Magnetic Stir Bar 8 x 30 mm PTFE Applications:

• Used to stir liquids beakers and flasks of small to medium size 
• Increased heat transfer during stirred operations by maintaining minimum temperature in contact with heated surface
• Less chance of boil overs as stir bar acts as nucleating site for bubbles
• Mixing of solids and liquids to enhance dissolution rates
• Maximizes evaporation rate by increasing the surface area exposed to the air through development of a vortex and drawing addition air into the mixing that becomes saturated with water and carries the solvent out of the vessel.
• Utilized to mix two or more phases together increasing the surface contact when extraction between phases is desired.
