The first storage box for High Pressure Freezing hats.
The Metal Universal HPF and Grid Box is the first storage box for High Pressure Freezing hats (3mm sized), and can also store both bare cryoEM grids and autogrids. The four traditionally laid out pockets have 2 cross shaped slots - one slot holds both unclipped grids and autogrids comfortably and the perpendicular slot holds HPF hats. Because the workstations used for HPF often do not have cut outs to hold grid boxes so a lid can easily be screwed on and off, this new box has flats cut on either side so it can easily be held rigidly with a pair of tweezers and a lid can be screwed into place.
6-Pack includes one each of Grey, Green, Blue, Purple, Pink and Yellow. Boxes are laser marked with a unique serial number,
