Check the Maximum Load Tolerance and Speedįor each unit, the manufacturer will specify the maximum load tolerance and the maximum speed. Any imperfection in a vessel should be considered to render it unusable in a centrifuge. Additionally, check caps, O-rings, and adapters to ensure they’re not degraded. Even a tiny fracture could result in the tube breaking easily once the centrifuge is up and running. You should also check the condition of tubes before use. Tubes should be part of a matched set that fits your centrifuge. Before using tubes, check that they are compatible with your application and settings. Inspect Tubes Before UseĬentrifuge tubes should be rated for temperature, speed, and chemical resistance. Metal fatigue was the suspected cause in a 1999 incident at MIT, in which a rotor split down the middle part way through an application. Rotors undergo metal fatigue after repeated use, but may show no visible signs of wear to the everyday user. Rotors should also be inspected regularly by a trained technician. However, the centrifuge itself could end up being destroyed. Many centrifuges are manufactured such that users and other bystanders should not be injured in case of a mechanical failure. If ignored, this can even result in small holes forming, especially where there are already existing scratches and cracks.Īside from shortening the life of your machine, corrosion can render a centrifuge unsafe to operate, and could even lead to rotor failure. Long-term exposure to moisture, salts, and aggressive chemicals can cause corrosion of the rotor and buckets. That movement could potentially throw the centrifuge out of balance. A surface which is not sturdy and stable could move in response to this force. The reason that the whole centrifuge doesn't start spinning in that opposite direction is that it's firmly planted on a non-moving surface. When the rotor starts moving, it creates a rotational force in the opposite direction. It’s also important to have a stable surface to work on. If that's not the case, it would be out of balance, even before you’ve loaded the tubes. Centrifuges are designed with the assumption that the axis of the rotor will be in line with the direction of gravity. An uneven surface could cause the rotor to be imbalanced. It’s important to use most, if not all, pieces of lab equipment on a level surface, but it’s especially important with a lab centrifuge. In this post, we explain these factors in more detail to help you ensure the safe operation of your lab centrifuge. Shut down in event of noise or vibrations. ![]() Check the maximum load tolerance and speed.In order to ensure you and your colleagues remain safe, there are several precautions to take, including: In addition, injury can occur if lab personnel come in contact with moving parts while the centrifuge is in use, and aerosols produced during spinning can pose potential health risks.Īccording to the Occupational Safety and Health Administration (OSHA), most centrifuge accidents occur as a result of user error. ![]() The safety shielding was unable to contain the damaged rotor and metal fragments damaged nearby equipment, walls, and the ceiling. In one case, the shock wave caused by a failed rotor blew out a laboratory’s windows. The resulting flying metal fragments can cause considerable damage and pose a risk to any nearby personnel. The biggest concerns is the potential for injury and damage if a rotor fails. If used incorrectly, a lab centrifuge can be a dangerous piece of equipment. ![]()
