As a reminder-


- We should ALWAYS examine the glassware before we use it before we are about to set up. I have seen where a scratch in a beaker caused it to shatter during an experiment /process.

My thanks to everyone for sharing their thoughts on my question yesterday. I want to point out that the faculty member asked for my help in assessing this risk rather than just ignoring the various warnings etched into the glass by the manufacturer.

The question arose because the member had detected defects in the existing carboys, which are likely to be 40 years old, and had ordered replacements, which included 6 vague warnings, including the reference to the technical information that we couldn't find on their web site. The suggestion to talk to a company rep is the next step.

It is helpful to be reminded of the energy levels involved in pressurized gases, but that was not news to either of us. I do appreciate having the stories people shared with me about bad experiences they've had with similar set ups.

Thanks to everyone for their assistance with this question.

- Ralph
