PTFE covered. For stirrers with rare earth magnetic core the magnetic attraction is 1,5 to 2 times stronger than conventional stirrers. The magnetic core is made from a combination of samarium and cobalt. The rare earth stirrers will continue to function at full strength for many years as the magnetism remains for longer.

• Very good chemical resistance
• Temperature resistant, suitable for use at high and low temperatures (−200 to +280 °C)
