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…

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…

Spinbar® Magnetic Sink Strainer is a simple solution to prevent your Spinbar® Magnetic Stirring Bars from going down the sink drain. Four strong magnets attract and hold stir bars Four legs on the underside prevent strainer from being dislodged by flowing liquid Long slits in…

PTFE-coated Features a pivot-ring for low-friction stirring

Octagon magnetic stirring bars with integral pivot ring are the most commonly used shape. Alnico magnet encapsulated in FDA Grade, USP Class VI Teflon® PTFE low friction coating; durable and inert Interrupted profile provides greater surface area and added turbulence when compared to…

These stirbars have polygon multifaceted surfaces that add turbulence relative to similar smooth size cylindrical bars. Center molded pivot ring minimizes the contact area between the bar and the vessel; reduces friction and chattering Marring of plastic containers is diminished Alnico…

…lengths to fit a wide range of vessels Autoclavable While 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…

Heavy duty bars for use in stirring large volumes of fluid in vessels 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…

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…

These stir bars have polygon multifaceted surfaces that add turbulence relative to similar smooth size cylindrical bars. Alnico magnet encapsulated in FDA Grade, USP Class VI Teflon® PTFE low friction coating; durable and inert Manufactured in a registered ISO 9001:2008 facility, as…

Spinbar® Octagon with integral pivot ring are the most commonly used magnetic stirring bar shape. Their interrupted profile provides greater surface area and added turbulence for efficient stirring when compared to the smooth surface of cylindrical bars and the pivot ring aids in reducing…

Octagon magnetic stirring bars with integral pivot ring are the most commonly used shape. Choose from red, yellow or blue. Alnico magnet encapsulated in FDA Grade, USP Class VI Teflon® PTFE low friction coating; durable and inert Interrupted profile provides greater surface area and…

Micro (Flea) magnetic stirring bars are designed for stirring small volumes in vessels such as vials, tubes and gradient makers. Particularly useful for environmental testing and life science applications in which small sample volumes need to be prepared and evaluated Alnico magnet…

Reduce frequency of spinout in viscous solutions or when stirring at high speeds. The high magnetic field strength of Samarium Cobalt (Rare Earth) magnets can provide up to three times stronger coupling vs. Alnico magnetic stirring bars.  Stronger coupling with the drive magnet keeps…
