These hollow PYREX® 14/20 Standard Taper joint and bottle stoppers are closed at the bottom. They are interchangeable with standard taper joints and bottle stoppers of the same size. These hollow stoppers are light in weight, yet very strong to reduce chipping and breakage, thus minimizing replacement costs. A barrel-shaped head means it is easy to clean and even easier to rotate in or out. Grooves in the sides help prevent slippage. The flat top allows the stopper to stand on its head, which frees the user's hand and minimizes potential contamination. These are replacement parts for organic chemistry kit No. 6949K.
