TEM grid holder for 4 grids, M4 cylinder

This TEM grid holder holds up to 4 TEM grids. It enables imaging and analyzing specimens on TEM grids in the SEM. For EDS applications it is beneficial to place thin films on a TEM grid or small particles on a TEM grid with a support                     film. This can significantly reduce background in the EDS spectrum and increase detection limits of the EDS detector. Hole size in the top and base is 2.1mm dia. Opening angle on the holes in the top and base is 120° to reduce electron scattering and improve X-ray collection. Overall diameter is 18mm, overall height is approximately 25mm with a stand-off pin mounted on a ?15 x 10mmx M4 Hitachi mount. The stand-off pin minimises electron and X-ray scattering contribution from the stage. TEM grid locations are numbered. Material: vacuum grade aluminium with brass screw. 

Screws used are 6-32 x 1/8 hex set screw, 316 stainless steel and 2-56 x 3/16 flat head screw, brass.
