A complete family of PFA and PTFE vessels and instruments for element analysis — engineered for extraordinary corrosion resistance, high-temperature stability, and a trace-metal background low enough for ICP-MS, isotope analysis and semiconductor-grade work.
The LabStory Fluoropolymer Labware line is designed and quality-assured in Singapore and manufactured to LabStory specification by an established fluoropolymer OEM partner. Every vessel is engineered from high-purity PFA or PTFE — materials chosen for corrosion resistance against strong acids, strong bases and hydrofluoric acid, and for a trace-metal background clean enough for the most demanding analytical work.
From digestion and evaporation through to storage and acid purification, this range covers the full sample-preparation chain used in geochemistry, isotope analysis, biomedical research, environmental monitoring, semiconductor manufacturing and microelectronics.
Both materials resist strong acids, strong bases, aqua regia and hydrofluoric acid — the choice usually comes down to transparency, temperature and application.
