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…

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…

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…

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…

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…

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 …

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…

Spinstar® magnetic stirring bars create a deep mixing vortex at relatively slow speeds. Star shape is designed to fit the inside diameter of most commonly-used beakers Perfect for applications requiring slow, thorough mixing Alnico magnet encapsulated in FDA Grade, USP Class VI…

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…

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 …

Two 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…

The Capsule 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…

These stirbar assortments come in a convenient storage box and provide instant availability of these highly popular Teflon® PTFE encapsulated Alnico magnets. Choose from Octagon, Cylindrical, Polygon, Micro, Egg-Shaped or Spinplus® shaped assortments FDA Grade, USP Class VI…
