CAFRAMO PTFE Collapsible Blade 40 mm dia - Pinned to 400 x 8 mm Shaft

A radial flow PTFE impeller for high speed, low viscosity mixing in narrow neck flasks. The blades are attached to an 8 mm (⁵⁄₁₆ in) diameter PTFE-coated shaft, fanning out with agitation to a maximum diameter of 40 mm (1 ⁹⁄₁₆ in). The stainless steel core of the shaft provides stability. PTFE (polytetrafluoroethylene) can be used under the most adverse conditions. This high performance coating is insoluble, non-contaminating and has exceptional thermal resistance. It is easy to clean, does not scratch other surfaces and is unbreakable.
