Overhead Stirrer

The Overhead Stirrer is a versatile and precise laboratory tool designed for stirring liquids with maximum control and safety. Equipped with a brushless DC motor, it offers a wide speed range from 30 to 2000 rpm and ±1 rpm accuracy for consistent results. The LCD screen displays real-time speed, torque, and sample temperature. Its adjustable stirring paddle clamp, forward/reverse/alternating functions, and overload protection ensure flexibility and safety across a variety of applications. Ideal for laboratories handling viscosities up to 10,000 mPas, this overhead stirrer supports precise, reliable mixing for samples up to 15 liters.

Product Features
