Quick Verdict
Between these two lab tools, the decision is about what kind of work you do. The Portable Medical Lab Centrifuge is the choice when your task is spinning small tubes and separating solutions. It costs $69.44. The Electric Overhead Stirrer is the choice when you need to stir and mix larger volumes in a vessel. It costs $89.02, making the price difference $19.58. The gap matters less than the intended use: one machine separates, the other mixes.

Where Each Product Wins
- Spinning tubes: The Portable Medical Lab Centrifuge is the one to reach for when you need to spin down samples in tubes.
- Mixing vessels: The Electric Overhead Stirrer is the one to reach for when you need consistent agitation in larger containers.
Product Notes
Portable Medical Lab Centrifuge Electric PRP Centrifuge Machine 4000rpm 6x20ml
This centrifuge tackles the jobs that require spinning down small tubes. It gets up to 4000rpm, which is useful for compact benchtop work. The step-less speed and time knobs let you adjust a run smoothly without hunting through menus, and the alarm design gives a clear signal when the cycle finishes. Its high-strength ABS turntable is easy on centrifuge tubes, while the small, lightweight build makes it convenient to move from one workspace to another. The main limitation is capacity: with six 20ml tubes, it is meant for smaller sample volumes, not bulk mixing. If your lab's routine is sample prep in standard small tubes and you want a compact tool, this model fits that role without adding complexity.
Electric Overhead Stirrer Max.40L Digital Lab Mixer Time & Speed Adjustable 120W
If your work involves larger volumes, this overhead stirrer is built for that. The 120W DC permanent magnet motor drives mixing up to 40L, and the speed range of 100-2000rpm gives you room to adjust from gentle stirring to more intense agitation. The digital tube screen makes time and speed settings easy to read, while the 0.8-10mm drill clamping range gives flexibility in the shafts you can attach. Maximum torque of 40N·cm and maximum viscosity of 30000mPa.s indicate it can handle thick, demanding mixtures. The trade-off is that it is a mixer, not a centrifuge: if your protocol calls for spinning and separating solutions in tubes, this stirrer will not do that job. For labs that need consistent high-volume mixing with adjustable speed and time, it offers a solid combination of power and control.
Final Choice by Use Case
Pick the Portable Medical Lab Centrifuge for small-tube prep and PRP-style preparation. Pick the Electric Overhead Stirrer for large-batch liquid mixing. If your lab has both needs, keeping both on hand makes sense.
