− | <p>The working internals of our PCR machine are comprised of hairdryer elements. With the exception of the hairdryers outer housing, the thermal fuse and bimetallic circuit breaker all other working components remain intact. The thermal fuse and bimetallic circuit breaker were shorted using copper wire in order to reach temperatures up to 95 within our machine. The outer plastic housing of the hairdryer was also removed to enable our machine to stand upright and fit PCR tubes. The hairdryers heating mechanism which utilizes a bank of nichrome wires and fan that distributes the heat remained untouched. | + | <p>The working internals of our PCR machine are comprised of hairdryer elements.
