PCR Tubes
PCR tubes hold the PCR reagents (sample, primers, dNTP, polymerase etc.) in a PCR thermocycler machine. They may be available as individually isolated tubes or as strips of tubes. These tubes are slightly smaller than the usual microcentrifuge tubes. Their usual capacity is 0.2. Both colored and colorless versions are available. PCR tubes have a domed cap or a flat cap which fits better on different types of instrument. Conventional PCR as well as qPCR both require these tubes. They may also be used for other assays involving smaller volumes. They are made of polypropylene and are durable and have a uniform thickness to evenly distribute heat and tight sealing to prevent loss of volume due to evaporation. These tubes are autoclavable and reusable.
