Bel-Art Spinbar Teflon Octagon Magnetic Stirring Bar, 38.1 x 8mm, Yellow

Designed for stirring large volumes in vessels such as drums and tanks. A molded pivot ring minimizes the contact area between the bar and the vessel, thus reducing friction and chattering. Marring of plastic containers is diminished Multifaceted surface adds turbulence relative to similar size smooth cylindrical stirring bars Ideal for use with Cool Stir®Large Volume Stirrer, H37028-0001; capable of stirring volumes up to 190 L (50 gallons) Alnico magnet encapsulated in FDA Grade, USP Class VI Teflon®brand PTFE Coating – Superior Chemical Compatibility Manufactured in a registered ISO ...

The Spinbar®Restrainer fits ergonomically in one hand, and when placed alongside the outer wall of a mixing vessel it retains and secures the stirring bar in position. Confined stirring bar can be retrieved from the vacant container without contaminating the solution after the vessel is drained Strong magnet restrains magnetic stirring bars up to 80mm (3") long

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 the stirring bar centered and rotating effectively Octagon shape with pivot ring creates strong turbulence with minimal chattering and friction Encapsulated in bright green, FDA grade, USP Class VI Teflon®PTFE; easy to differentiate from other stirring bars Autoclave safe Manufactured in a registered ISO ...

Designed for small volume mixing 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 encapsulated in FDA Grade, USP Class VI Teflon®brand PTFE Coating; Superior chemical compatibility Manufactured in a registered ISO 9001:2015 facility, as verified by SGS certification Autoclave safeTEFLON®is a registered trademark of The Chemours Company FC LLC and used under license by Bel-Art Products, Inc.

Used in conjunction with a magnetic stirring plate, Spinbar®stir bars create uniform, consistent, and thorough mixing of chemical solutions. Contoured egg shape is ideal for use in round-bottom vessels / flasks; ensures complete mixing Offers minimal contact when used in plastic containers; minimizes scraping Egg shape provides pivot point without a separate ring or abrupt change in contour for smoother mixing Alnico magnet encapsulated in FDA Grade, USP Class VI Teflon®brand PTFE Coating; Superior chemical compatibility Magnets are egg-shaped for more uniform 'strength' throughout the ...
