Support Film on Grids

Support Film on grids has become a main product line for us since the demand for high quality coated grids has increased. To make your microscopy work easier and to save you a great deal of time we offer you a complete line. All of our coated grids are optically checked followed by batch testing in the EM. Packed in grid storage box. All the grids below (except for the Beryllium Support Films) are also available with the following options:
– Molybdenum grids in place of Au, Cu, or Ni
– As Silicone free
– With ultra-thin thickness (thickness can be requested)
– Extra thick thickness

NOTE: All of our film is laid on the shiny side of the grid.

Formvar/Carbon Film:
A formvar coated grid, stabilized with evaporated carbon film. This type of coating is excellent for specimen support, especially for ultra thin sections. The thickness range is as follows:
Standard Option A: 10nm Formvar and 1nm Carbon
Standard Option B (SB): 10nm Formvar and 3-4nm Carbon
Standard Option C (SC): 10nm Formvar and 20-30nm Carbon
Ultra-Thin Option A (UA): 5-6nm Formvar and 1nm Carbon
Ultra-Thin Option B (UB): 5-6nm Formvar and 3-4nm Carbon
Ultra-Thin Option C (UC): 5-6nm Formvar and 20-30nm Carbon
Thick Option A (TA): 15-20nm Formvar and 1nm Carbon
Thick Option B (TB): 15-20nm Formvar and 3-4nm Carbon
Thick Option C (TC): 15-20nm Formvar and 20-30nm Carbon
Extra Thick Option A (EA): 25-50nm Formvar and 1nm Carbon
Extra Thick Option B (EB): 25-50nm Formvar and 3-4nm Carbon
Extra Thick Option C (EC): 25-50nm Formvar and 20-30nm Carbon

How do Nickel and Copper Grids React with Periodic Acid?

Periodic Acid + Ni

Ni-Periodate + H2

Periodic Acid + Cu

Cu-Periodate + H2

In this case you should use Gold Grids.
