Sleek and Powerful Overhead Laboratory Stirrers Designed for Years of Service
To build great stirrers you start with great engineers. Four E’s USA Overhead Stirrers were designed with our engineering team working closely with customers mixing emulsions, suspensions, and water and oil mixtures. These stirrers use advance controls to provide constant mixing speed through low and high viscosity solutions. Whether you are working with polymers or polyphenols Four E’s USA stirrers were designed to exceed expectations.

Intelligent design
Four E’s takes mixing seriously. Each overhead stirrer includes everything you need to start suspending. The through shaft design allows for adjustable impeller height and securely attaches the implement to the high-end brushless motor. We also have over a dozen accessories to ensure that your experiment has the tools necessary for success. The bright display alternates between the set speed and the actual speed to provide real-time process feedback. Contact our product specialist to determine what model is best for your lab
Safety is Paramount
How much safety is too much for an overhead stirrer? We don’t know but we would rather err on the side of caution. Four E’s USA has multiple safeties built in for the operator and the device. If the unit detects excess torque a proprietary overload safety kicks in. There are also auto cut off and temperature sensing circuits for additional protection. The intuitive interface has easy to read codes and an audible alarm for fault detection and diagnosis.
