The 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.

The Quartz crucibles are acting as vessels for holding chemicals as the specific thermal or chemical process performed. These are efficient for use as laboratory crucible as well as in industrial applications. These have increasingly replaced the conventional Rotosil crucibles, which were earlier more prominently used in industrial and research applications.

The quartz crucible comes with a lid and without the lid or cap as per requirement. The capacity of it varies from 5ml to 1000ml. There is two main type of the quartz crucible, one is the low form (Curvy Shape), and another is tall form (Cylindrical Shape) crucible. The researched can operate it efficiently at around 1150 degree Celsius.
