Frequently asked questions about the stir bar
What is the magnet used for?
It goes in the flask or vessel on a magnetic stirrer. The stirrer makes the magnet spin so the liquid is mixed continuously. This is common for yeast starters.
Can the magnet handle boiling and cleaning agents?
Yes. The PTFE coating has high chemical resistance, and the magnet withstands -200 to +280 °C.
Why should a yeast starter be stirred?
Stirring keeps the yeast in suspension and releases CO2, so the yeast multiplies better.
