The Labnet PTFE-Coated Magnetic Stir Bar by Labnet International is a 1 x 2.5 cm magnetic stir bar with a PTFE coating. Labnet lists it as an accessory for its AccuPlate digital stirrers and hotplate stirrers, which use strong permanent magnets to couple with the stir bar. Researchers and lab managers order it to replace lost or worn bars or to keep spares on each stirrer.
