Package Included：Size: 6.4mm×20mm/0.8 inches. Quantity: 10 pieces, shape: cylinder with pivot ring shape
DURABLE MATERIAL：Stir stick is made of Teflon and high-quality magnet. It is not easily demagnetized and lasts longer than other stir bars
Scientific Design：These stirring sticks have a pivot ring in the center. They are designed to hold an optimal position in containers with curved or uneven bottoms. The ring helps reduce vibration and wear, and reduces the effects of friction from contact with the vessel
Suitable for a variety of stirrers:Magnetic stir bars can be used with various types of magnetic stirrers or heating stirrers on the market
Wide range of uses：Stir sticks are widely used in scientific research, colleges and universities, industrial and agricultural laboratories and household use

Use along with a compatible Erlenmeyer Flask and Stir Plate to do Stir Plate Yeast Starters.
Why a Stir Plate? The constant motion of a stir plate integrates oxygen, puts yeast in constant contact with nutrients, relieves built up CO2 and generally helps yeast to grow more rapidly. That also means smaller starters.
Why get 10? Generally, you’re going to save money buying in bulk. Having these on hand allows you to do multiple starters at once and… you’ll have spares if you mistakenly dump your stir bar into your fermenter.
