PYREX® Hollow Combination 14/20 Standard Taper Joint and Reagent Bottle Stoppers | Corning 7575-14
$75.06Add to cartPYREX® Hollow Combination 14/20 Standard Taper Joint and Reagent Bottle Stoppers | Corning 7575-14
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.

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.
