Homogenizers
Lab Stirrers & Homogenizers are essential instruments widely used for sample mixing, blending, and emulsification. Although both are designed for mixing operations, they serve different purposes:
Stirrers is mainly applied for macroscopic-scale mixing, while Homogenizers is required when achieving fine dispersion, particle size reduction, or nano/micro-scale emulsification. Choosing the right equipment depends on the sample characteristics—such as viscosity, composition differences, and particle size distribution—as well as the desired final mixing result.
Based on their working principles and structures, laboratory stirrers can be mainly divided into three categories: Magnetic Stirrers and Overhead Stirrers.

Overhead Stirrer-High Torque

Homogenizer
A homogenizer is an instrument used to forcibly mix immiscible substances (such as liquid–liquid or liquid–solid ), break down particles, and ultimately produce a uniform, stable, single-phase mixture — a process known as “homogenization.” Suspensions and emulsions remain stable without phase separation after homogenization, which cannot be achieved by ordinary stirrers.
Choosing a high-speed homogenizer is not meant to replace a stirrer, but to perfectly complement it functionally.
The stirrer is responsible for preliminary mixing, dissolution, and gentle stirring during reactions.
The high-speed homogenizer is responsible for precision processing, addressing the most critical issues of stability, uniformity, and fineness.
