PCR tube design and thickness offers the perfect seal, since the seal between the tube opening and the tube cap is critical in minimizing evaporation or sample leakage. Loose caps allow evaporation; overly tight caps cause spillage upon opening.
PCR tubes are ideal for high-throughput PCR applications such as multiplex PCR and gene expression studies. These tubes are made of polypropylene and have a uniform wall thickness which makes them very durable and able to withstand repeated thermal cycling. The PCR Tubes feature a flat bottom and a domed lid to ensure a secure seal and prevent evaporation. Each tube also has a clear window at the top to allow for easy sample identification. PCR tubes are non-sterile, certified RNase and DNase free.
