What was done

Basically, we started to make micro-channel chips again. This time with the SU-8 photo resist which is to familiarize ourselves in making the chips when the real materials come in a few weeks time.

Like the previous experiment that we did in the first 3 weeks, the same procedures can be applied to this week’s experiment.

We started by cutting the glass into smaller desired pieces before the edges were blunted. This is to prevent the glass pieces from having sharp edges which may cut our fingers when handling it. The glass pieces were then rinsed several times so as to ensure that the glass pieces are sterilized.

We ended the experiment by heating up the glass pieces to dry and disinfect in at the same time at a temperature of 200 degrees Celsius for 30 minutes. The glass pieces were then left to cool before being stored at a safe place.

Conclusion

We did not manage to complete the experiment as there was not enough time. Though there was a lot of waiting time, we managed to use the time efficiently by reading up on the chemical SU-8 which will be useful for next week’s experiment. We hope that we can have enough time to play around with the chemical which will require different set of instructions as opposed to the common photo resist in the lab.
