Several innovations in the multipurpose EM (MEM) grid boxes make it easy to use, have enabled greater secure storage, and integrated the documentation.

These new innovations are:
- “Tree” shaped TEM grid storage cavity almost completely removes the possibility of damaging the TEM grids. There is a separating wall between the grid storage cavity and the tweezers cavity, so the tweezers will only be able to grip the edge of the grids.
- There is an additional slider with a window between the cover and grid storage boxes. This exposes only 4 grids at a time and does not allow grids to fall or “jump” out of the storage box.
- An integrated grid storage record card is placed in a dedicated slot on the back of the MEM grid box
- The body of the storage box is made of white plastic, which provides a good contrast. The coverlid and the slider with a window are made of clear plastic, enabling good visibility.
