Pack of 10 Wooden cork

A wooden cork is a type of closure used in science labs for sealing glassware, such as bottles, flasks, or test tubes. It is typically made from natural cork material sourced from the bark of cork oak trees. Wooden corks provide an effective seal to prevent evaporation or contamination of the contents. They are commonly used in chemical storage, reactions, or aging processes where a non-reactive and reliable closure is required.
