组件规格

定义
A pharmaceutical-grade sterile sampling valve component designed for hygienic extraction of liquid or semi-solid samples from processing vessels, tanks, or pipelines in controlled environments. It maintains system integrity during sampling operations through sterile barrier technology, preventing microbial ingress and cross-contamination while ensuring operator safety.
工作原理
Utilizes a double-membrane or septum-based sterile barrier system. When sampling, a sterile sampling device pierces the primary septum while the secondary barrier maintains isolation. After sample collection, the system self-seals to preserve sterility. Some designs incorporate steam sterilization ports or use disposable sterile interfaces.
材料
316L stainless steel (body)PTFE or silicone septaEPDM or Viton sealselectropolished surfaces (Ra ≤ 0.8 μm)optionally with sanitary finishes per ASME BPE standards.
Size
1/2" to 2" nominal
Connection
Tri-clamp, sanitary flange, or threaded
Cleanability
CIP/SIP compatible
Surface Finish
Electropolished to ≤ 0.8 μm Ra
Pressure Rating
Up to 10 bar
Temperature Range
-20°C to 150°C
Sterility Assurance Level
SAL 10^-6
标准
ISO 2852ASME BPEFDA CFR 21 Part 211EU GMP Annex 1

常见问题

How often should sampling ports be replaced or maintained?

Septum membranes should be replaced per manufacturer guidelines (typically 100-500 cycles) or after visible damage. Full valve maintenance depends on usage but generally follows annual validation schedules with integrity testing.

Can these ports be used with viscous fluids?

Yes, but may require larger bore sizes or specialized septum materials. For high-viscosity fluids, consider ports with reinforced septa or dual-seal designs to prevent leakage.
