Product Details
The Spinbar® stir bars are designed to work in conjunction with a magnetic stirring plate to create uniform, consistent, and thorough mixing of chemical solutions. Their contoured egg shape is ideal for use in round-bottom vessels and flasks, ensuring complete mixing and minimal contact when used in plastic containers, which minimizes scraping. The egg shape also provides a pivot point without a separate ring or abrupt change in contour, facilitating smoother mixing. Each stir bar features an Alnico magnet encapsulated in FDA grade, USP Class VI Teflon® brand PTFE coating for superior chemical compatibility. The magnets are egg-shaped to ensure more uniform strength throughout the bar, although the three smallest sizes are equipped with a cylindrical magnet. The stir bars are manufactured in a facility that is certified under ISO 9001:2015 by SGS, ensuring high-quality standards. Additionally, they are autoclave safe, and the Teflon® used is a registered trademark of The Chemours Company FC LLC, licensed by Bel-Art Products, Inc.
