5mm NMR Tube Septa, 100 Pack
These precision molded natural rubber septa for 5mm and 10mm NMR sample tubes seal against both the inner and outer surfaces of standard, thin wall NMR tubes, providing the ultimate protection for sensitive or reactive samples, isolating them from contact with air, moisture and other ambient contaminants.
This dual seal septum likewise protects personnel against exposure to samples that may pose health or safety hazards, while still allowing easy access through the septum, using a syringe, to add, transfer or retrieve samples from the NMR tube.
