​The patented EXpressLO 3 mm tapered slotted half grids* directly supports either a thick or electron transparent specimen manipulated via ex situ lift out. 

​There are 2 geometries of grids available:

ORIGINAL: These Cu grids have 15 specimen positions, 8 "lettered" small slots and 7 "numbered" large slots. The large slots are ~ 22 +/- 4 microns wide and the small slots are ~ 14 +/- 4 microns wide. The slots are ~ 30 microns in length from the top surface.

NEW PGrids: Available in either Cu or Ni with 3 different tapered slot openings with top opening (1) P slot at ~ 120 +/- 4 microns, (6) lettered slots at ~ 14 +/- 4 microns and (6) numbered slots at ~ 6 +/- 4 microns wide. The P slot is ~ 150 micron long from the outer grid surface and the lettered/numbered slots are ~ 100 microns long.

Please Note: The grid manufacturing process produces results which may vary.  While we try our best to offer consistent sized slot openings, some variability is inevitable and grids are therefore provided "as-is."
