Choosing between a rocking platform shaker and a clinical centrifuge comes down to the motion your work actually needs. Both sit in the same benchtop category for centrifuges, mixers, and shakers, and both are listed as tested and working. But they are not interchangeable: the VWR moves a tray side to side, while the Medline spins tubes at a fixed rate. The comparison below lays out the key differences, then each product note gives you the details that matter before you buy. This head-to-head looks at prices, conditions, and the jobs each tool handles so you can choose the one that fits your daily workflow.
Quick verdict
If your protocol calls for gentle tilting agitation, the VWR Rocking Platform Shaker 10860-662 is the direct answer. If you need a simple clinical centrifuge for routine separation and you want to keep costs down, the Medline 642M is the lower-cost option. They are not competing for the same job; the choice is about which motion your protocol needs.
At a glance
| Feature | VWR Rocking Platform Shaker 10860-662 | Medline 642M Centrifuge |
|---|---|---|

| Condition | Used | New - Open box |

Where each wins
The VWR wins when the task is low-impact tilting agitation, such as gel blot rocking. The Medline wins when the goal is straightforward centrifugal separation and a lower purchase price. In short, one moves samples side to side; the other spins them down. The right pick depends entirely on whether your lab needs to mix gently or separate by centrifugal force.
Product notes
VWR Rocking Platform Shaker 10860-662
The VWR gives you a single rocking platform with a drive that powers on and rocks across multiple speed settings. Its maximum of 120 tilts per minute is a low-impact range that suits gel blot rocking and similar gentle mixing. The limiting detail is the 230 V nameplate: this unit is labeled for 230 V, so your power input has to match before you put it to work. The single-platform setup keeps the footprint simple, and the verified power-on behavior means you can plan around an instrument that is ready to run once the voltage question is settled. If your bench needs a rocking motion rather than a centrifuge spin, this shaker is the one to pick.
Medline 642M Clinical Lab Centrifuge
The Medline 642M is a single-speed clinical centrifuge built for consistent separation of fluids and particles. Its single-speed operation is both the main benefit and the main limit: you get a repeatable, straightforward spin, but you cannot dial in different RPMs for protocols that need variable speed. It is a new-open-box unit from the United States, which gives you a clean start if you are looking for a dedicated centrifuge. For clinical lab routines that rely on one dependable speed, this model covers that need without extra controls. If you need a centrifuge for everyday sample preparation, this one keeps the operating steps minimal. Just confirm your tube types and separation tasks fit a fixed-speed centrifuge before you buy.
Final choice by use case
Pick the VWR for gel blot work and gentle platform rocking, and make sure the 230 V label is compatible with your power. Pick the Medline when the job is clinical separation and a $60.01 lower price matters more. Different motions, different daily workflows; choose according to what your bench does.
