kurvrotorer

Kurvrotorer, also known as basket rotors or centrifugal extractors, are a type of rotor used in centrifuges. They are characterized by their open, basket-like design where the sample tubes are held vertically or at a slight angle. This design is particularly advantageous for applications where samples need to be processed without disturbing the pellet or separating liquid layers significantly.

The primary function of a kurvrotator is to generate centrifugal force, causing denser components in a sample to settle at the bottom of the tube. The open design allows for easy loading and unloading of tubes. Unlike fixed-angle rotors, the tubes in a kurvrotator swing out to a horizontal position during centrifugation, which can influence the separation dynamics and the shape of the resulting pellet. This swinging motion is a key feature that distinguishes them from other rotor types.

Kurvrotatorer are commonly found in laboratory centrifuges used in various fields, including molecular biology, biochemistry, and clinical diagnostics. They are suitable for tasks such as cell pelleting, DNA/RNA isolation, and the separation of blood components. The speed and duration of centrifugation are adjusted based on the specific application and the density of the components being separated. The versatility and ease of use make kurvrotatorer a staple in many research and diagnostic laboratories.
