Glass Magnetic Stir Bar General:
Use these glass coated stir bars to avoid problems with oxygen uptake/release in the teflon coating used for most stir bars. This is especially important for oxygen methods in tiny volumes. Another advantage of glass coating is easy cleaning (autoclavate) and resistance to acids, dissolvents etc.

Glass Magnetic Stir Bar Optional:
Use these glass coated stir bars in our mini respirometers chambers.

Pyrex glass-encased magnetic stir bars are completely non-reactive, leak proof, and nonabsorbent
Handles temperatures up to 525°F (274°C)
