PFA material is resistant to strong corrosive solutions such as strong acids and alkalis. The bottle cap adopts a threaded sealing design, without the need for a bottle stopper, with no liquid leakage, and can be sealed for long-term storage of high-purity reagents and standard samples. Widely used for the digestion and medium low pressure dissolution of semiconductor new material experimental samples, supporting trace analysis experiments such as ICP-MS/ICP-OES analysis. #Reactionvessel # traceanalysis # SeriesReactiondevice
