The 25mm, the 20mm, and the 10mm didn't work well, as they seemed unbalanced, so they were noisy and it was very hard to get them to work. I am using these with the INTLLAB Magnetic Stirrer. Review: A nice case to keep them all together. - I bought these to replace my LOST set... And the LOST ones turned up right AFTER two uses of the new ones. These work very well for me and have a nice little case. SO... I hope not to lose any of these. ## Features - ✔ CHEMICAL RESISTANT - Teflon PTFE material can be used with corrosive chemicals, including acid and base - ✔ POWERFUL - Teflon (PTFE) casing helps reduce friction and wear while spinning - ✔ EASY USE - Place inside a container of liquid that is seated on a magnetic stirrer - ✔ PORTABLE FOR WIDE USE: perfect for stir a liquid or solution in scientific research, industry, agriculture, health and medicine, homebrew, etc - ✔ 100% MONEY BACK GUARANTEE - We want you to be 100% Satisfied with your purchase.

You want to stay at the safe side of that with a good margin. The magnet itself his much higher, but should be covered by the encapsulation at all times. **Q: Incluye las pinzas y el estuche? viene como en la imagen? gracias** A: En el que yo compré no incluía pinzas ni estuche **Q: What's the difference of type b vs. type c?** A: Looks like the type b’s have a ring around the center to help it spin easier ## Customer Reviews ### ⭐⭐⭐⭐⭐ Most worked great! *by U***R on February 16, 2023* The 35mm, the two 30mm, and the 15mm worked great!
