Formvar Stabilized with Carbon (5-10nm)


  • Substrates, Support Films
    for Transmission Electron Microscopy Grids

    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.

  • Formvar, Stabilized with Carbon

    A Formvar film covered with a "light" layer of carbon. The heat and electrical conducting properties of carbon help to stabilize the Formvar films when exposed to the electron beam. This is a resilient, all-purpose specimen support film, ideal for mounting thin sections and for applications using lower ranges of magnification. The 200M-TH grids (Prod. No. 01803 and 01803-F,01803G and 01803G-F), plus the 300M-TH grids (Prod. No. 01804G and 01804G-F) are thicker and more rigid than normal and useful for many applications - particularly where a lot of grid handling is involved.
