heating/cooling stage enables rapid heating and cooling, with maximum rates up to 60℃/min. This allows researchers to quickly change sample temperature, capturing more transient change information.

>> Seamless Integration with SEMs: This equipment is compatible with Zeiss, Hitachi, and other mainstream SEM brands, and can also be adapted for domestic brands like Guoyi Quantum (SEM3200) and Zhongke Keyi. The installation and disassembly process is simple and does not affect the original functionality of the SEM. This provides convenience for users of different equipment.

>> High-Quality Image Acquisition: Even under relatively large electron beam currents, the SEM heating/cooling stage ensures high-quality image acquisition, aiding researchers in obtaining clearer microstructural images.

>> Diverse Application Scenarios: Beyond basic variable temperature observation, the SEM heating/cooling stage can also be applied in various scenarios such as performance testing of battery electrode materials at different temperatures.

Based on customer requirements, GoGo Instruments customizes SEM heating/cooling stages to adapt to Zeiss Scanning Electron Microscopes (SEM) for in-situ variable temperature testing of samples (enabling observation from different directions, both planar and cross-sectional).
