Electron Microscopy Sciences Formvar/Carbon Film 25-50 nm/3-4 nm thick on Thin Bar Square 1000 mesh Nickel Grid
A formvar coated grid, stabilized with evaporated carbon film. This type of coating is excellent for specimen support, especially for ultra thin sections. Coated grids are optically checked followed by batch testing in the electron microscope. Packed in grid storage box. NOTE: All film is laid on the shiny side of the grid. Formvar is 25 to 50 nm thick with a 3 to 4 nm carbon coating.
Grid: Nickel

Electron Microscopy Sciences PolarStat™ Plus Embedding Medium
This formulation is especially well suited for Mohs cryostat sectioning. It freezes at optimum cutting temperatures of -10 deg C and below. No residue is left on slides during the staining procedure, thereby eliminating undesirable background staining.
Electron Microscopy Sciences Graphene Oxide Support film on Quantifoil R1.2/1.3, Gold, 400 mesh
Graphene Oxide (GO) support film is a super thin (<1nm), naturally hydrophilic layer placed over the support film on grids. Pre-treatment of GO Support Films is unnecessary - by default, the hydrophilic surface spreads particles evenly across the grid. A hydrophobic surface can be achieved by heating in the air.
It works well with holey carbon, lacey carbon, and Quantifoil grid types, effectively spanning the gaps. It is less expensive than graphene to produce due to complexity of graphene manufacturing and has a better background contrast than graphene resulting in higher resolution. Nearly transparent in electron beam and barely visible under optical microscopes. Regular batch checking ensures correct coverage of monomers.
Note: plasma cleaning or glow discharge will damage the support film.

Electron Microscopy Sciences Quantifoil Holey Carbon Film R 2/4 on Gold 200 mesh Grid
QUANTIFOIL is a perforated support foil with pre-defined hole size, shape and arrangement. It has advantages in electron microscopy (EM) or low-energy electron point source (LEEPS) microscopy 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. The whole size chosen depends on the magnification used, and on whether or not one wishes to include support film in the image. Assessment of the image quality is easier when foil is included in the picture, because the power spectrum of a foil is stronger than that of unsupported ice.
