SH Scientific Overhead Stirrer SH-OSA-60

Product Description

The SH-OSA-60 overhead stirrer from SH Scientific is an analog laboratory mixing device designed for reliable stirring of medium to high-viscosity liquids. It is suitable for research laboratories, chemical processing, pharmaceutical development, and pilot-scale mixing applications.

This overhead stirrer can handle mixing volumes up to 60 liters of water equivalent. The integrated gear reduction system provides strong torque, allowing the unit to mix thick samples with viscosities up to 150,000 mPas. Its stepless speed control enables smooth adjustment of stirring speed, making it easier to maintain stable mixing conditions for different materials.

The compact design combines ABS and aluminum materials for durability and lightweight handling. The motor includes an over-heat protection system to ensure safe operation during extended mixing tasks. According to manufacturer specifications, the unit also supports impeller shafts up to 10 mm in diameter and operates within a speed range of 50 to 800 rpm.

Overall, the SH-OSA-60 provides strong torque, reliable speed control, and stable mixing performance for demanding laboratory mixing applications.
