SH Scientific Overhead Stirrer SH-OSA-25

SH Scientific Overhead Stirrer SH-OSA-25

Product Description

The SH-OSA-25 overhead stirrer from SH Scientific is an analog laboratory stirring device designed for reliable mixing of medium-viscosity liquids. It is suitable for chemical laboratories, pharmaceutical research, food testing, and academic research environments. The unit is engineered to deliver stable stirring performance while maintaining simple and user-friendly operation.

This overhead stirrer supports mixing volumes up to 25 liters of water equivalent. The integrated gear reduction system provides consistent torque for processing liquids with viscosities up to 70,000 mPas. Stepless speed control allows users to smoothly adjust the stirring speed to match different sample requirements.

The device uses durable ABS and aluminum housing for strength and long-term reliability. A motor over-heat protection system helps prevent damage during extended operation. The compact design allows easy installation on laboratory stands and supports impeller shafts up to 10 mm in diameter.
