Description
Penny head ground glass stoppers are designed to provide a secure and reusable seal for laboratory glassware. Their flat, wide top makes insertion and removal easy, even when wearing gloves, while the precision-ground taper fits snugly in standard glass joints.
Constructed from heavy-quality LabChoice BORO 3.3 borosilicate glass, these stoppers resist chemical corrosion, thermal stress, and chipping. Ideal for sealing flasks, reagent bottles, and apparatus requiring airtight closures, they help prevent evaporation and contamination.
Trusted by labs across Australia, these stoppers are supplied by LabChoice Australia to support safe, reliable containment in chemical storage and lab workflows.
