Näytemikroputket

Näytemikroputket, often referred to as microcentrifuge tubes or Eppendorf tubes, are small plastic tubes used in laboratories for holding and processing samples. These tubes are typically made of polypropylene and come in various volumes, commonly ranging from 0.1 mL to 2.0 mL. Their design usually includes a hinged lid to prevent evaporation and contamination, and a conical or domed bottom for easy sample retrieval.

The primary use of näytemikroputket is in molecular biology, biochemistry, and clinical diagnostics. They are indispensable for techniques such as DNA and RNA extraction, PCR (polymerase chain reaction), centrifugation of small volumes, sample storage, and reaction setup. The small size of these tubes minimizes reagent and sample waste, making them cost-effective for numerous experimental procedures. They are designed to withstand centrifugation at high speeds, although specific maximum speeds vary depending on the tube's material and design. Many näytemikroputket are sterile, disposable, and autoclavable, ensuring experimental integrity and preventing cross-contamination. They are a fundamental tool in virtually all biological and chemical research laboratories.
