4"(10Cm) Wafer Precut To 5X7mm, 187 Chips/Wafer

Silicon Chip Specimen Supports

These mounts are perfect for applications where the surfaces of carbon or aluminum stubs may cause interference. They have surface properties equal to glass, are opaque, and possess low electrical resistance.


  • Examining small particles with fine structure.
  • Mounting cell structures.
  • Determining contrast and resolution of "in-the-lens" field emission SEMs.

All chips are packaged clean and polished on one side. Attach to any type of specimen stub. Each chip is pre-cut from a 4" (10 cm) wafer.
