The polycarbonate frame is extremely robust for ultimate rigidity and torque-resistance. The polypropylene wells are extremely thin to allow optimal heat transfer to the sample. The twin. Tec PCR plate unscripted, twin. Tec PCR plate unscripted divisible, and twin. Tec real-time PCR plate unscripted feature an OptiTrack matrix, a high contrast labeling of alphanumeric grid for easier identification of wells and orientation of plate. Both are available with either regular (250 µl) or low profile (150 µl) wells. The twin. Tec PCR plate unscripted divisible can be divided into 4 segments of 24 wells each. The new twin. Tec microbiology PCR plates are ideal for applications that require the ultimate purity or certified absence of bacterial DNA. These plates come sterile, in individually blistered packs. Not only are these certified PCR clean, but free of bacterial DNA as well.
