Microcentrifuges
Microcentrifuges are designed to process small volumes of liquid samples, usually between 0.2 and 5 milliliters. They are commonly used in molecular biology, biochemistry, and cell biology laboratories for separating substances in liquids based on their density, such as cells, proteins, nucleic acids, and other cellular components. Microcentrifuges are typically compact in size, requiring less usage of valuable workspace. Some models include a standard rotor, while others offer a variety of rotor options for expanded versatility.
Microcentrifuges are often used to pellet cells or organelles, meaning they help collect cells, viruses, or organelles from a liquid sample by spinning it at high speeds. They are also essential in DNA or RNA extraction, where they help separate cellular debris from the target genetic material. Additionally, they are used in protein purification to isolate proteins by removing contaminants. Another key application is the concentration of solutions, such as proteins or DNA, by removing excess liquid or solvent.
