I can say that were I work in a lab, virtually half or more of all glassware has one or more chips in it, with no issues. We use it all daily, and
it gets wear to it, scratched bottoms from stirbars over the years, chips on edges, and etching from some reactions. If there are actual star cracks
or real cracks, we typically either toss it, or relegate it to minor use, not under vacuum, but I used a few beakers with minor cracks in them for
years for cleaning small parts in with acetone, and they did not even leak. So when I see how afraid people are of minor chips or broken off drip
tubes, I have to sign, as that is most of what I use daily, and it works fine. |
