Description
Hollow stoppers are designed to provide a secure seal for glassware joints while minimizing weight and pressure on delicate apparatus. Their ground-glass taper ensures a tight, leakproof fit across standard joint systems.
The lightweight design reduces the risk of joint cracking, especially in vertical or suspended setups, making these stoppers ideal for distillation columns, condensers, and reaction flasks. They are reusable and autoclavable, offering long-term value for laboratory operations.
Manufactured from heavy-duty LabChoice BORO 3.3 borosilicate glass, they deliver excellent thermal and chemical resistance. Supplied by LabChoice Australia, these stoppers are a dependable solution for sealing precision labware in both research and industrial environments
