Frequently Asked Questions (FAQs)
1. What surface finish is required for aseptic storage vessels?
For aseptic storage applications, interior surfaces typically require electropolished finishes with Ra values between 0.2μm and 0.4μm (8-16 μin) to minimize product adhesion and potential contamination. The specific finish requirements depend on the product being stored and applicable regulatory standards.
2. How do aseptic storage vessels maintain product sterility during long-term storage?
Our vessels incorporate multiple features to maintain sterility, including electropolished surfaces, sanitary connections, sterilizable vent filters, positive pressure maintenance systems (often using nitrogen blanketing), and compatible CIP/SIP systems for validated cleaning and sterilization between uses.
3. What is the difference between standard storage tanks and aseptic storage vessels?
Aseptic storage vessels incorporate specialized features such as superior surface finishes, sanitary connections, sterile filtration for vents, crevice-free design, and materials selected specifically for biocompatibility and cleanability, which are not typically found in standard storage tanks.
4. What types of monitoring systems can be integrated with aseptic storage vessels?
Our vessels can be equipped with various monitoring systems including temperature sensors, pressure transmitters, level indicators, conductivity meters, pH probes (where applicable), and sampling systems—all designed with sanitary standards in mind to prevent contamination.
5. How are aseptic storage vessels sterilized between uses?
Our vessels are designed for Steam-in-Place (SIP) sterilization, which uses pure steam to achieve sterility, as well as Clean-in-Place (CIP) systems for validated cleaning protocols. The specific sterilization method depends on the vessel design and the requirements of your process.
6. Can aseptic storage vessels be used for cold storage of temperature-sensitive products?
Yes, our aseptic storage vessels can be equipped with cooling jackets, insulation packages, and temperature control systems to maintain specific storage temperatures for sensitive products while preserving sterility.
7. What documentation is provided with aseptic storage vessels?
We provide comprehensive documentation including material certifications, surface finish reports, weld maps and qualifications, pressure test reports, sterilization validation support documentation, as well as design and manufacturing documentation to support regulatory compliance.
8. How do you handle pressure control in aseptic storage vessels?
Our vessels incorporate sterile pressure relief valves, pressure monitoring systems, and often nitrogen blanketing systems to maintain positive pressure while preventing contamination. All pressure-control components are designed with aseptic principles in mind.
9. What is nitrogen blanketing and why is it important for aseptic storage?
Nitrogen blanketing creates an inert atmosphere above the product in the vessel, preventing oxidation and microbial growth by displacing oxygen. The positive pressure created also provides a barrier against environmental contaminants, helping to maintain product sterility.
10. What is the typical lead time for a custom aseptic storage vessel?
Lead times vary based on vessel complexity, size, and current production schedule. A typical custom aseptic storage vessel may require 12-16 weeks, but we work closely with clients to develop realistic project timelines that align with your operational needs.
