About Rose

Stir Bars, Spinbar® Octagon, Round, Polygon, Flea Micro, Egg Shaped (Oval) and Disposable

  Overview

The Spinbar® Octagon, Spinbar® Round, Spinbar® Polygon, Flea Micro, Spinbar® Egg Shaped (Oval) and Spinbar® Disposable Stir Bars available from Rose Scientific are the most popular of the magnetic stir bars and are available in the widest selection of sizes, for general magnetic stirring.

All but one of the Spinbar® Octagon stir bars have built in pivot rings, the Spinbar® Round stir bars have a built in pivot ring or tapered ends, the Spinbar® Polygon stir bars have some with built in pivot rings, some without, and include some large and giant sizes. The Flea Micro stir bars cover mixing in small vessels and test tubes. The Spinbar® Egg Shaped or Oval stir bars have a natural pivot point and do well in round bottom flasks. The Spinbar® Disposable stir bars are designed for single use and offer inexpensive insurance against cross contamination.

Prices are for each, but volume pricing is available. Rose Scientific has a minimum order requirement, so it is important to inquire about volume purchases or to combine orders with the purchase of other equipment.
