1. One-piece molded,Smooth inner surface, no residue, translucent for visibility.
2.Extremely low leachables and extractables,with minimal metal element background.
3.Capable of withstanding extreme temperatures (-200 to 260°C) and resistant to both acids and alkalis.
4.U-bottom design enables uniform heating and gentle reactions, improving sample transfer and cleaning. Suitable for geochemical exploration sample analysis.
（V-bottom design concentrates samples at the tip, enabling faster dissolution, improved reaction efficiency, and easier sample collection and transfer.）
