You are bidding on a lot of 18 pieces of lab glass.
The majority of the glass is Pyrex.
A few pieces are a lab glass marked with a K.
Unfortunately I do not know what many of these pieces are so I uploaded pictures of each.
Their are 3 of the "sideways" T looking glass connector.
The sizings on these are 10/30 for the smaller end and 24/40 for the thicker end.
Their are 2 elbow like pieces of glass with the nipple.
The end is sized 24/40 on that piece.
The one "h" shaped glass is sized 24/40 on the thick end and 10/30 on the smaller end.
The valved piece is sized 12/18 on one end 24/40 on the other.
There is a few other pieces and a stopper as well.
Any questions feel free to ask. I will answer them the best I can.
Good luck bidding!!!!
