BOLA Moon-Shaped Stirrer Shafts EX
Material: Temperature resistance: Chemical resistance: Conductivity:
PTFE-EX from -200 °C to +250 °C ++ very good 106 Ohm
Product description:
PTFE-EX jacketed stainless steel shaft, tilting half-moon stirrer blade with double-sided groove and access for stirrer shaft completely made of static dissipative PTFE-EX. Good chemical resistance, the product is only exposed to PTFE-EX
Applications:
Tangential flow with little turbulence. The tilting half-moon blade is ideal for stirring in round- bottom flasks with ground-joint necks. Earthing is made for example via a stirrer bearing made of PTFE-EX (Cat. No. C 423-.. on page 165).
