Dry silica crucible

Full Description. The QC (Quartz-crucible) of high purity Silica (SiO2) material, is a transparent container which is resistant to extremely high temperatures as well as being chemically inert to get non-contaminated results. These vessels should also be ideally resilient to thermal shocks

Silicon carbide crucibles are suitable for smelting and melting precious metals, base metals and other metals in an induction furnace. They are used at a temperature reaching 1600 degree celsius. The silicon carbide crucible offers a uniform and consistent temperature when melting and has a high strength and resistance to cracking. The uniform temperature gives a high quality molten metal

Samples dry-ashed in fused silica crucibles were compared to samples subjected to the hot trichloracetic acid-acetic acid extraction method, which gave results not significantly different if the tissue was first minced. However, calcium was incompletely extracted by the hot acid from whole segments of liver weighing about 0.2 g
