Product Description
Keep the stir bar coupled to the drive magnet even at higher speeds. Strong ALNICO magnets resist spin-outs that interrupt mixing, so solutions stay moving consistently whether you are dissolving salts, preparing buffers or holding a reaction at temperature on a hot plate stirrer. Fewer spin-outs mean less babysitting of the stirrer.
This listing is for catalog number 120897: Magnetic Stir Bar, PTFE, Smooth, 35x8mm, White, Pack of 10. Each bar is a sintered ALNICO magnet sealed in chemically inert PTFE that protects both the magnet and the sample and wipes clean easily. The smooth octagonal shape works well in flasks and beakers with concave bottoms, and the bars tolerate temperatures up to 225°C. Lengths of 10, 25, 30 and 35 mm are offered. LIGHT LABS stocks the Heathrow Scientific line, so racks, replacement parts and consumables are easy to reorder.
