The AST PCR cabinet has been specifically designed for gene-amplification work using the PCR technique (Polymerase Chain Reaction). A digital timer, inverter and two 18W UV tubes have been included to ensure the material placed inside, as well as the entire work surface, is completely sterile, thus preventing any possible cross-contamination between the DNA and RNA samples that may give rise to false-positives. The 4mm-thick tempered glass works as a filter to protect the personnel and the environment from UV radiation.
