I purchased a bag of Sigma-Aldrich rubber septums for 19/22 joint glassware. I am hanging on to a few for my own use, but I have more than I need.
I am wondering if any of you SM members would be interested in buying some of them.
This particular model number has been discontinued, and this is new old stock.
10 rubber septums for $10 (shipping not included, but it will be cheap).
Check out the pictures, and PM me if you are interested.

I do ship internationally, if you were wondering.
Someone just asked me this question.

Is there any interest here for these? Otherwise, I will take them to eBay.
I am not quite sure how many people use 19/22 joints, which *should* also work for test tubes with a 20 mm rim.
Either way, let me know.
