Caps are made of high quality polypropylene to exact manufacturing tolerances and lined in a controlled manufacturing environment. Our septa use only the highest quality materials to ensure proper function and can be pre-slit to ease needle penetration. Designed for single injection and/or short sample cycles, particularly for LCapplications . Absence of elastomer layer reduces potential for contamination.
