## Description

Packing list: ● 1 x Length 10mm Diameter 4mm ● 1 x Length 15mm Diameter 6mm ● 1 x Length 20mm Diameter 7mm ● 1 x Length 25mm Diameter 7mm ● 1 x Length 30mm Diameter 7mm ● 1 x Length 30mm Diameter 8mm ● 1 x Length 35mm Diameter 8mm

Review: The 35mm, the two 30mm, and the 15mm worked great! 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: No complaints after having these sit in liquid culture for 2 weeks, no signs of rusting. Nice to get different sizes but the little one is REALLY little so make sure you don't lose it.

## Questions & Answers

**Q: What is the max temp you can heat to ?**
A: Melting point for PTFE (Teflon) is 326 C or 620 F.  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
