PTFE blade attached to coated  (⁵/₁₆") diameter shaft. For low speed, higher viscosity mixing, ideal for round bottom flasks.

• PTFE blades – Excellent chemical (including acidic and caustic) resistance
• Poor adhesion; materials release easily from impeller – Easy to clean
• One piece – Quick to install and begin mixing

A tangential flow PTFE impeller for low speed, higher viscosity mixing. The 80 mm (3¹/₈") blade is attached to an 8 mm (⁵/₁₆") diameter PTFE-coated shaft, designed for use in round bottom vessels and reaction flasks. 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.
