Chemglass Hollow Hex Head Glass Stopper 24/40 Lot of 4 Stoppers

The Chemglass CG-3006-01 is a professional-grade Hollow Hex Head Glass Stopper designed for use with standard taper laboratory glassware. These stoppers provide a secure, leak-proof seal for flasks, condensers, and other components while offering ergonomic advantages over traditional penny-head stoppers. The hex head design prevents the stopper from rolling off the lab bench, reducing the risk of breakage and contamination. It also provides a better grip when wearing gloves. Being hollow makes the stopper significantly lighter than solid glass versions, reducing the weight load on delicate glass joints and making them easier to handle. The flat top surface allows the stopper to be stood upside down on its head, further preventing contamination of the ground joint surface.
