Yamato LR Series Laboratory Stirrers (High-Torque Overhead Mixing)

Conquer your most viscous chemical formulations. The Yamato LR series features a maintenance-free brushless DC motor for high-torque overhead mixing. Contact Renetech!

The Product Description

Relentless High-Torque Mixing for Viscous Fluids When your laboratory is formulating heavy polymers, mixing thick cosmetics, or synthesizing large-volume chemical batches, a standard magnetic stirrer will instantly stall out. Viscous liquids require raw, top-down mechanical torque. You need a dedicated, heavy-duty overhead stirrer capable of pushing through thick resistance without burning out the motor.

The Yamato LR Series is the ultimate high-performance Laboratory Stirrer. Manufactured to strict Japanese engineering standards, it is designed to mount securely above your reaction flasks and provide relentless, high-torque agitation for your most demanding fluid mixtures.

The Brushless DC Motor Advantage The heart of the LR series is its advanced Brushless DC Motor. Standard laboratory stirrers use carbon-brush motors that wear down over time, require frequent maintenance, and generate internal sparks (which is highly dangerous when mixing volatile solvents).

By utilizing a brushless DC design, the LR series is completely maintenance-free and spark-free. It provides incredibly stable rotational speeds—even as the viscosity of your chemical mixture changes during the reaction—ensuring your formulations are perfectly blended without stalling.

Two High-Performance Configurations We provide the exact rotational speed and torque configuration your laboratory requires. Both models are highly robust and easily adaptable for Malaysian electrical setups (via step-down transformer):

• LR500A (The High-Speed Mixer): Equipped with a heavy-duty 100W brushless motor, this unit operates at higher rotational speeds ranging from 100 to 1,000 RPM. It is the perfect unit for rapidly dispersing powders into liquids and emulsifying standard chemical solutions.

• LR500B (The High-Torque Mixer): Designed specifically for heavy resistance. Featuring a specialized 70W brushless motor, this unit operates at a lower, geared-down speed range of 34 to 340 RPM, trading raw speed for massive rotational torque. It is the ultimate tool for thick polymer synthesis and high-viscosity resins.

Safe, Ergonomic Operation Because mixing heavy fluids can cause significant vibrations, the LR series is housed in a durable, vibration-resistant casing. The unit features an easy-to-use digital or analog speed interface, allowing your technicians to smoothly ramp up the RPMs without splashing dangerous chemicals out of the mixing vessel. The secure chuck head firmly grips a wide variety of stirring shafts and impellers, allowing you to customize the blade type exactly to your fluid dynamics.
