They are designed to meet requirements of laboratories demanding wide flexibility of stirring operations. These stirrers are available in various models. The choice of model will be dependant on the batch size / volume to be stirred.
The Remi RQ-122/D is a specialized high-performance overhead stirrer designed for medium-duty laboratory applications. Built with a high-torque AC/DC universal motor, this unit provides exceptional stirring power for volumes up to 20 liters. The "D" in its model name stands for Digital Speed Indication, which allows for precise monitoring of the RPM, ensuring that complex chemical reactions and formulation processes remain consistent. Its robust construction is complemented by an epoxy-coated body that provides long-term resistance against corrosive chemical vapors and accidental spills.
One of the standout features of the Remi RQ-122/D is its hollow shaft design, which enables users to adjust the height of the stirring impeller without having to move the stirrer head itself. This adds a layer of convenience and safety when working with different vessel heights. The stirrer is equipped with a stepless speed regulator, allowing for smooth acceleration from 50 to 2500 RPM. This wide range makes it versatile enough for both delicate mixing and intense homogenization. Furthermore, the built-in thermal overload protection ensures that the motor remains safe during extended periods of operation in busy pharmaceutical or research laboratories.

Frequently Asked Questions
1. Can the RQ-122/D handle thick oils?
Yes, it is designed with a high-torque motor that can handle medium-viscosity fluids like light oils and syrups effectively.
2. Does it include a digital timer?
The /D model specifically provides a digital RPM display. For timer functions, external timers or the "Plus" series models are recommended.
3. Is the stand included with the stirrer?
Typically, the unit is sold as the stirrer head. You will need a compatible heavy-duty stand and boss-head for secure mounting.
4. How do I adjust the impeller height?
The hollow shaft design allows the stirring paddle to be passed through the motor and locked at any desired height using the chuck.
