A new concept in finder grids
Rows are labelled alphabetically, both on the rim of the grid and at the corners of each of the cells.
To index the location of a specimen for later, or for viewing by a colleague, the binary code, and alphabetic symbol of the cell are noted for easy, accurate location in the future.
To locate any particular spot of specimens on the grid, simply match the alphabetic and numeric co-ordinates.
Columns are numbered from 1-20. A 5 digit binary numbers appears on the bottom of each of the squares.
