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…

Cylindrical alnico magnet sealed in polygon-shaped Teflon shell

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

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 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…

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…

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…
