Abstract: The main goal of exploring outer space is to collect samples of extraterrestrial objects and return samples to Earth. Our country is going to launch the Chang'e-5 Lunar Probe Task to collect lunar samples and bring them back to Earth for sample analysis. Unsealing the vacuum lunar sample container and protecting the sample with high-purity nitrogen at the same time become problems urgently. This paper introduces one kind of equipment for unsealing and processing the vacuum lunar sample container in Chang'e-5 Lunar Probe Task. This equipment is divided into four parts: transfer chamber, operating chamber, unsealing chamber and purification unit, which can unseal samples with a vacuum of 10-3Pa and keep lunar samples in an environment protected by high-purity nitrogen with a water concentration less than 30ppm and an oxygen concentration less than 20ppm.
