Gridded microscope slides

These slides include a printed indexed grid as well as a frosted end. The ink is resistant to stains and common laboratory solvents. Each square grid occupies one low-powered area (approximately 100x magnification).  Such slides help users find an organism or a cell at any time. In all, there are sixty-four boxes. The slides are available with Poly-L-Lysine adhesives or can be purchased in plain (uncoated) form. 

The grid is 2mm square-16 mm overall. Numbers 1-8 and alpha number A-H.
