Labasics Glass 50ml 3 Neck Round Bottom Flask RBF, with 24/40 Center and Side Standard Taper Outer Joint 500ml LB-RBF-3Neck-24/40-Glass-500ml 1

This is a great value on a piece of glassware like this. In the interim until I got the proper size glass stoppers, I tried a rubber one, but unfortunately I started with a size #4 which became seriously wedged in the neck. After several failed methods of trying to remove it, I was able to destroy the stopper and I'm glad the glass sustained no damage. A #5 rubber stopper has worked perfectly since. Would highly recommend,

Love the quality and utility!
