PP vacuum transfer box

Traditionally, in order to ensure the transfer of samples in vacuum environment, vacuum transfer box is usually used. The vacuum transfer box has good vacuum sealing performance. When operating, first install the vacuum transfer box into the sample chamber, use the sample transfer tool to transfer the sample to the vacuum box, after sealing, remove the vacuum box, then install it to the designated window of the test equipment or analysis equipment, then use the sample injection tool to take out the sample, and then install it to the test equipment or sub equipment On the sample table of the analyzer. This kind of operation is tedious, and the universality of vacuum transfer box is not strong.

[0004] in order to solve the above problems, the prior art, such as Chinese patent cn203849265u, discloses an ultra-high vacuum sample transfer device, which uses a magnetic sample transfer rod to transfer samples inside the vacuum pipeline, so as to ensure that the samples are always in the ultra-high vacuum environment during the transfer process. When the sample is transferred by the equipment, the magnetic sample transfer rod passes through the hand valve, extends to the sample preparation system, grabs the sample through the manipulator at the end of the magnetic sample transfer rod, after grabbing the sample, the magnetic sample transfer rod is withdrawn, and the sample is transferred from the ultra-high vacuum sample preparation system to the sample transfer cavity to release the manipulator, so as to realize the sample transfer.
