Screw Cap 9mm Black Plastic Vial Cap, 100/Pk - CV1957
Manufactured from chemically resistant polypropylene, Tisch screw-thread caps provide a dependable seal without introducing extractable contaminants into analytical samples. Chemical resistance of the polypropylene body ensures the cap contributes no leachable contaminants to the sealed sample environment during extended storage intervals. Standardized dimensional compliance across the full product line enables confident cross-platform deployment without instrument-specific qualification testing.
When your analytical methods require consistent sample containment from preparation through injection, every component in the closure system matters. Chemical resistance and color-coded identification options let you organize your sample trays efficiently without introducing extractable contaminants into the sealed environment. Ensure your analytical results reflect true sample composition rather than containment variability by selecting vials, caps, and septa built to consistent specifications.
