Spiral Stirrer

The Spiral Stirrer is designed for applications that require gentle, controlled agitation, making it ideal for medium to high viscosity products (1,000–10,000 cP) and formulations that are particularly delicate. It is perfect for processes where the goal is creating a homogeneous solution or keeping particles in suspension rather than intensive blending.
