compact and lightweight design for easy handling and saving bench space. 4E's overhead stirrer has a sleek and modern appearance that complements any laboratory setting. provides efficient and reliable stirring performance for various laboratory applications. enables easy adjustment of stirring speed and torque, ensuring precision and accuracy in mixing solutions. Ideal for use in research, development, and quality control laboratories in industries such as pharmaceuticals, chemicals, and food science. 4E's USA Lab overhead stirrers are used for mixing high viscosity substances up to 100,000 mpas, ensuring consistent mixing regardless of any changes in viscosity. These stirring devices can maintain a constant stirring speed, which helps to prevent any potential disturbances or inconsistencies in the mixing process. Overhead stirrers feature a powerful motor that provides a high level of torque, enabling them to handle even the most viscous materials with ease. Another benefit of using 4E's overhead stirrers is that they can be easily adjusted to suit different mixing requirements or viscosities, making them versatile tools for many applications. 4E's USA stirrers are designed to mix or stir liquid samples with precision and control. The maintenance-free brushless DC motor does not require regular maintenance and provides high efficiency. Overload protection is a safety feature that automatically shuts down the stirrer when it senses an excessive load or strain on the motor, preventing damage or accidents. Over-temperature protection is another safety feature that turns off the motor when it detects high temperatures, protecting not only the motor but also the samples being stirred. 4Es USA laboratory mixers are designed with a push-up rod to save time when handling samples, as the design allows for easy and quick changes of the sample being stirred. The push-up rod feature eliminates the need to manually lift and adjust the stirrer, reducing the risk of spills and ensuring consistent mixing. The go-through design of the push-up rod ensures that it can pass through the stirrer without interfering with its operation, making it a convenient and user-friendly tool. By choosing an overhead stirrer with a push-up rod, researchers and lab technicians can streamline their workflow, save time, and increase their overall productivity.
