We will be temperature mapping the shelves of our lyophilizer to determine uniformity. My question is how are others ensuring that good contact is made between the thermocouple and the shelf. I know there is a very expensive device available that will hold the TC in contact with the shelf. I’m wondering what other technicques others have used. We have used “pucks” and lyo trays to hold the TCs down in the past with limited success. I’ve looked for an appropriate compound to attach the TC to the shelf that is thermally conductive and will not leave an a problematic residue, but haven’t found anything yet.
Thanks in advance for your help!
