The pharmaceutical industry has a history of developing innovative medicines and novel drug-delivery systems, but not all of its manufacturing processes use cutting-edge technologies. Demands to increase productivity in fill–finish lines are fueling the arguments of proponents of robotic automation to expedite manufacturing.
I work in a quality control laboratory and use a pH meter with a single-junction reference probe to test samples taken from various pharmaceutical (drug) production lines. The probe I use has a six-month warranty. It slowly stops working after just a couple weeks. I am replacing it once a month. We make sure to store it correctly according to the manufacturer's specifications and even use probe cleaner at the end of each shift to ensure that it stays clean. What can I do to increase the lifespan to at least cover the warranty period?
