Magnetic Stir Bar 11 x 52 mm PTFE Applications:

    • Used to stir liquids beakers and flasks of medium to large size to 10 L
    • 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.
