Stir Bars, Pyrex Glass, High Torque, Long Lasting, Spectrophotometer Cuvette, Protective Capsule and Centering Beaker with Cover

  Overview

The Spinbar® Pyrex Glass, Spinbar® High Torque, Spinfinity® Long Lasting, Spinbar® Cuvette, Spinbar® Capsule stir bars and the Centering Beaker with Cover offer different materials for different performance, designs for specific tasks, or protective and centering features.

The Spinbar® Pyrex Glass encapsulated magnet has zero absorption and can handle temperatures to 274 °C, the Spinbar® High Torque uses a rare earth Samarium Cobalt magnet to increase torque transmission two to three times over standard stir bars, the Spinfinity® Long Lasting stir bar use a more abrasion resistant construction for abrasive slurries, the Spinbar® Cuvette conveniently fits a standard 10 mm spectrophotometer cuvette (as well as round bottom test tubes) and delivers aeration free mixing, the Spinbar® Capsule is for gentle mixing and protection of probes, and the Centering Beaker with Cover is designed to control the position of the stir bar.

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.

Pyrex Glass High Torque Long Lasting Cuvette Capsule Centering Beaker
Rose Scientific has a large selection of magnetic stir bars for every application, for general magnetic stirring, high temperature stirring, viscous solutions or high speed stirring, abrasive slurries or extended stirring, stirring in large or very small containers and gentle stirring in tissue culture applications.

The Spinbar® Octagon, Round, Polygon, Flea Micro, Egg Shaped (Oval) and 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. The Spinvane® Angled Vane, Half Round Semicircular, Tapered Half Round Semicircular, the Spinring® Balancing Ring, the Spinfin® Finned and the Spinfin® Double Finned add to the choices. More solutions are provided by the Spinstar® Star Shape, Spincross® Cross Shape, Spinwedge® Triangular, Spinbar® Saturn. Circulus® Barbell, and Floating Iman, or the Spinbar® Pyrex Glass, Spinbar® High Torque, Spinfinity® Long Lasting, Spinbar® Cuvette, Spinbar® Capsule stir bars and the Centering Beaker with Cover.
