PTFE Gas Sampling Valve
Featuring fully-lined PTFE construction for precision gas sampling in corrosive/ultra-pure systems. Its purged-seal technology with metal-free flow paths achieves zero adsorption sampling, maintaining gas integrity for critical monitoring in semiconductor and biopharma processes.
Key Features:
✔️ Non-Adsorptive Flow Path：Mirror-finished PTFE prevents gas molecule adsorption
✔️ Self-Purging Seal：Dual-isolation design enables pre/post sampling cleaning
✔️ SIP/CIP Compatibility：Withstands steam sterilization up to 250°C
✔️ Dead Volume-Free Switching：Plug-type structure ensures >99.5% displacement
Critical Applications:
▸ In-situ specialty gas analysis in semiconductor process chambers
▸ Exhaust gas monitoring for bioreactor O₂/CO₂ metabolism
▸ Decomposition gas sampling in Li-battery electrolyte systems
▸ Quality control during ultra-high purity electronic gas production
