SH Scientific Overhead Stirrer SH-OSD-25

SH Scientific Overhead Stirrer SH-OSD-25

Product Description

The SH-OSD-25 is a digital overhead stirrer from SH Scientific designed for reliable mixing of low to medium-viscosity liquids in laboratory environments. It is commonly used in chemical laboratories, pharmaceutical research, cosmetic formulation, and academic research applications.

This model supports a maximum stirring capacity of 25 liters (water equivalent). It can handle liquids with viscosity up to 70,000 mPas. The belt-type gear system provides stable torque and smooth rotation for consistent mixing performance.

The unit features a digital controller with a back-lit LCD display. Users can monitor speed and timer settings clearly during operation. The system includes a digital fuzzy controller with touch buttons and a rotary control for precise speed adjustment.

Safety features include overload protection and a motor heat protector. These functions help protect the equipment and maintain safe operation during extended mixing processes.
