Elliptical (Egg-Shaped) Spinbar Magnetic Stirring Bars

“Eggcellent” for Round Bottom Flasks

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 bar, except three smallest sizes have a cylindrical magnet
Manufactured in a registered ISO 9001:2015 facility, as verified by SGS certification
Autoclave safe
