Scale-up made easy

Hollow fiber filter TFF modules are offered with a broad range of sizes, surface areas and membrane chemistries designed to facilitate easy scale-up from small volume process development and R&D applications to commercial production. During scale-up, adding more fibers to process larger volumes enables consistency in the length of the filtration flow path even while the surface area of the filter is increased.
