Carbon and Graphite for Evaporation
Carbon
Fiber and Cord
For carbon coating. The fiber will give you thin to medium coatings. The cord will give you thick coatings.

Graphite
is the stable form of carbon. Graphite is one of the softest; diamond is one
of the hardest minerals known to man. Carbon is harder than graphite. For TEM
and SEM applications, graphite is recommended.
Carbon /graphite films are most usable in TEM and SEM due to its value characteristics: uniformity amorphous and high transparent to electron beams. Because of low molecular weight and their unique structure (graphite have a sheet like structure, where the atoms all lie in a plane), carbon/graphite films have excellent mechanical stability, and even film thickness is about 1 – 2 nm. Our carbon/graphite rods are CVP™ (Chemical Vapor Process) purity and spectrographic grade, grade 1, produced to ASTM tolerances or even tighter.

Carbon
Rod Sharpener
Produces 1mm diameter carbon tip on ¼" or 1/8" carbon rods. Two carbide blades shape the tip. A gauge is included for adjusting the blade gap. Dust catcher is easily removed for cleaning or blade adjustment. The device is driven be a durable electric motor, producing a smoother and more uniform carbon tip than any hand sharpener.
The kit includes a blade gauge and a 1/8" rod adapter.
