Chien grids, single hole, copper

A Chien grid is used to pick up many individual sections or ribbons and to transfer them onto another grid. It can also be formvar coated as a receiving grid for examination of a large number of sections. When formvar coated, it will support 2 or even 3 parallel ribbons of serial sections, with no obscuring grid bars.

Hole size 50% greater than the largest slot grid.

There are two slits in the rim area which allow it to be easily bent with forceps to make a tab, while keeping the remainder of the grid surface flat prior to picking up ribbons.
