This set of 12 bulk storage grid boxes includes 2 units of each of the 6 color grid boxes: 2 blue, 2 green, 2 purple, 2 yellow, 2 pink and 2 white. Each grid box comes with a pin lid, for a total of 12 pin lids. 
 
NanoSoft's patented (pending) bulk storage grid box design enables the optimal storage of 12 autogrids, an entire cassette in one grid box. Furthermore, 12 unclipped grids can also be stored comfortably in this grid box, enabling the storage of an entire cassette of samples from vitrification to data collection.
