mikrocentrifug

A mikrocentrifug, also known as a microcentrifuge, is a laboratory device used to separate components of a liquid sample based on their density through the process of centrifugation. It is commonly utilized in molecular biology, biochemistry, and clinical laboratories for the rapid separation of small-volume samples, typically ranging from 0.1 to 2 milliliters.

The mikrocentrifug is characterized by its compact size, making it suitable for bench-top use where space is limited. It typically features a motor-driven rotor that holds microtubes or other small containers, and a control panel to adjust the speed (measured in revolutions per minute, RPM) and duration of the centrifugation process. Many models include safety features such as lid locks and imbalance detection to ensure safe operation.

Operation of a mikrocentrifug involves placing the sample tubes into the rotor, closing the lid, and setting the desired parameters. Once activated, the rotor spins at high speeds, creating a centrifugal force that causes denser particles or cellular debris to move outward and settle at the bottom of the tube, while lighter components remain in the supernatant.

Mikrocentrifuges are essential in protocols such as DNA and RNA purification, protein isolation, and the removal of precipitates from solutions. Advances in technology have led to the development of more quiet, energy-efficient, and user-friendly models.

Overall, the mikrocentrifug is a vital tool in modern laboratory workflows, enabling quick and efficient separation of small-volume samples for analysis and experimentation.
