Jennifer Hritz | General | Optical Contacting | Samples after 2 weeks under pressure | Since I was focusing on the hot plate code
and therefore did not need my weights, I
decided to leave them on top of my samples |

I wanted to do my first real test with actual
samples. Since everything went smoothly, |

by getting rid of the feature that increases
the heating rate so I can isolate the base |

would heat up if the heat was just on constantly

faster than the top plate, I decided to try
increasing the cycle period from 1000ms (1s) |
