Abstract
Presented are systems, methods, and devices for provisioning controlled sample support, precision sample immersion, and/or post-cooling sample storage of cryo-electron microscopy (cryo-EM) samples and grids. A puck is presented for manual or automated storage of cryo-EM sample grids after the grids and samples have been cryocooled. The puck carries one or more cryo-EM sample grids and includes a puck top portion and a puck bottom portion, each formed with a cryogenic-temperature compatible material. The bottom portion includes multiple receptacles that each accepts and holds a sample grid. The top portion includes an array of funnels. The puck top and bottom portions are assembled together by inserting the top portion into the bottom portion. When the puck may be immersed in a liquid cryogen, each funnel guides a sample grid released into an upper portion of the funnel downward and into a grid receptacle within a bottom portion of the funnel.
