Hexagonal hollow plug, pointed end (Form C), borosilicate glass 3.3

Hexagonal hollow plug made of high-quality borosilicate glass 3.3 in form C with a pointed end. The hexagonal shape allows for a secure grip and easy tightening with standard tools. Thanks to the standard ground joint (NS), the stoppers are compatible with all common laboratory glassware and equipment.

The pointed, closed design provides a tight seal for reaction vessels, distillation flasks, and other glassware. The borosilicate glass 3.3 used guarantees high chemical resistance, thermal shock resistance, and mechanical stability – ideal for demanding laboratory applications.

The hollow plugs are available in various standard ground joint sizes from NS 5/13 to NS 45/40, thus covering a wide range of applications in chemistry, pharmaceuticals and analytics.
