Apparatuses
The inherent heat resistance and chemical stability of precious metals make them indispensable for various devices, including crucibles used in oxide single crystal growth, as well as analytical instruments utilized in the laboratory field. Our company offers products in a wide range of standard shapes and also specializes in custom-made equipment, even in small quantities.
We can provide processing for not only platinum but also the challenging-to-process material, iridium.
Platinum apparatuses - Equivalent to JIS Standards
- Overview
- Our platinum crucibles for chemical analysis are available in two types: "General Use Platinum Crucibles" and "Platinum Crucibles for Coal and Coke." Both types comply with the JIS H 6201:1986 standard.
- Chemical composition
- Platinum: 99.9% or higher, Other Elements (Palladium, Rhodium, Ruthenium, Iridium, Gold, Silver, Copper, and Iron): less than 0.1%
- *Excerpt from JIS H 6201:1986
- *Our standard is 99.95% platinum or greater.
