> HF has actually been used right out of the cylinder for a long time in Merrifield peptide synthesizers. It's the traditional way to cleave the peptide off the resin at the final step, so there are actually a lot of people who've used the stuff. But it's in a dedicated apparatus that is (that had better be) well sealed, and people treat it with due respect. At a former employer of mine, there was an accident with one of these machines right before I joined the company. The shout "HF LEAK!" went out into the halls, and I'm told that the whole area set a never-to-be-equaled evacuation record.
