SPI Collection of Grid Storage Boxes
Protect your valuable TEM grids for later inspection and verification analysis and counting
Comments about TEM grid storage boxes:
We offer two brands of TEM grid storage boxes, the SPI Supplies® Brand and the BEEM®
Brand (Slide-A-Grid™/Twist-A-Grid™ and Dial-A-Grid™ styles respectively). Both brands
of boxes were designed and engineered by professional TEM users with very definite
ideas about the proper way to store and retrieve grids. Both are designed to
hold standard grids of 3.05 mm diameter in the range of thicknesses which will
fit into a typical TEM specimen stage.
There are three significant differences between these products:
1. Obviously, the Dial-A-Grid holds 24 grids, while the Twist-A-Grid
holds 50, and the Slide-A-Grid holds 100 grids.
2. The cover of the Dial-A-Grid box exposes one grid at a time; the cover
of the Twist-A-Grid box exposes 3 and the Slide-A-Grid box exposes 5 grids at a time.
3. The individual spaces in the Slide-A-Grid and Twist-A-Grid boxes require
that the grids be placed in a particular orientation; the individual spaces
in the Dial-A-Grid boxes allow the user to choose either of two orientations.
There are two basic requirements for the space that holds the individual grid:
1. Obviously, the space must hold the grid.
2. The space must allow the user to pick the grid up using tweezers.
That is, it must hold the grid by its periphery but allow access to the grid.
Both products meet both of these requirements, although in somewhat
different ways. It really comes down to the preference of the individual user.
And it is for that reason why we present these different possibilities
