Perfect
These little stir bars work perfectly, they spin quietly, stay centered, and the PTFE coating feels durable. The different sizes make it easy to match whatever beaker or container you’re using. Great value for a reliable set.

Stirs 32oz Liquid Culture easy peasy.
They are large enough to stir 32oz LCs on low to medium. They also work with smaller jars (1pint). They are strongly magnetic and the coating holds up to daily stirring. I havent had any issues with Sterilizing them or the coating pitting. They work well with my basic small stir plate.

Have used for 5+ years been using for mycology Liquid Culture prop. in 1/2 gal ball jars.
These work great, expensive, yet 'renewably reusable', and also just work. I use these in 1/2 gal ball liquid culture jars, and with simple 28 dollar stir plates. With the right setting, these kick up and make a vortex in 1-2 seconds, and don't get lost or tossed on my plates. 1" to 1.125" is the right for this application. These work fine and are reusable, or giftable, or tossable.

These are the exact size I was looking for, I only wish the magnets were a bit stronger. But these will do for now. Thank you.
