Closed-End Quartz Capillary Tubes for Radioactive Sample Storage

These closed-end quartz capillary tubes are engineered specifically for the room-temperature storage of radioactive laboratory samples.
Made from high-purity fused quartz, they provide exceptional chemical resistance, low metal ion content, and high optical clarity—properties essential for research environments handling sensitive or trace-level radioactive materials.

Each tube features a precision-formed rounded closed end, ensuring secure containment of small-volume samples without the need for wax, grease, or temporary sealing materials. This design offers improved cleanliness, structural reliability, and workflow consistency for sample preparation and storage.
