When you're looking at centrifuges, mixers, and shakers for your lab, an overhead stirrer is often the quiet workhorse for routine mixing. The challenge is finding one that handles both viscous liquids and larger volumes without pushing your budget too far. The RATTM MOTOR 160W Electric Adjustable Overhead Stirrer sits in that middle ground and deserves a close look for small labs and teaching spaces.
Quick Verdict
The RATTM MOTOR 160W stirrer is a capable general-purpose overhead stirrer for routine lab work, and its $135 price makes it a reasonable fit. With a 100W motor, it's better for medium-viscosity mixing than for thick slurries.
Who It Suits
If you're preparing buffers, culture media, or similar low-to-medium viscosity solutions, and you need to adjust the stirrer height to fit different containers, the RATTM MOTOR stirrer should match your routine. The adjustable stand works for a range of vessel sizes, and the speed range gives you flexibility for gentle stirring or faster blending.
What Stands Out
The standout details are the maximum handling viscosity of 10,000 mPa·s and the maximum mixing capacity of 40L. The motor output is 100W, and the output torque is 40N·cm, which explains the viscosity ceiling. You get a speed range of 100-2000 RPM, and the stand adjusts from 11.8 to 23.6 inches. At 11.9 pounds, the stirrer is light enough to move between bench positions.
Meaningful Trade-Offs
The main trade-off is torque. This stirrer isn't designed for high-viscosity pastes or thick gels. It will do fine for routine stirring, but don't expect it to maintain high torque at very low speeds. Also, you'll need to make sure your vessels fit within the stand's height range.
Bottom Line
For a lab that needs an affordable, adjustable overhead stirrer for medium-viscosity work, the RATTM MOTOR 160W is a practical choice at $135. It offers a useful speed range and a height-adjustable stand, but keep its torque limits in mind for your specific mixing jobs.
RATTM MOTOR 160W Electric Adjustable Overhead Stirrer
The RATTM MOTOR 160W Electric Adjustable Overhead Stirrer offers a 40L maximum mixing capacity and a speed range of 100-2000 RPM. It handles liquids up to 10,000 mPa·s, and the motor stand adjusts between 11.8 and 23.6 inches. One reason to choose it: the 40L capacity gives you headroom for medium-scale mixing without moving to a larger, more expensive unit. A limitation to keep in mind: the torque output is modest, so it's best suited for low-to-medium viscosity fluids rather than thick, heavy mixes.
