The hollow PYREX stopper is 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抯 hａnd and minimizes potential contamination. This PYREX stopper is interchangeable with other common flask stoppers and fits all standard labware of comparable size.
