Screw Top 8mm Black Plastic Vial Cap, 100/Pk - CV1845
Available in open-center and closed-top configurations, Tisch chromatography caps accommodate diverse sealing requirements across HPLC and GC platforms. Chemical resistance of the polypropylene body ensures the cap contributes no leachable contaminants to the sealed sample environment during extended storage intervals. As designed, reliable component compatibility across the chromatography closure system supports reproducible analytical results from sample preparation through final data acquisition.
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. Standardize your sample containment system on components engineered for the dimensional precision and chemical inertness your chromatographic methods demand.
