The invention relates to cryogenic technology, namely, to devices for obtaining components of gas mixtures by rectification method, particularly, neon isotopes. is a holder attached to and stored at the back of a cabinet door and when deployed will support an object for viewing from the front of the closed door. In one aspect, the polymer binding material comprises a polymer binder blend comprising first and second polymers, wherein the first polymer has a glass transition temperature higher than the second polymer.
