Electron Microscopy Sciences Lacey Carbon Film with Ultrathin Formvar 3-4 nm thick on 400 mesh Nickel Grid
The continuous ultrathin formvar film on lacey carbon allows for the thinnest support film that still has adequate strength to withstand electron microscope specimen preparation. The less than 3nm thick film lies across a carbon lacey film supported by a mesh grid. The size of the holes in the lacey film differ widely from batch to batch but are generally in the range of ¼ µm to 5µm, which gives the equivalent support of at least 6000 mesh grid.
Specimen material lying over the covered holes can be imaged in the TEM with practically no interference from the carbon film supporting it. This product is ideal for looking at nanotubes, virus particles and other small particulate material.

Electron Microscopy Sciences R 2/2 Holey Carbon Films on Grids, Grid: Copper. Mesh: 400., 10/PK
QUANTIFOIL is a perforated support foil with pre-defined hole size, shape and arrangement that has advantages in electron microscopy (EM) or low-energy electron point source (LEEPS) when compared with conventional holey film. QUANTIFOIL with circular holes is used in cryo-electron tomographic reconstruction. The roundness of the holes is advantageous with respect to the formation of an ice layer of constant thickness. Hole size is 2 µm. Space between holes is 2 µm. Center to center is 4 µm. Types with 2 µm holes are recommended for magnifications between 30.000x and 40.000x. Grid: Copper. Mesh: 400 .
