AI Technical Summary

Technical Problem

During sample transfer, how to protect the original microstructure of the sample from damage under special environments (such as freezing, vacuum, neon gas, high temperature, etc.), especially how to provide an effective protective environment during the sample transfer, preparation, processing and analysis stages.

Method used

Design a sample transfer protection chamber, including a transfer cavity and a transfer rod. The transfer cavity is connected to a protective environment providing device. The sample is safely transferred in different environments through a sealing structure and opening and closing device. The transfer rod is used to pass through or enter the transfer cavity when the opening and closing device is opened. The air extraction port and venting port of the protective cavity are adjusted to match the protective environment.

Benefits of technology

It enables the safe transfer and handling of samples in different environments, ensuring that the samples are not damaged during the transfer process. It is suitable for various equipment and environments, including closed vacuum systems, gas-protected environments, and open systems.
