Need an efficient way to spin down tubes for a small medical, lab, or PRP setup? The choice usually comes down to tube capacity, portability, and how much electronic control you want. One machine is a compact portable unit that spins six 20ml tubes; the other is a larger desktop model that takes eight 15ml tubes. Among the centrifuges mixers shakers options in this range, the Portable Medical Lab Centrifuge Electric PRP Centrifuge Machine 4000rpm 6x20ml is listed at USD 69.44, while the 8x15ml Medical Beauty PRP Lab Blood Centrifuge Machine 110V Low Speed Centrifuge is listed at USD 178.32. That puts about USD 108.88 between them, so the decision is as much about workflow and workspace as it is about price.
Quick verdict
Go with the 6x20ml portable electric centrifuge when mobility and a lower price point are the priorities. Go with the 8x15ml PRP lab blood centrifuge when you want a desktop machine with digital control and more tube slots.

Where each product wins
The 6x20ml portable model wins on portability and price. It is light enough to move around and pairs its 4000 rpm speed with 2086 xg of relative centrifugal force, which is slightly higher than the desktop model's 1880 xg. If bench space is limited and cost is a concern, this machine is the easier choice to justify.
The 8x15ml PRP model wins on tube count and lab-style control. It gives you eight tube positions and microcomputer control, which makes routine blood, vaccine, and PRP runs easier to set up.
Portable Medical Lab Centrifuge Electric PRP Centrifuge Machine 4000rpm 6x20ml
If you want a centrifuge that can sit on a bench and still move easily between rooms, this compact white unit is the one to start with. The step-less speed and time knobs make run setup simple, and the ABS plastic turntable plus easy-to-clean body reduce routine hassle. At roughly 1.7 kg / 3.74 lbs, it feels lighter than a typical benchtop centrifuge, and the trouble-free installation suits a home lab or small clinic. The trade-off is the six-tube rotor: if your normal batch is eight 15ml samples, this machine will make you run extra cycles.
8x15ml Medical Beauty PRP Lab Blood Centrifuge Machine 110V Low Speed Centrifuge
For PRP, blood, or vaccine separation with a fixed-angle desktop rotor, this model is built around a brushless DC motor and microcomputer control. The digital display lets you set speed and centrifugal force, and the electronic door lock plus overspeed protection add useful safeguards during a lab run. Its automatic balance feature means you do not need to spend time manually balancing tubes, which is handy when you are processing eight 15ml tubes. The main limitation is the 110V / 60HZ input requirement, so this centrifuge belongs in a workspace with that power setup. It is also a 5 kg desktop unit, not a portable one.
Final choice by use case
Choose the portable 6x20ml centrifuge for a small lab, clinic, or occasional-use setup where budget and floor space are tight and you work with a few larger tubes. Choose the 8x15ml PRP lab blood centrifuge for a 110V lab or medical beauty setting that runs regular 8-tube batches of 15ml blood or PRP samples and wants digital control, brushless motor drive, and automatic balancing.
