Description
The National Scientific C4013-64A offers a pack of 200 black screw caps specifically designed for 8 mm opening vials or bottles commonly used in chromatography applications. Made from chemically inert polypropylene (PP), these caps are compatible with a wide range of solvents used in chromatography. The black color minimizes light exposure, potentially beneficial for light-sensitive samples. The screw cap design ensures a secure and leak-proof seal, while the pre-slit septa allows you to inject or withdraw liquids through the vial without removing the cap completely. This minimizes contamination risks during sample preparation or analysis in your chromatography experiments.
