Drierite® DRY-TOPS (24/40 Desiccant Stoppers)

DRIERITE® DRY-TOPS are custom stoppers for 24/40 neck flasks with a refillable inner chamber housing DRIERITE® desiccant. They enable both temporary and long-term storage in an anhydrous environment without requiring a desiccator. The stoppers feature a vapor-permeable and chemically resistant membrane to ensure the desiccant never contaminates samples. A translucent stopper body allows monitoring of indicating DRIERITE® color changes (blue to pink) for constant visual assurance. Advantages include keeping reagents and samples dry in flasks, vials, and bottles; fitting standard 24/40 joints; and being refillable and cleanable.
