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

Half 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.

Full 3 mm grids: Available in Cu with 2 different tapered slot openings on each of 4 rows (5) lettered slots at ~ 14 +/- 4 microns and (4) numbered slots at ~ 6 +/- 4 microns wide. The lettered/numbered slots are +/- 100 microns long.Please Note: The metal 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."

​​The patented* EXpressLO-Z™ grids are made from nanocrystalline diamond (NCD) and offer a low-Z alternative to metal grids for reduced X-ray fluorescence and overlaps with high temperature stability.

Half 3 mm EXpressLO-Z™ grids: Available in NCD with 3 different tapered slot openings with top opening (1) P slot at ~ 100 +/- 1 microns, (6) lettered slots at ~ 15 +/- 1 microns and (6) numbered slots at ~ 4 +/- 1 microns wide. The P slot is ~ 150 micron long from the outer grid surface and the lettered/numbered slots are ~ 100 microns long.

Full 3 mm EXpressLO-Z™ grids: Available in NCD with 2 different tapered slot openings on each of 4 rows (8) lettered slots at ~ 15 +/- 1 microns and (7) numbered slots at ~ 4 +/- 1 microns wide. The lettered/numbered slots are +/- 100 microns long.
