When a lab bench needs reliable mixing, the decision usually comes down to motion type: a moving surface that sways multiple containers at once or a rotating shaft that works inside one vessel. Both approaches get liquids moving, but they serve different workflows. Here are two mixers that represent those two directions.
Quick verdict
If your work involves cell cultures, staining, or gentle sample mixing, the Labnique Orbital Shaker is the natural pick. If you need to stir thick liquids, the RATTM MOTOR overhead stirrer is built for that kind of workload. The decision comes down to whether you want to move many small containers together or stir a single vessel directly.
Comparison table
| Feature | Labnique Orbital Shaker | RATTM MOTOR Overhead Stirrer |
| Price | $120.00 | $135.00 |
| Motion | Orbital shaking | Overhead stirring |
| Speed range | 0 to over 210 r/min | 100-2000 RPM |

Where each product wins
Think about the containers you load and how long you typically run a procedure. A surface that moves many items at once fits multi-sample workflows, while a shaft that spins inside one vessel fits single-batch work.
- Labnique wins for routine benchtop work where even sample movement is the main goal.
- RATTM wins for more demanding liquid-handling tasks that need a single stirred vessel.
Product notes
Labnique Orbital Shaker 110V Lab Mixer Variable Speed w/ Timer Tested
The Labnique Orbital Shaker 110V Lab Mixer Variable Speed w/ Timer Tested delivers the classic orbital motion many benchtop procedures call for. Its flat rectangular platform has raised edges to hold flasks, bottles, or tubes during shaking. The raised edges are useful when working with multiple vessels of different sizes, because they reduce the chance of items sliding off during runs. The speed dial spans from 0 to over 210 r/min, and the mechanical timer lets you run it for up to 15 minutes or leave it set to continuous operation. Four adjustable leveling feet keep the platform stable on a bench. With its listed use in biological, dental, and cosmetology labs, this $120 shaker fits routine mixing and sample agitation. The most obvious trade-off is that it's a used machine rather than brand-new, and the gentle orbital shake won't handle thick liquids or large-volume stirring the way a high-torque overhead stirrer will.
RATTM MOTOR Electric Adjustable Overhead Stirrer
The RATTM MOTOR Electric Adjustable Overhead Stirrer is the more capable workhorse of the two, with a speed range of 100-2000 RPM, a motor stand height adjustable from 11.8 to 23.6 inches, and a maximum mixing capacity of 40L. The adjustable stand height makes it easy to position the stirrer over deep or shallow containers. Its torque and viscosity ratings also point toward heavier fluids, with a max handling viscosity of 10000 mPa·s and output torque of 40N·cm. At $135, it costs $15 more than the Labnique, but that price buys a new unit and a much broader range of mixing jobs. The limitation is the opposite of the shaker's: it works in one stirring position rather than shaking an entire platform, so it won't replace an orbital shaker for gentle, multi-container culture work.
Final choice by use case
Choose the Labnique when you want a straightforward benchtop workflow. Choose the RATTM when you want a dedicated mixing setup for more demanding mixes. If you often switch between small batches and need predictable agitation, the shaker keeps things simple. If your attention is on one larger or harder-to-mix batch at a time, the overhead stirrer gives you a more direct approach.
