#LifeInTheLab Purging samples from a downed freezer today, and found a couple of boxes, labelled "No. 47 SCARY: BE CAREFUL" and "No. 48 ALSO SCARY" respectively. No study IDs, just the warning. Opening the boxes, we discovered they contained glass whole blood collection tubes, and as you might guess, a lot of the glass had shattered, after being stored at -80 deg C for twenty years--yes, some of these tubes were 20 years old. 🥶 #ScienceMastodon
