The Weewooday 30 mm PTFE Magnetic Stirrer Mixer Stir Bar is engineered for high performance in laboratory settings. Made from premium PTFE and magnetic steel, it offers exceptional resistance to heat, corrosion, and abrasion, ensuring reliable and efficient mixing across a variety of applications.

## Description

30 mm/ 1.18 Inch PTFE magnetic stirrer mixer stir bar, white color, stir rod magnetic, laboratory bar, stir plate bar, stir plate magnet  Instructions: Place the magnetic stirrer bar in a beaker, graduated cylinder or other container, place the container on the platform of the electromagnetic heating stirrer, and then turn on the switch of the electromagnetic heating stirrer. The magnetic stirrer will generate rotational force to drive the substance to rotate quickly. In this way, the substance is completely mixed, and the substance can be concentrated by heating.  Multiple uses: Laboratory bar can be applied with various types of magnetic stirrers or heating stirrers. Stir plate magnet is widely applied in scientific research, universities, laboratories in the industrial and agricultural sectors, and is often applied to stir mixed substances.  Specifications: Color: as pictures shown Material: PTFE and quality magnetic steel Size: 8 x 30 mm/ 0.31 x 1.18 inch  Note: Please allow a little error on the size due to manual measurement.

## Questions & Answers

**Q: Can these be autoclaved?**
A: I would have to assume so. They’re scientific instruments. Generally, with a few exceptions, there designed to be regularly sterilized.
I regularly send mine through a pressure cooker at 15 PSI in liquid cultures

**Q: Could these be used with a sensor for an alarm system (Simplisafe)?  I have double hung windows so need a slim magnet to put opposite the sensor. Thx**
A: Probably, but I suspect it would be much easier to use one of these that's the size you want: https://www.amazon.com/s?k=neodymium+disc+magnets&crid=3RBE9SKKGYW9W&sprefix=Neodyn%2Caps%2C235&ref=nb_sb_ss_ts-doa-p_5_6

**Q: is there any possibilities that these could degrade and leak into the water? any easy way to see it? thanks**
A: There is nothing to leak. Inside is a solid magnet. It's possible that after using them a long time, friction could wear out the plastic coating, but that will probably take years and you'll see it slowly degrading. Just take a quick glance before you use them and if they look like they are in good condition, they are.

**Q: Is there a "flat" side of the magnet, or are both sides curved?**
A: Both sides are curved.
