TL-ULTRA Specification
Features:
The Electrospinning Machine (TL-ULTRA) features an innovative design where all functional components are externalized. All metal parts and electrical mechanisms are equipped with insulated casings for isolation and protection. This ensures that the internal electric field within the machine is pure and free from any additional electromagnetic interference. As a result, the fibers produced are consistently stable and uniform.
The TL-ULTRA is designed with extensive functions and super clean environment. It comes equipped with a variety of nozzles and collector devices, allowing for dozens of different combinations in the production of various forms and arrangements of nanofibers. This versatility make the TL-ULTRA an excellent choice for advanced nanofiber fabrication.
