After overcoming complex technical challenges, the team at Wellspring MEMS is thrilled to announce a major milestone: the successful development of a high-precision hollow fiber spinneret featuring three concentric hollow nozzle pins. This breakthrough opens the door to the fabrication of triple-layer composite hollow fiber membranes—establishing a powerful new platform for next-generation membrane architectures with significantly enhanced functionality and performance.

In membrane research and development, success often depends on one simple question: How quickly and reliably can you produce high-quality membrane samples? Anyone who has worked with flat-sheet membrane casting knows the challenges. During casting, dope solution can accumulate along the sides of the doctor's knife, contaminating the rollers and forcing operators to stop, clean the equipment, and restart the process. Even worse, thickness variations across the membrane width c

MEMS is preparing several research devices lined up for the test-run, ready to be delivered to our customers. Almost every customer has their own specific requirements regarding standards, functions, instruments, parts and components. To meet these diverse needs, we first create 3D design simulations during the design process. After the device is manufactured, we conduct Factory Acceptance Tests (FAT) together with the customers to ensure everything meets their expectations.
