The HSC-H-OS overhead stirrer mixes liquids of low to high viscosity in laboratories, research centres and production. It is used in pharmaceuticals, biotechnology, chemicals, food and cosmetics. Four models handle batches of 20 to 100 litres and viscosities up to 100,000 mPa·s, with 40 to 100 N·cm of torque. You set the speed from 30 to 2,200 rpm (30 – 1,600 rpm on the largest model) with coarse and fine adjustment, accurate to ±1 rpm, and an LCD shows speed and time. It stops by itself and shows the fault if the motor is overloaded.
