Key features and components of a hand-held centrifuge include:
- Hand Crank or Manual Operation: Unlike traditional centrifuges powered by electricity, a hand-held centrifuge is operated manually by a hand crank or a similar mechanism. Users rotate the crank or handle to generate the centrifugal force needed for sample separation.
- Sample Holders: Hand-held centrifuges typically include tube holders or adapters to accommodate small sample tubes. These holders keep the tubes securely in place during the centrifugation process.
- Rotor: The rotor is the part of the centrifuge that holds the sample tubes during spinning. It is usually a fixed-angle rotor, which means the tubes are positioned at a constant angle relative to the axis of rotation.
- Lid or Cover: The hand-held centrifuge is equipped with a lid or cover that ensures the safety of the operator during centrifugation. It prevents the tubes from accidentally opening and spilling their contents.
- Timer: Some hand-held centrifuges may have a built-in timer or a visual indicator to monitor the duration of centrifugation accurately.
- Material: Hand-held centrifuges are often made of durable materials, such as plastic or metal, to withstand repeated use and handling.
Hand-held centrifuges are particularly useful in scenarios where access to electricity is limited, or when a rapid on-the-spot separation of samples is required. They are commonly used in remote fieldwork, point-of-care clinics, and for various diagnostic tests in resource-limited settings.
