Designed for efficient and effective mixing in simple blending, solids suspension, high-viscosity, and gas-liquid applications, Lightnin GP2 (General Purpose) and Lightnin LB2 (LabMaster and BioMixer) use brushless DC motor and have automatic overload and over temperature protection. Impellers can be adjusted via stainless steel chucks and shafts. Facilitated operation and control ensure desired performance, which is bolstered via integrated digital control and feedback system.
