Frequently Asked Questions (FAQs)
1. What surface finish is required for sterile processing vessels?
For aseptic processing applications, interior surfaces typically require electropolished finishes with Ra values between 0.25μm and 0.5μm (10–20 μin). The specific requirements may vary based on the product being processed and applicable regulatory standards.
2. How do you ensure that sterile processing vessels remain sterile during operation?
Our vessels incorporate design features such as sanitary connections, sterilizable air filters, and positive pressure maintenance systems. They are also designed for validated Clean-in-Place (CIP) and Steam-in-Place (SIP) operations to ensure sterility is maintained.
3. What is the difference between a standard pressure vessel and a sterile processing vessel?
Sterile processing vessels incorporate specialized features such as superior surface finishes, crevice-free design, full drainability, sanitary connections, and materials selected specifically for biocompatibility and cleanability, which are not typically found in standard pressure vessels.
4. Can your vessels be validated for pharmaceutical manufacturing?
Yes, our sterile processing vessels are designed to support validation requirements, including Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ). We provide comprehensive documentation packages to facilitate these validation activities.
5. What sterilization methods are compatible with your sterile processing vessels?
Our vessels are designed to be compatible with steam sterilization (including SIP), chemical sterilization, and filtration sterilization approaches. The specific design features are tailored to the sterilization method used in your process.
6. How do you prevent biofilm formation in sterile processing vessels?
We employ multiple strategies, including electropolished surfaces to minimize bacterial adhesion, crevice-free design to eliminate harborage points, complete drainability to prevent standing water, and material selection that resists biofilm formation.
7. What documentation is provided with sterile processing vessels?
We provide comprehensive documentation including material certifications, surface finish reports, weld maps and qualifications, pressure test reports, riboflavin testing for CIP validation, as well as design and manufacturing documentation to support regulatory compliance.
8. Can sterile processing vessels be designed for specific temperature requirements?
Yes, our vessels can be designed with jacketing, insulation, and temperature control systems to maintain specific temperature requirements, from cryogenic applications to high-temperature sterilization processes.
9. How are your vessels tested for sterility assurance?
Our vessels undergo rigorous testing including pressure hold tests, helium leak detection, riboflavin testing for CIP effectiveness, and can be designed to support customer-specific sterility validation protocols.
10. What is the typical lead time for a custom sterile processing vessel?
Lead times vary based on vessel complexity, size, and current production schedule. A typical custom sterile processing vessel may require 12–20 weeks, but we work closely with clients to develop realistic project timelines that align with your operational needs.
