Laboratory Magnetic Stirrers
Manual mixing often results in non-uniform mixtures in experiments, which often results in problematic results. To combat this, a laboratory magnetic stirrer will mix the liquid in a stable manner using magnetic mixing bars. These bars are made from PTFE and a fine alnico that is suitable for strong acids and bases.
GUOHUA provides magnetic stirrers with single stirring points or multiple stirring points. A stirrer with multiple stirring points will carry out simultaneous mixing in multiple beakers at a variety of speeds. Eight different magnetic stirrer types are shown below for customers to choose from.
