Si-chips are opaque, of low electrical resistance and have surface properties equal to glass (including smoothness). They are also good substrates for growing or mounting cells. Si-chips are precleaned before packaging. Also ideal for imaging small particles due to low background signal.
4" wafer (#16010) is precut into 5 x 7mmm, 5 x 5mm, 10 x 10mm, 20 x 20 mm or 20 x 30mm chips that can be easily separated in the laboratory.
