The Core Sample Vacuum Container (CSVC) provided a receptacle for a 4 cm diameter drive tube so its sample of subsurface lunar regolith could be returned to Earth without exposure to terrestrial atmosphere or spacecraft cabin gases. The CSVC was a derivative of the Special Environmental Sample Container (SESC), elongated to accommodate the drive tube. The twist-on cap was comprised of a knife edge indium seal. One 4 cm drive tube core sample was sealed in a CSVC on Apollo 16 and one on Apollo 17.
This particular unit was never flown. It was transferred to the Smithsonian from its manufacturer in 1973.
