First – Friday evening when doing the night rounds in the BION there was a note on the board stating that one of the double containment containers that hold the acids had liquid in it. These type of things need to be brought to the staffs attention (lab staff or front office) right away. The note wasn’t seen until 6 pm so the length of time the liquid was there is unknown and by that time Jake had no support in the clean up.
Second – We have still been having contamination issues with SU-8 spinner in the hot embossing area. When checked last Friday night, the spindle that drives the chuck was contaminated and would not allow it to start up. Also the vacuum valve was stuck in the open position. This has been happening at least once a week. If you are unsure how to operate the equipment properly please see staff as this effects the work of others around you.
