Specimen Holder

It is designed to accommodate even a little quantity of material and to provide maximum thermal effect. It could be of Pt, stainless steel, Ni, Ag and alloy like as Pt-Rh. certain ceramic materials like as sintered alumina, fire clay, silica, heat resistant glass and even graphite have been recommended as material specimen holder for a sample below investigation and reference material such (α-alumina).
