Grid storage box with identification number

Storage for 100 grids (2.3 or 3.05mm) in deep, diamond-shaped wells.  

The box and lid are precision injection moulded from plastics chosen for their smooth sliding action. To further ease grid handling, the plastics are anti-static treated. A central access position in the lid reduces the number of grids exposed when selecting any particular grid.

Once stored, the grid can be located by its ?map reference'. Each well has a blue printed letter and number. (Blue is chosen for its visibility under normal 'safelight' conditions.) The reference and a brief specimen description are entered on the grid record card for that box.

The 100-grid box is also available numbered: each box has a unique number printed on the face and one end.
