Overhead Stirrer 40L is suitable for use with low, medium and high viscosity liquids including solid-liquids. overhead stirrers can be used in a wide variety of stirring and mixing applications such as chemical synthesis, pharmaceutical, physical and chemical analysis, cosmetics, food, healthcare, petrochemical, biotechnology, material science, cement, adhesives, polymers and more. Universal laboratory overhead stirrer uses microprocessor controlled technology to accurately control rotational speed between 50 and 2200 rpm. Precise speed control even under viscosity variations, torque monitoring indicates the changes in viscosity. Available in two sizes for stirring of up to 20 liters or 40 liters. Free software is downloadable to allow PC integration via a RS232 port for documenting and controlling all operating parameters. Safety Circuits designed to ensure no damage to the stirrer motor under overloading conditions. Slow start up to prevent sample spillage or overflow.
