Has your lab’s centrifuge been “balanced” today?

Overview:
Laboratory centrifuge There are many types available, but the desktop models remain popular—they’re easy to place and relatively compact. However, they’re slightly larger than mini centrifuges.
Common laboratory centrifuges typically include benchtop high-speed centrifuges, low-speed centrifuges, and benchtop high-speed refrigerated centrifuges with freezing capabilities.
In fact, the selection of high- versus low-speed laboratory centrifuges depends on the nature of the experimental sample. It’s not necessarily true that higher speeds are always better and lower speeds always worse. Some experimental substances actually require low speeds for effective separation—this is quite common. In short, when choosing a laboratory centrifuge, you should base your decision on the specific needs of your experimental samples. Communicate more with suppliers, and if necessary, consider customizing the equipment to meet your requirements.
For other functions—such as freezing, handling large or small sample volumes—just think of it the same way you’d approach selecting between high- and low-speed modes. By clearly understanding the potential scenarios your experiment might involve, you’ll be able to choose the right laboratory centrifuge with ease!
Actually, choosing a laboratory centrifuge shouldn't be something to fear—what really matters is “balancing” it properly. There’s a saying online: “A lab centrifuge that hasn’t been balanced is just a blood-spatter machine.” And that’s actually not an exaggeration at all. First of all, when a centrifuge isn’t balanced, this is what happens during operation:
1. The noise is loud—really loud! How loud? So loud that you’d start to wonder if it’s about to explode!
2. The vibration is intense—how intense? Intense enough to fling the centrifuge lid off entirely, turning it into a “blood droplet”!
Therefore, the “balancing” of a laboratory centrifuge is crucial. To explain how to do it in detail, we’d need to conduct specific experiments and analyze each case individually. However, as a general guideline, you can refer to the following steps:
1. Fixed-angle rotation
For centrifugal force with a fixed angle of rotation, simply silently recite, “The Law of Central Symmetry is Great!”
2. Horizontal rotor
What gives the experimentalist the biggest headache is balancing the horizontal rotor.
When balancing, you must consider not only whether the samples within a single basket are symmetrical, but also whether the samples in opposing baskets are balanced.
The following balancing tips are based on years of market experience from Shanghai Luxiangyi Centrifuge Instrument Co., Ltd. and we hope they will be helpful to everyone:
⊙ When placing samples inside a single basket, ensure that the basket’s center of gravity is located at the center point of the basket.
⊙ When placing samples in opposing baskets, use the sample placement in one basket as a reference and strictly adhere to the principle of symmetry about the rotor’s center point.
