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.

So far, So good
Works well. I'm not experiencing problems like some other users. No splitting, or uneven spinning.

Reliable and Efficient: PTFE Magnetic Stirrer Mixer Stir Bars
The PTFE Magnetic Stirrer Mixer Stir Bars have been an excellent addition to my laboratory equipment. The set includes eight pieces, each 35 mm (1.38 inches) in length, which is perfect for various stirring needs. These stir bars are incredibly reliable and efficient. The PTFE coating ensures they are chemically resistant and easy to clean, which is crucial for maintaining the integrity of my experiments. They work seamlessly with my stir plate, providing consistent and smooth stirring every time. The white color makes them easy to spot in different solutions, and their size is ideal for most standard lab containers. Overall, I am very impressed with the quality and performance of these stir bars. They are a must-have for any laboratory looking for dependable and durable stirring tools. Highly recommended!

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.

Good quality, they work better than the original
I use these to make my plant tissue culture media and to help clean my explants and they work well, maybe better than the one that came with my stirrer... They're just a little bit longer. Helpful to have extra so I don't have to pull them out and clean them between steps.

As described
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.
