Using Bodum glass in the lab

hullumies - 30-10-2013 at 22:50

Hi,

Does anyone here use Bodum glass in the lab? From what I understand, all of it is borosilicate. The espresso glasses, for example, come with a nice, removable plastic handle and they can be picked up for about 50 cents each all day long at the second hand stores. The french presses could also make nice beakers.

Thanks.

should be ok, just make sure you label it in such a way to ensure that you dont mix it up with your ktchenware, i also reccomend storing it away from where food is prepared/served

well get some and put it to a test comparing it to lab glass? such as impact etc if it is that cheap

Isn't Bodum more expensive than pyrex?

The new price of Bodum glass is more expensive than pyrex, but as I said there is a whole lot of it available in the local second-hand stores. I guess I will buy one of the espresso glasses for about 50 cents and do a boil then straight into an ice bath. If it works, it could be very good material for blowing custom glassware.

My main question, I suppose, is that will it be just as resistant to chemical attack as real lab glass? Is it a case of "there's borosilicate, and then there's borosilicate"?

Yes. I have a small Bodum dish which I use for recrystallizations sometimes. Its base explicitily says not to use it on a stovetop. There are indeed different grades of borosilicate (for example, volumetric flasks are made from another type of borosilicate than RBFs and the like). It should however resist chemicals easily.
