The multifaceted magnetic stirring bar surface adds turbulence relative to similar size smooth cylindrical stirring bars. Ideal for single use applications mixing radioactive reagents or when cross contamination might be a concern Alnico magnet encapsulated in FDA Grade, USP Class VI PTFE…

…bars provide maximum stabilization of the magnetic stirring bar with the addition of a removable “hoop” around a standard octagonal bar. Best suited for larger open-neck vessels, such as buckets and beakers Friction fit of the "hoop" and bar allows them to spin…

Spinplus® magnetic stirring bars add speed and efficiency to mixing operations. The "+" shape creates a deep vortex and provides stable, quiet operation Alnico magnet encapsulated in FDA Grade, USP Class VI Teflon® PTFE low friction coating; durable and inert …

Cylindrical magnetic stirring bars offer excellent centering and smooth running characteristics. Small removable pivot ring in the center adds to their versatility Pivot ring minimizes the contact area of the bar to the vessel, reduces friction and lessens marring of plastic containers …

Flexible, Teflon® rod with a powerful Alnico Teflon® coated magnet for retrieving magnetic stirring bars from containers or non-magnetic sink drains and traps. Flexible white rod is 33cm (13") long Autoclavable

…Magnetic Stirring Bar is a polystyrene capsule containing a 30 x 8mm (1.18 x 0.31") polygon magnetic stirring bar that spins freely inside the capsule while being prevented from spinning off center and ‘wandering’ on the base of a vessel. Containment of the stirring bar…

Pyrex® Spinbar® glass encapsulated Alnico magnet stirring bars are useful for high temperature applications up to 274°C (525°F). Completely smooth surface offers "zero absorption"; easy to clean Meets US Pharmacopoeia specifications for Type I Borosilicate glass …

Spinwedge® magnetic stirring bars provide strong turbulence at fairly low speeds and are well suited for churning sediment or dissolving salts. Wedge shape is designed to plow up sediment for thorough dispersion Sharply angled broad face provides strong mixing action, perfect for…

Alnico magnets seated in Teflon® Oval shape reduces friction and increases effectiveness in round-bottom flasks.

These egg-shaped stirring bars are designed especially for use in round-bottom vessels as they spin unrestricted by the vessel contour. Particularly well suited for round bottom flasks; shape ensures complete mixing Offers minimal contact when used in plastic containers Egg shape…

…many magnetic stirring bars are impeded by powders in a liquid, the Saturn Spinbar overcomes this problem. A large bulb in the bars center lifts the stirring bars ends while spinning thereby reducing surface contact area and allowing the bar to spin with decreased drag. The stirring bar is available…

…on large magnetic stirring machines such as the Cool Stir Large Volume Stirrer, H37028-0001 or other large machines. Will fit into vessels with a minimum neck diameter of 32 mm Multifaceted surface adds turbulence relative to similar size smooth cylindrical stirring bars Alnico magnet…

This magnetic stirring bar fits into the standard 10mm light path cuvette and provides rapid vertical and horizontal mixing with a minimum of vortexing when placed on a magnetic stirring machine. Centrifugal pumping action, generated by the cross channels in the upper face, mixes without…

…Motor-less Magnetic Stirrer: The magnetic coil technology works on the inductive principle with alternative current (AC) as its driving force. The generated moving magnetic field drives the spinning of the stir bar in the vessel. Several advantages come with a motor-less magnetic stirrer…
