Quantifoil® Finder Grids

Finder grids have reference patterns and numbering systems to aid re-location of a specific feature on another microscope.
An alpha-numerical code identifies 48 blocks of 6 cells each (3 x 2 pattern), delineated by thicker grid bars. Each block’s code is attached to the baseline of its center-bottom cell, letters representing rows and numbers representing columns to quickly return to the same spot on the grid on any instrument.

• Easy to navigate during grid scanning, with identification symbols close to areas of interest in the grid mesh
• Minimize beam obstruction with wide 200 mesh
• Minimize grid regions lost to numbering by sharing identification symbols between squares or including them within grid bars
• Easy to distinguish grid orientation with asymmetric grid square, rim and/or centre marks
• Simple-to-read alphanumeric labelling systems
