These versatile caps combine secure screw-cap closure with septum sampling capability, allowing material addition or removal without opening the tube. Each cap includes a PTFE-backed silicone septum optimized for clean, reliable access using standard 22-gauge needles.
Available in two configurations: septum caps for sampling applications, or solid polypropylene caps with PTFE liner for permanent sealing. Both styles are compatible with 5mm and 10mm screw-cap NMR sample tubes.
