Bel-Art Spinbar Teflon Polygon Magnetic Stirring Bar, 2 1/2 x 1/2", White, without Pivot Ring

A 10-pack of the most commonly used Spinbar®Octagonal Magnetic Stirring Bars in a variety of colors and sizes. Eight-sided Spinbar®Octagonal Magnetic Stirring Bars provide greater surface area and added turbulence when compared to smooth cylindrical bars Integral pivot ring on each stirring bar aids in reducing friction and chattering 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 Included Spinbar®Restrainer fits comfortably in one hand ...

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 ...

Integral pivot ring on each stirring bar aids in reducing friction and chattering. Included Spinbar® Restrainer fits comfortably in one hand and retains Spinbar® Magnetic Stirring Bars up to 80 mm (3") long by holding them against vessel walls. Eliminates splashing hazards when pouring. Spinbar® sizes: 2 each - 1/2 x 1/8", 1/2 x 5/16", ...

Spinring®stirring 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 as a unit "Spin out" is virtually eliminated Stirring bar remains centered in vessel Octagon shape creates a deep vortex without splashing or chattering Alnico magnet encapsulated in FDA Grade, USP Class VI Teflon®brand PTFE Coating – Superior Chemical Compatibility Manufactured in a registered ISO 9001:2015 ...

Heavy duty bars for use in stirring large volumes of fluid utilizing 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 Multi-faceted surface adds turbulence relative to similar size smooth cylindrical stirring bars 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 certificationAutoclave safeTEFLON®is a registered trademark of The ...
