Carbon Planchets
Spectroscopically pure carbon Grade 1 (graphite) planchets with total impurities equal to or less than 2ppm with each single element 1ppm or less.

Carbon Discs on Pin Stubs
Carbon planchets with a 1.6mm thickness mounted on standard pin stubs, supplied in the #16709 pin mount storage box.
Convenient and ready to use.
Provides a durable and economical solution for SEM/EDS microanalysis or low emission surface backscatter imaging applications needing light element surface.
Surface roughness of the carbon discs is 0.05-0.01um, material is spectroscopically pure carbon with total impurities less than 2ppm.
The aluminum stub underneath the carbon disc provides more rigidity that the carbon stubs.
Available for 12.7, 18 and 25.4mm (1/2″, 0.7″ and 1″) pin stubs.
Sold in storage box with 10 of the 12.7mm pin stubs and 8 of the 18 or 25.4mm pin stubs.

The highly polished carbon planchets have a smooth, polished finish on one side with much less surface porosity than the standard carbon planchets.
The material for the cabon discs is spectroscopically pure carbon Grade 1 (soft graphite) with total impurities equal to or less than 2ppm with each single element 1ppm or less.
Properties same as Carbon Planchets above.
The polished planchets are 1.4 to 1.5mm (0.055″ to 0.06″) thick.
Available in the popular 12.7mm (1/2″) and 25.4mm (1″) diameter.
Available in all of the same sizes as our unpolished carbon planchets.

Vitreous Carbon Planchet
Lapped surface on one side for smoothness, also known as glassy carbon or glass-like carbon.
For analytical SEM/EDX, X-ray analysis and chemical analysis applications.
Vitreous carbon is an advanced materials of pure carbon combining glassy and ceramic properties with those of graphite.
Impermeable to gases and liquids, high purity, corrosion resistant, thermal stability in air up to 600 C and in vacuum or inert gas up to 3,000 C.
Good electrical conductivity, low thermal expansion and extreme resistance to thermal shock.
Hard and strong (hardness = 230 HV1).
Applications in the fields of chemical analysis, metallurgy, crystal growth, medical technology and in glass and ceramics research.
