The Wiper | SKR Element (VKS 95, VK 100) is an OEM PTFE wiper blade for the VKS 95 and VK 100 wiped-film distillation systems. The SKR wiper element spreads the feed material as a thin, uniform film across the heated evaporator surface, maximizing heat and mass transfer efficiency during molecular distillation. A worn or damaged wiper element reduces film uniformity and distillation yield; replace during annual preventative maintenance or whenever distillation efficiency declines.
