This urine collection and transfer device was part of the hygiene equipment used by one of the astronauts during the Apollo 11 mission in July 1969.
Liquid waste (urine) was collected in the device, worn under their clothing, which they attached to themselves using roll-on cuffs to provide sanitary protection. The urine was then transferred through the rubber transfer tube to a tank, from which the majority of liquid waste was vented into space. A small portion was freeze-dried and stored, for testing upon return to Earth.
NASA transferred this to the Museum in 1970.
