Permanent Magnet CD (PMDC) Stirrers are specially designed for routine laboratory work, research and development, QA analysis and sample preparations. Stirrers have uniform speed control with digital RPM indicator which gives speed read outs, valuable for applications where process validation and reproducibility is required.
RQ-121 / D, RQ-12 6 / D and RQ-129 / D models use direct drive motors & are ideal for day to day laboratory use with aqueous & low viscosity liquids such as light oils.
The Remi RQG-126/D is a heavy-duty geared overhead stirrer specifically designed for tasks requiring extremely high torque at lower speeds. The "G" in its model designation indicates a "Geared" drive system, which provides the mechanical advantage needed to stir high-viscosity materials such as heavy oils, thick polymers, and dense chemical suspensions that would stall a standard motor. This unit is integrated with a digital tachometer (D) for precise speed feedback, allowing laboratory technicians to maintain strict process control. Built with a PMDC motor, the RQG-126/D offers consistent stirring performance even when the liquid viscosity changes during a reaction.
Safety and versatility are hallmarks of the RQG-126/D. It features a hollow shaft design, enabling easy height adjustment of the stirring impeller without disturbing the motor mount. This makes it highly adaptable for various vessel sizes, from small beakers to large carboys up to 25 liters. The body is coated with a chemical-resistant epoxy finish to protect against corrosion in aggressive laboratory environments. With a stepless electronic speed regulator and built-in thermal overload protection, this geared stirrer is a reliable workhorse for pharmaceutical research, food processing, and material science laboratories worldwide.

Core Applications
The Remi RQG-126/D is perfect for homogenizing viscous pastes, preparing emulsions in cosmetics, and mixing pigments in the paint industry. Its geared mechanism is essential for pilot plant operations where high torque is more critical than high RPM.
Frequently Asked Questions
1. Why choose the Geared (G) model over the standard?
The geared model provides much higher torque at lower speeds, making it capable of stirring thick, viscous liquids that a standard stirrer cannot handle.
2. Does it maintain speed under load?
Yes, the PMDC motor combined with the gear system is designed to maintain a stable RPM even as your mixture becomes thicker.
3. Is it noisy during operation?
Despite its high power, the geared system is engineered for quiet operation suitable for professional lab environments.
4. Can I use different impellers?
Yes, the 10mm chuck accommodates various stirring paddles including anchor, propeller, and turbine types.
