Picofiltration products employ a patented DNA template to form the nano-sized pores used for filtration. Our DNA technology provides control over the pore size. This allows filter products that range from loose nanofiltration (<1500 Daltons) down to high purity picofiltration (<500 Daltons).

Filter Element Housings:
Cerahelix housings are designed for individual and multi-element configurations. Our standard housings are made from 316 stainless steel. We also offer custom housings for industry specific processes including solvent filtration applications.
Laboratory Test Systems
Cerahelix sells and leases bench-top cross flow filtration systems for small scale research and development testing needs. The system’s innovative housing design provides a flexible approach to scalability by allowing an increase in membrane surface area from 0.01 m2 to 0.40 m2 without sacrificing optimum cross flow velocities or increasing flow rate requirements. This provides a 40X increase in filter surface area that can be tested using the same test stand.
