PTFE Three-Blade Propeller Stirring Paddle, 350 mm Shaft and 57 mm Propeller (CAT#: STEM-BC-3477-ZJF)

This PTFE three-blade propeller paddle is designed for electric overhead stirring. Its stainless-steel shaft core is covered with a chemically resistant PTFE sleeve. The fixed three-blade propeller generates substantial liquid circulation. Forward rotation directs the sample downward along the central axis. Reverse rotation directs the central axial flow upward. This reversible circulation supports mixing through the upper and lower regions of the vessel. The paddle is intended for medium-speed processing of low- to medium-viscosity samples. PTFE provides nonstick performance, heat resistance, corrosion resistance, and low friction.
