Gridded photoetched circular coverslips

These coverslips are made from German made, pure white glass, and photo-etched for a permanent gridded pattern.

The unique grid pattern it contains squares of 500um, numbered 1 to 200.  (Other sizes have up to 520 coded squares). The squares are visible under brightfield and have high contrast when using phase contrast microscopy. Picture shows the pattern of the squares.

These slips are used to facilitate mounting of micromanipulated cells or chromosome spreads.

* Using No. 2 (0.17-0.25mm) thickness cover slips
* Suitable for insertion into most 6-well plates
* Adaptable to most microscope mounting plates
* Facilitates observation of actively growing squares
