Spin Bar Teflon Flea Half Inch

The Half Inch PTFE Flea Stir Bar is a micro magnetic stirring accessory for small laboratory vessels and low-volume mixing tasks. Measuring approximately 1/2 inch by 1/8 inch, its compact size allows it to operate in containers where a standard-length stir bar may be too large. Available color variants include blue, red, and yellow, subject to current inventory.

The Half Inch PTFE Flea Stir Bar has a PTFE exterior surrounding a magnetic core. PTFE is commonly used for laboratory stir bars because its smooth surface provides useful resistance to many chemicals and separates the internal magnetic material from the liquid. Confirm compatibility with the specific substance, temperature, and cleaning procedure before use.

Mixing performance of the Half Inch PTFE Flea Stir Bar depends on vessel geometry, liquid depth, viscosity, magnetic stirrer strength, and selected speed. Its small size is intended for compact vessels rather than large-volume mixing. If the bar loses coupling, jumps, or rotates irregularly, reduce stirring speed and confirm that the vessel and liquid conditions are suitable for a micro stir bar.

Inspect the PTFE surface before use and remove the stir bar from service if it becomes cracked, deeply scratched, distorted, or otherwise damaged. Clean it using a method compatible with PTFE and the material being handled. Small stir bars can be easy to overlook during pouring or cleaning, so account for the bar before emptying a vessel.
