The analysis supported the use of Saran wrap as a preferred product but vindicated the use of Handiwrap if it were needed. The results are included with this report. The incandescent track lamps over all core laboratory work areas were replaced with halogen fixtures. Mechanical fixes kept both units functional, but problems with the interface boxes and control software mandated that they be used in manual mode only, a slow and tedious process. The problem was studied on the transit to Leith, and the results will be submitted to the laboratory working group.
Problems persist with weakly magnetized material being overprinted by drilling operations.
Few problems were associated with the equipment in this laboratory. A replacement pycnometer proved trouble-free, although it was a little more complicated to operate. The MST was used heavily with no problems attributed to the drive mechanism, computers, or sensors. Maintenance of the other laboratory equipment was routine. The poor functioning of several instruments was attributed to work and repair inexperience.
