PCR tubes are essential laboratory consumables designed for polymerase chain reaction (PCR) processes. These small, thin-walled tubes ensure efficient heat transfer and precise temperature control during thermal cycling. Key features include: compatibility with most thermal cyclers, high-temperature resistance (up to 120°C), and DNase/RNase-free certification. Common product variations include: 0.2ml single tubes, 8-tube strips (with or without attached caps), and 96-well plates. Specialized options feature flat caps for easy labeling, dome caps for increased volume capacity, or optically clear materials for real-time PCR applications. Many tubes incorporate graduation marks for volume measurement and colored caps for sample identification. Premium versions offer ultra-thin walls for rapid thermal transfer or reinforced designs for mechanical stability during robotic handling.
