PELCO® TEM Grid Support Film Application Guide

PELCO® TEM grid Support Films of Formvar, Formvar/Carbon, Carbon, and Silicon Monoxide are available on the following 3.05mm O.D. grids: 0.4 x 2mm single slot Cu, 75 mesh Cu, 200 mesh Cu,Ni or Au, 200 mesh Hex Mo, 300 mesh Cu, Ni or Au, 300 mesh Hex Mo, and 400 mesh Cu, Ni, Au, Al, Ti and stainless steel.

Support films on the finer mesh grids can withstand considerable handling during specimen preparation. Those on slot and 75 mesh grids require more gentle handling and are ideal for those applications requiring large viewing areas without grid bar interference.

Our popular line of PELCO NetMesh™ Grids (our trademarked lacey films) are available on 200, 300 and 400 mesh grids. These robust films allow for viewing of specimens without interference from underlying support film material.

The complete PELCO® line of support films meets the requirements of most applications in all fields of electron microscopy.
