State-of-the-art sanitary housings
The new Millistak+ 316L stainless steel filter housings are designed for high-capacity liquid clarification. Offered in multiple sizes to accommodate varying production process volumes, Millistak+ housings complement the removal capacity, dependable performance, and efficiency of our extensive line of Millistak+ and Millistak+ HC filtration cartridges.
Certified to 9001 Quality Standard
Quality Management Systems of all Millipore manufacturing sites are certified to the ISO® 9001 quality standard. Following the principles of customer satisfaction and continuous improvement, these sites consistently produce the highest quality products available.
All housings are shipped with a Certificate of Quality that confirms conformance to stated requirements and lists the appropriate QA lot release criteria. Additionally, an Inspection Certificate (3.1.B) is supplied in accordance with EN 10204 3.1.B.
Innovative Design Features
The Millistak+ housing is equipped with a unique compression mechanism that maintains consistent sealing pressure on the cartridge without the use of threads. This unique arrangement uses a removable compression tool to quickly install or remove a compression cup and spring assembly in the top of the housing. By eliminating the conventional threaded post and nut, change out can be performed in just minutes every time.
