Lab Safety Supply Inc Magnetic Stir Bar Octagon 10.31 mm 6.35 mm PK10

Octagonal Stir Bar Kit

This pack supplies ten PTFE-coated Alnico stir bars for routine laboratory mixing. Each bar measures 10.31 mm in diameter and 6.35 mm in length with an octagonal profile that promotes strong vortex formation. The white coating resists chemical attack and simplifies visual retrieval from vessels. The product is new and ships as a complete PK10 assortment.

Capacity and Headroom

Ten bars provide enough spares for parallel experiments or immediate replacement when a bar is lost or damaged. The octagonal geometry couples efficiently with standard magnetic drivers across common beaker sizes. The Alnico core maintains magnetic strength through repeated autoclave cycles. The set runs out when a protocol demands a different diameter, length, or pivot-ring design.

Upgrade Path

This kit replaces worn or undersized cylindrical bars that slip at higher stirring speeds. The jump is worth it when a lab standardises on a single octagonal dimension to simplify inventory and reduce cross-contamination risk. Buyers who need larger diameters, pivot rings, or colour-coded lengths will require a different assortment.
