6 pack 7x30mm(diameterxlength) C-type magnetic stir bar in one package.
Chemical Resistance - Stir bars are coated with covering, which is chemical inert to most chemicals and solvent, such as strong acid, alkali, water and organic solvent,also helps reduce friction and wear while spinning.
No adhesiveness - they have the lowest surface tension among solid material, and will not stick to any substance.
Easy to Use - Place inside a container of liquid that is seated on a magnetic stirrer.The cylindrical shape and smooth surface will reduce friction and improve smooth rotation
Widely Application - perfect for stir a liquid or solution in scientific research, universities, laboratories in the industrial and agricultural sectors, and also can be applied to stir mixed substances
